Adams Rite SETSCREW 7/8 – Frequently Asked Questions

1) Will these Adams Rite set screws work with an MS cam mortise cylinder?
Yes. The Adams Rite mortise locks these screws serve accept standard Adams Rite MS cam mortise cylinders, so if you're swapping or rekeying an MS cam cylinder in a 7/8 inch backset lock, the S232B8-9/32N-631-MP is the retaining screw for that assembly.
2) Are these set screws right for narrow stile aluminum storefront doors?
That's exactly the application. Adams Rite 7/8 inch backset mortise locks are narrow stile aluminum door hardware, and this screw is the cylinder retainer for that lock. The 7/8 inch backset is the giveaway: that shallow a backset only exists because an aluminum stile has no room for the 2-3/8 or 2-3/4 inch backsets used on wood and hollow metal doors.
3) My mortise lock has a 1-1/8 inch backset, are these the same screws?
Order against your backset, not by eye. The S232B8-9/32N-631-MP is specified for 7/8 inch backset Adams Rite mortise locks. Measure from the face of the stile to the center of the cylinder hole and confirm 7/8 inch before ordering. Adams Rite builds mortise locks in several backsets for different stile widths, and the set screw is called out per backset.
4) What does the set screw actually do in an Adams Rite mortise lock?
It retains the cylinder. The S232B8 set screws hold the mortise cylinder in the lock case so it can't back out or be turned free, which is what keeps the lock operating securely. Lose one during a cylinder change and the cylinder is no longer positively retained, which is why they're a standard replacement part on aluminum storefront service work.
5) How many bags of Adams Rite S232B8 set screws do I need for a 12 door service call?
Two screws go into each mortise lock assembly, and the S232B8-9/32N-631-MP comes 10 to a bag. Twelve locks need 24 screws, so three bags. Locksmiths carrying these on the truck usually take an extra bag, since set screws are the piece that walks off during a cylinder swap.
6) I need a cylinder collar, not a set screw, what should I be looking at?
Different part. The S232B8 is the screw that locks the cylinder into the mortise case. If the gap you're filling is between the cylinder face and the door, that's a collar or spacer ring, and ZenSupply carries the GMS KIT-PART04 collars kit for that. Buy both if you're doing a cylinder change on a storefront door and don't know yet how far the cylinder sits proud.
7) Is this a commercial grade part or is it for residential locks?
Commercial. The S232B8 set screw is a commercial door hardware component, used on storefront and institutional openings, glass aluminum entrances, retail, office, education and healthcare facilities. It isn't a residential lock part.
8) Can I use an Adams Rite set screw with an electric strike setup?
Yes, nothing about the screw changes. The 7/8 inch backset mortise locks it serves work with Adams Rite electric strikes for access control, and the set screw's only job is holding the cylinder in the lock body. The strike is a separate frame side component. If you're working a glass door lock instead of an aluminum stile mortise lock, the strike hardware is its own item, for example the Codelocks CL4000 glass door strike box for CL4000 and CL4500 glass door locks.
9) Do these set screws come in different finishes to match my lock?
Set screws seat below the surface, so finish rarely shows on the installed job. The Adams Rite mortise locks in this family are offered in US3, US4, US10B, US32 and US32D. Order the screw by backset, 7/8 inch, and match the visible finish on the lock face and cylinder collar instead.
10) Which doors do Adams Rite 7/8 inch backset mortise locks go on besides aluminum?
Primarily narrow stile aluminum, and hollow metal and wood door options are offered in the family as well. The set screw itself is tied to the lock, not the door material, so once you've confirmed a 7/8 inch backset Adams Rite mortise lock, the S232B8 is the retainer regardless of what the door is made of.
11) Are these Adams Rite set screws made by ASSA ABLOY?
Adams Rite is an ASSA ABLOY Group brand, so the S232B8-9/32N-631-MP is genuine manufacturer hardware rather than an aftermarket screw. For a facility standardizing on Adams Rite storefront locks, that matters: the screw is cut to the same thread and length the lock case was tapped for.
