Schlage B520-484 – Frequently Asked Questions

1) What does the Schlage B520-484 cam screw actually do in a mortise lock?
The B520-484 is the screw that holds the cam on a Schlage L Series non-modular mortise small format interchangeable core cylinder. It retains the cylinder and keeps the cam aligned so the core turns the lock case correctly. If a cam is loose, spinning, or missing its screw after a core swap, this is the part you replace.
2) Will the B520-484 work with Schlage L Series modular mortise cylinders?
No. The B520-484 is specified for L Series NON-modular mortise SFIC cylinders. Modular mortise cylinders use different cam hardware, so confirm your cylinder is the non-modular SFIC type before ordering this screw.
3) Can a Corbin Russwin ML2000 screw pack be used in place of the Schlage B520-484 cam screw?
No. The Schlage B520-484 is a cam screw made specifically for Schlage L Series Non-Modular Mortise SFIC cylinders, where it retains the cylinder cam in correct alignment. The Corbin Russwin parts in the same family serve the ML2000 mortise lock instead: the 429F31 is a screw packet for the N escutcheon and the 433F77 is a screw pack for M and P escutcheons. Those fasten trim to the lock body, not a cylinder cam, so they are not a functional stand-in for the B520-484.
4) Is this a genuine Schlage part or an aftermarket screw?
Genuine Schlage. The B520-484 is an OEM cam screw made to Schlage tolerances for L Series mortise SFIC cylinders, which matters here because the cam and screw thread fit is tight and a generic machine screw can leave the cam loose.
5) Do I need anything else to install a Schlage L Series mortise SFIC cylinder besides this cam screw?
The B520-484 covers only the cam retention screw. The cylinder housing, the interchangeable core, the cam itself, and the control key for pulling the core are separate items. Order this when the screw is what is missing or stripped, not as a complete cylinder kit.
6) My ML2000 strike is loose at the frame. Does the Schlage B520-484 cover that?
No. The B520-484 is a cylinder cam screw for Schlage L Series Non-Modular Mortise SFIC applications and has nothing to do with strike mounting. For a loose Corbin Russwin ML2000 strike, the 206F57-8 is the strike combo screw for that lock.
7) Is the Schlage B520-484 rated for commercial door hardware use?
Yes, it is a commercial-grade part, catalogued for commercial rather than residential mortise lock service. Typical users are schools, hospitals, offices, and government buildings running Schlage L Series mortise SFIC hardware.
8) Is the B520-484 a single screw or a packet of fasteners?
The B520-484 is catalogued as a screw pack supplying the cam screw used to retain a Schlage L Series Non-Modular Mortise SFIC cylinder cam. Among the comparable Corbin Russwin fasteners, the 429F31 and 433F77 are likewise screw packs, while the 425F86-8 is identified as an individual flat screw at 8-32 x 3/8 inch and the 206F57-8 as a strike combo screw. If you need a stated thread and length for an individual fastener, the 425F86-8 is the one in this group that publishes it.
