American Lock AME-A1166KD BLK 2KEY – Frequently Asked Questions

1) Will the American Lock A1166 padlock fit a lockout hasp or a hole with a 1/4 inch shackle?
The A1166 uses a 1/4 inch diameter shackle with 1-1/2 inch of vertical clearance and 25/32 inch between the shackle legs. That 25/32 inch inside width is the number that decides whether it drops through a lockout hasp jaw or a padlock eye, and the 1/4 inch diameter is the number the hole has to accept. Body is 1-1/2 inch wide solid aluminum, so it sits flat against a hasp without a lot of overhang.
2) Is a keyed different padlock the right choice for a lockout tagout program?
Keyed different is the standard for personal lockout locks: every A1166 opens on its own key only, so no other worker can remove your lock. That is what OSHA-style one-worker-one-lock practice wants. If you instead want one key to open a group of locks (a supervisor set, or a crew sharing access), American Lock builds the same lock as the A1166KA keyed alike, and A1166MK / A1166KAMK for master keyed versions. Uncombinated (A1166UN) and zero-bitted (A1166KZ) ship for a locksmith to pin to an existing system.
3) Can the American Lock A1166 be rekeyed into our existing key system?
Yes. The A1166 uses a 6-pin APTC14 rekeyable cylinder with over 40,000 key changes, so a locksmith can pin it to your combination rather than living with the factory key. If you are keying a batch yourself, order the A1166KZ zero-bitted or A1166UN uncombinated version instead of the keyed different A1166 so you are not paying for a bitting you throw away.
4) What else could I buy instead of an American Lock A1166 aluminum safety padlock?
Within safety padlocks, ZenSupply stocks the ABUS 74/40 insulated safety padlock, which matches the A1166 on the two numbers that matter for hasp fit, 1/4 inch shackle diameter and 1-1/2 inch body width, and also runs a 6-pin cylinder, but wraps the body in insulation rather than anodized aluminum. The ABUS 76/40 is a plastic-covered aluminum core lock at 1/4 inch shackle diameter and 1-37/64 inch wide. If you need a smaller body for tight breaker panels, the ABUS 72/30 is 1-1/4 inch wide with a 3/16 inch shackle, which will pass through holes the A1166 will not.
5) I need padlocks that take our small format interchangeable core, is this one?
No. The A1166 is a rekeyable pin tumbler padlock, so a locksmith repins the cylinder rather than swapping a core. If your facility standardizes on interchangeable cores so security can rotate them without a locksmith, look at the Sargent 60-858-2 removable core padlock, which has a 2 inch stainless steel shackle. That is a different lock class from a colored aluminum lockout padlock, so it is the right call for building security, not for personal LOTO locks.
6) What replaces the American Lock A1166 on a wet or washdown exterior application?
The Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less pop-out cylinder, which is the build used where the lock sits exposed to weather. The American Lock A1166 is anodized aluminum with a corrosion resistant finish and a chrome plated boron shackle, rated by American Lock for tough environments and food processing. The 521 G8R needs a cylinder ordered with it; the A1166 arrives with its 6-pin APTC14 cylinder in place.
7) What is the closest aluminum safety padlock to the American Lock A1166 if I need a smaller body?
The ABUS 72/30 anodized aluminum safety padlock has a 1-1/4 inch body width and a 3/16 inch shackle diameter, so it sits narrower than the A1166's 1-1/2 inch aluminum body and 1/4 inch shackle. Both are anodized aluminum lockout-style bodies. The narrower 72/30 body and thinner shackle fit tighter hasps and smaller breaker clamps; the A1166 keeps the heavier 1/4 inch boron shackle for the same 1-1/2 inch class of opening.
8) Which safety padlock matches the American Lock A1166 body width and shackle diameter most closely?
