Metallics JG5N163D – Frequently Asked Questions
1) What wrench or socket size do I need for the Metallics JG5N163D 1/4-20 hex nut?
Across the flats the nut measures 0.423 to 0.438 inch, which is a 7/16 inch wrench or socket. Metallics notes that the stated width is the wrench size, so a 7/16 open end, box, or socket drives it without a wobble fit.
2) Will a 1/4-20 Grade 5 hex nut thread onto any standard 1/4 inch bolt?
It threads onto 1/4 inch bolts cut 20 threads per inch in UNC (coarse), right hand. It will not go onto a 1/4-28 UNF fine thread bolt, and it is not a metric M6. Confirm the bolt is coarse thread before ordering.
3) Do these Metallics nuts meet Buy American requirements for a government or institutional job?
Yes. The JG5N163D hex nuts are made in the United States and flagged Buy American compliant, which is what a federal, state, school, or healthcare procurement file usually needs on fastener line items.
4) Should I use a Grade 5 nut or a Grade 2 nut with my bolts?
Match the nut to the bolt. The JG5N163D is a Grade 5 nut at Rockwell C32 hardness, meant for use with bolts whose minimum tensile strength is equal to or less than the nut's specified proof stress. If you are torquing Grade 5 or Grade 8 bolts, a Grade 2 nut can strip before the joint is tight. For low-stress sheet metal or strut work with Grade 2 bolts, a Grade 2 nut is adequate and the Grade 5 is simply stronger than needed.
5) Is the zinc finish on these nuts suitable for outdoor or damp locations?
Zinc plated hardened steel is a mild corrosion coating, fine for indoor electrical rooms, panel work, and dry interior strut. Standing water, washdown, coastal air, or buried work will eventually rust it; for those conditions step up to a 18-8 or 316 stainless 1/4-20 hex nut instead.
6) What dimensional standard do these 1/4-20 hex nuts follow, and will they match nuts already on my job?
They are made to American Standard dimensions per ANSI/ASME B182.2, so they interchange with any other domestic 1/4-20 hex nut built to that standard. Nut thickness runs 0.212 to 0.226 inch and overall width 0.488 to 0.505 inch, which is standard hex nut geometry, not a thin or jam nut.
7) How many nuts come in a jar and can I buy fewer than 100?
They ship in a jar of 100, and 100 count is the order minimum, so a jar is the smallest buy. Metallics does offer other sizes and quantities by request if you need a different pack.
8) Is this a plain hex nut or does it have a nylon insert or flange?
Plain finished hex nut, zinc plated steel, silver in color. No nylon locking insert, no flange, no serrations. If vibration is a concern on your assembly you will need to add a lock washer or specify a nylon insert lock nut separately.
9) What does a jar of 100 of these 1/4-20 nuts weigh for shipping or a stock cart?
A jar of 100 comes in at 0.75 lbs, with the jar itself listed at 3 x 3 x 2.15 inches. Small enough to keep several sizes on a van shelf without eating payload.
