Corbin Russwin 438F41-8 – Frequently Asked Questions

1) What is the difference between the Corbin Russwin mortise cylinder cam screw and the IC mortise cylinder cam screw?
Two versions of the Corbin Russwin 438F41-8 cam screw are offered: one for standard mortise cylinders and one for interchangeable core (IC) mortise cylinders. Pick based on the cylinder already in the lock. If the cylinder takes a removable core with a control key, order the IC version; if it is a conventional fixed-pin mortise cylinder, order the standard mortise cam screw.
2) My key turns but the mortise lock does not operate. Do I need a new cylinder or just the cam screw?
A key that rotates freely without moving the latch or bolt usually means the cam is no longer being driven, and a loose or missing cam screw is a common cause. On Corbin Russwin mortise cylinders the 438F41-8 cam screw lets a locksmith or maintenance tech reseat the cam and restore function without buying a whole new cylinder or lockset.
3) Will this cam screw work on a residential mortise lock or any brand of cylinder?
No. The 438F41-8 is a commercial part built for Corbin Russwin mortise cylinders only. Cam screws are not interchangeable across manufacturers, so a Schlage, Best or Yale mortise cylinder needs that brand's own cam screw. If the cylinder in your door is not Corbin Russwin, this is the wrong part.
4) Is the Corbin Russwin 438F41-8 cam screw a genuine OEM part or aftermarket?
It is a genuine Corbin Russwin replacement part, made to the manufacturer's own specification for their mortise cylinders. That matters on a cam screw because thread pitch and head profile have to match the cam and cylinder body exactly for the cam to seat flush behind the lock case.
5) We standardize on Corbin Russwin across our buildings. Is this a good part to stock for maintenance?
Yes, it is a sensible shelf item for facilities running Corbin Russwin mortise hardware. The cam screw is a low-cost consumable that comes loose during rekeying and cylinder swaps, and having both the standard and IC versions on the truck means a tech can finish the call instead of pulling a working cylinder off another door. It suits office buildings, schools, healthcare, retail, government and multi-tenant residential portfolios.
6) Does using this cam screw affect the ANSI/BHMA Grade 1 rating of my Corbin Russwin mortise lock?
Corbin Russwin mortise locks sit in an ANSI/BHMA Grade 1 hardware line, and this is the factory cam screw for those cylinders. Using the OEM screw keeps the cylinder assembly as originally built, which is what a spec-driven institutional job typically requires rather than a generic hardware-store fastener.