The ABUS 74/40 insulated safety padlock uses a 1-1/2 inch body width and a 1/4 inch shackle diameter with a 6-pin cylinder, the same body width, shackle diameter and pin count as the American Lock A1166. The difference is construction: the 74/40 is an insulated body, while the A1166 is solid anodized aluminum with a boron alloy shackle. For an electrical lockout point where an insulated body is specified, the 74/40 covers the same dimensions.
9) What should I specify instead of the American Lock A1166 if my facility standardizes on interchangeable core?
The Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle, so the cylinder pulls with a control key and drops into the facility's existing core system. The American Lock A1166 is rekeyable at a 6-pin APTC14 cylinder rather than a removable core, and carries a 1-1/2 inch shackle clearance with a 1/4 inch boron alloy shackle. Facilities already keyed on removable cores usually run the 60-858-2; sites keying padlocks on their own bitting stay with the A1166.
10) Is a Sargent 758 padlock a substitute for the American Lock A1166 on a lockout point?
They are not the same tool. The Sargent 758 is a key retaining standard padlock in a US4 satin brass finish, meaning the key cannot be withdrawn while the lock is open. Key retention is the opposite of what a lockout/tagout program wants, where the worker carries the key away from the applied lock. The American Lock A1166 is an anodized aluminum body built for lockout tagout and food processing, supplied keyed different with over 40,000 key changes. Use the 758 as a general brass-body padlock and the A1166 where a lockout padlock is called for.
11) What is the difference between American Lock A1165, A1166 and A1167?
Those three are the same 1-1/2 inch wide solid aluminum rekeyable padlock with different shackle heights. The A1166 carries a 1-1/2 inch shackle. If you need a taller or shorter shackle to get around a thick hasp or a gate loop, the A1165 and A1167 are the siblings in the same family, same body, same 6-pin rekeyable cylinder. Pick the shackle first, then the color and keying.
12) Can I get American Lock A1166 padlocks in different colors to tell departments apart?
Nine lockbody colors are made: black, blue, brown, clear, green, orange, purple, red and yellow. On a lockout program that is how crews get assigned a color per trade or per shift, and the anodized finish carries the color rather than paint that chips off in a wash-down bay.
13) How many keys come with an American Lock A1166 and can I order it with none?
Standard is 2 keys per lock. You can also order 0, 1, 3 or 4 keys per lock. Zero keys is the usual pick when a facility keys its own locks or does not want spare keys floating around the plant; 3 or 4 makes sense when a lock is shared across shifts.
14) I need color-coded lockout padlocks but with a non-metallic outer body. What should I use instead of the A1166?
The ABUS 76/40 is a plastic-covered aluminum core padlock with a 1/4 inch shackle diameter and a 1 37/64 inch width, matching the A1166's 1/4 inch shackle while wrapping the aluminum core in plastic. The A1166 gets its color from a black anodized or colored anodized aluminum body offered in black, blue, brown, clear, green, orange, purple, red and yellow. Choose the 76/40 where a plastic outer surface is wanted; choose the A1166 where the anodized finish is required, such as food processing lockout.
15) What is the non-key-retaining brass alternative to the American Lock A1166 for exterior gates?
The Sargent 858 is a non-key retaining padlock with a stainless steel shackle in a US4 satin brass finish, so the key comes out in either position and the body is solid brass rather than aluminum. The American Lock A1166 uses a 1-1/2 inch wide anodized aluminum body with a corrosion resistant finish and a 1/4 inch chrome plated boron shackle. Brass and stainless on the 858 is the common exterior gate build; the A1166's anodized aluminum is the build used where lockout color coding matters.
16) Which padlock has a thicker shackle than the American Lock A1166?
Several brass-body padlocks run heavier shackles than the A1166's 1/4 inch. The Medeco 5260 in the 52 Series brass body carries a 7/16 inch shackle diameter in a satin chrome finish with M3 key technology. The Schlage KS23D/KS23F brass padlock and the Medeco 54515G XT electronic padlock both use a 5/16 inch shackle. All three take a larger hasp opening than the A1166's 1/4 inch shackle, which is sized for lockout hasps and breaker clamps.
