Schlage B502-942 – Frequently Asked Questions

1) What is the Schlage B502-942 cam screw actually used for?
It is the screw that retains the cam on a Schlage 20-030 Dura Steel Mailbox non-modular mortise cylinder, in lengths up to 1-3/8 inches. If you are rebuilding or re-keying mailbox cylinders and the cam screw is stripped, missing, or you are changing a cam, this is the fastener that holds the cam to the back of the cylinder.
2) Will the B502-942 work with Everest or Primus cylinders?
Yes. The cam screw is compatible with Schlage Everest and Primus cylinder platforms, so it covers both standard Everest keyway mailbox cylinders and Primus high-security cylinders used in the same 20-030 Dura Steel application.
3) Can a Corbin Russwin ML2000 screw pack be used in place of the Schlage B502-942 cam screw?
No. The Schlage B502-942 is a cam screw made specifically to retain the cam on a 20-030 Dura Steel Mailbox non-modular mortise cylinder up to 1-3/8 inch, on Schlage Everest and Primus cylinder platforms. The Corbin Russwin 429F31 is a screw packet for the ML2000 N escutcheon, and the Corbin Russwin 433F77 is a screw pack for ML2000 M and P escutcheons - both are trim mounting hardware for a different manufacturer's mortise lock body, not cylinder cam screws. For cam retention on a Schlage cylinder, stay with the B502-942.
4) Can I buy just one or two of these cam screws?
No. The B502-942 is sold as a screw pack in multiples of 100, so it is a bulk item aimed at locksmiths, mailroom hardware programs, and maintenance shops stocking spares rather than a single-repair purchase.
5) Does the B502-942 pack include the cam itself?
No. This is the cam screw only, supplied as a screw pack. If your cylinder needs a different cam for the mailbox lock, order the cam separately along with these screws.
6) What is the difference between a cam screw like the Schlage B502-942 and a strike screw?
They fasten different parts of the opening. The B502-942 is a cam screw - it holds the cam to the back of a mortise cylinder so the cylinder can throw the lock, and it is specified for the 20-030 Dura Steel Mailbox non-modular cylinder up to 1-3/8 inch. A strike screw such as the Corbin Russwin 206F57-8 combo screw secures the strike plate in the frame on an ML2000 opening. Ordering one when you need the other leaves the job unfinished.
7) Is a generic 8-32 flat screw an acceptable substitute for the Schlage B502-942?
Not for cam retention. A flat screw such as the Corbin Russwin 425F86-8, an 8-32 by 3/8 inch flat screw for the ML2000, is a general fastener sized for that lock's own assembly. The B502-942 is dimensioned for cam attachment on the Schlage 20-030 Dura Steel Mailbox non-modular mortise cylinder up to 1-3/8 inch, with Everest and Primus cylinders, where head profile and length determine whether the cam seats and the cylinder turns freely.
8) Is the B502-942 a genuine Schlage part or an aftermarket screw?
It is a genuine Schlage installation accessory, model B502-942, built to Schlage's commercial hardware spec. That matters on cam screws because the thread and head must match the cylinder plug exactly to seat the cam without binding the tailpiece.
9) Where would a property manager typically use these screws in a building?
Mailbox and mailroom hardware. Typical uses are multi-tenant residential and apartment mailbox banks, commercial office building mailbox systems, school mailrooms, and government or municipal mail facilities, wherever Schlage 20-030 Dura Steel mailbox mortise cylinders are installed and cylinders get swapped or re-keyed between tenants.
