Adams Rite S281-06R05-603-MP – Frequently Asked Questions

1) What size screws come in the Adams Rite S281-06R05-603-MP pack?
Ten #6-32 x 5/16 inch flat head machine screws, in a 603 zinc plated finish. The #6-32 is a machine thread, not a wood screw, so it threads into a tapped hole in the lock case or trim rather than biting into the door itself.
2) I'm short a couple of screws on an Adams Rite lock service call. Is this the right replacement?
If the fastener you lost is a #6-32 x 5/16 flat head, yes. The pack is sold as a genuine Adams Rite replacement and installation accessory for its mechanical lock hardware, so thread pitch and head profile match the factory fastener. Pull one of the remaining screws from the assembly and check thread and length against #6-32 x 5/16 before you order, since Adams Rite uses several fastener sizes across its line.
3) Will Adams Rite S281 screws work on a Corbin Russwin ML2000 lock?
No. The S281 pack is an Adams Rite fastener at #6-32 x 5/16. Corbin Russwin's ML2000 uses its own fasteners, for example the 425F86-8 flat screw at 8-32 x 3/8 inch, a heavier thread and a longer screw. For ML2000 escutcheon work Corbin Russwin also supplies dedicated screw packets, the 429F31 for the N escutcheon and the 433F77 for M and P escutcheons.
4) Is the Corbin Russwin 425F86-8 flat screw a direct replacement for the Adams Rite S281-06R05-603-MP?
No. The Adams Rite S281-06R05-603-MP is a #6-32 x 5/16 inch flat head screw supplied 10 to a pack, while the Corbin Russwin 425F86-8 is an 8-32 x 3/8 inch flat screw for ML2000 mortise locks. The thread diameter and pitch differ, so the 8-32 screw will not thread into a hole tapped for #6-32. Match the Adams Rite part when you are servicing Adams Rite mechanical door hardware.
5) What screw pack should I order for a Corbin Russwin ML2000 escutcheon instead of the Adams Rite S281 pack?
For Corbin Russwin ML2000 mortise locks, use the ML2000 escutcheon screw packs: the 433F77 covers M and P escutcheons and the 429F31 covers the N escutcheon. The Adams Rite S281-06R05-603-MP screw pack is intended as a genuine Adams Rite installation accessory for Adams Rite mechanical lock assemblies, so it is the wrong family for an ML2000 trim.
6) Will a #6-32 x 5/16 inch flat head screw sit flush in countersunk hardware?
That is what the flat head profile is for. The countersunk head pulls down level with a chamfered hole, so trim plates and covers finish flush instead of standing proud. If the hole in your part is not countersunk, a flat head will not seat and you want a pan or truss head instead.
7) I need screws for a strike rather than a lock body - is the Adams Rite S281 pack the right part?
The Adams Rite S281-06R05-603-MP is a #6-32 x 5/16 inch flat head screw pack for Adams Rite mechanical lock assemblies. If you are fastening a strike on a Corbin Russwin ML2000 opening, the 206F57-8 is the strike combo screw for that system. Confirm which component you are securing before ordering, since the two are not interchangeable.
8) Is this screw pack meant for commercial door hardware or residential locks?
Commercial. Adams Rite lists the S281-06R05-603-MP as a commercial installation accessory for its mechanical lock hardware, the kind of parts used in offices, retail, schools, healthcare, and multi-tenant buildings.
9) Does the 603 zinc plated finish matter if my door hardware is a different finish?
Functionally no, cosmetically sometimes. The only finish offered on the S281-06R05-603-MP is 603 zinc plated, a bright silver-tone plating. Because the head is countersunk and sits flush, it is largely hidden on most trim; where the screw head will be visible against a dark or brass finish, expect it to show.
10) How many screws do I get, and is one pack enough to do several doors?
Ten screws per pack. That covers a single install plus spares, or small fastener replacements across a few openings. If you are standardizing an Adams Rite fastener across a building's worth of doors, count the screws per assembly and multiply, since one pack of 10 goes quickly on multi-screw trim.
11) What is the difference between ordering a single screw part and a screw pack like the Adams Rite S281?
The Adams Rite S281-06R05-603-MP is supplied as a pack of 10 #6-32 x 5/16 inch flat head screws, which covers installation and service on multiple units. Corbin Russwin offers both approaches for ML2000: the 425F86-8 is catalogued as a flat screw and the 429F31 and 433F77 are screw packets for the N and for the M and P escutcheons. Choose the pack format when you are stocking a service van or standardizing spares across a facility.