17) Can I use the Medeco 54515G XT electronic padlock where I currently run American Lock A1166 padlocks?
Only if you are changing how the locks are controlled. The Medeco 54515G XT is an electronic indoor/outdoor padlock, non-key retaining, with a 5/16 inch shackle diameter and cylinder included, so access is managed through the XT electronic system rather than a mechanical bitting. The American Lock A1166 is a mechanical 6-pin rekeyable padlock, keyed different, with over 40,000 key changes and a 1/4 inch shackle. Sites that want audit trail and scheduled access move to the 54515G; sites keying padlocks to an existing mechanical system stay on the A1166.
18) What is the difference between the American Lock A1166 and the Sargent 82-856 for a high security opening?
The Sargent 82-856 is a non-key retaining padlock in the KESO Series with a 2 inch by 2 inch brass case and a stainless steel shackle, a larger and heavier body than the A1166's 1-1/2 inch aluminum. The American Lock A1166 is a 6-pin APTC14 rekeyable cylinder in an anodized aluminum body with a chrome plated boron alloy shackle for cut resistance. The 82-856 is the choice when the opening is specified for KESO keying; the A1166 is the choice when the requirement is a color-coded aluminum lockout body.
19) Is the ABUS T84MB/30 a substitute for the American Lock A1166 on equipment lockout?
No. The ABUS T84MB/30 Nautic is a black sleeve padlock with a 13/64 inch shackle diameter and a 1 17/64 inch body width, sold in a 3-pack, built as a marine and general utility lock. The American Lock A1166 has a 1-1/2 inch anodized aluminum body and a 1/4 inch chrome plated boron shackle, and is built for lockout tagout including food processing facilities. The T84MB/30's thinner shackle and narrower body are a different class of lock from an equipment lockout padlock.
20) Which padlock do I use if the lock has to be issued without keys to the holder?
The Sargent 858 and the Sargent 82-856 are both non-key retaining, and the Medeco 54515G is non-key retaining as well, so the key releases in either position. The American Lock A1166 is supplied keyed different and can be ordered with 0 keys per lock, 1 key per lock, the standard 2 keys per lock, 3 keys per lock, or 4 keys per lock, which is how lockout programs control how many keys leave with the padlock. Sargent's 758 is the key retaining option in that group.
21) Can I get a safety padlock with a chain attached so it does not get lost?
The A1166 is offered with a #40 sash chain, 9 inches long, zinc plated, or with no chain at all. The chain version tethers the lock to the hasp or the equipment so it stays at the point of isolation between lockouts instead of walking off in a toolbox.
22) Does the key stay in the American Lock A1166 while the lock is open?
That behavior is called key retaining, and it is what stops a worker from walking away leaving a lock hanging unlocked with the key in their pocket. Among ZenSupply's padlocks the retaining and non-retaining versions are called out explicitly on the Sargent line, the 758 being key retaining and the 858 non-key retaining. If key retention is a written requirement on your lockout procedure, specify against those.
23) How do American Lock A1166 padlocks pack, and what is the minimum for a facility rollout?
Shelf pack is 6 locks and the master carton is 24. If you are outfitting crews, ordering in multiples of 6 keeps whole shelf packs together, and a 24 count carton covers a typical department rollout in one box. Colors are ordered per color, so a mixed-color program is separate line items.
24) Is a boron shackle worth it over a standard steel one on a lockout lock?
Boron alloy is a harder shackle material than plain steel and resists bolt cutters better, which is why the A1166 pairs it with a light aluminum body: you get cut resistance at the shackle without a heavy steel lock hanging off a hasp. It is chrome plated on top of that, so it does not rust out in a wet area. For a purely administrative lockout where nobody is attacking the lock, the cut resistance is a bonus rather than the reason to buy.
