Schlage C604-052 – Frequently Asked Questions

1) Will the Schlage C604-052 screw pack work on any mortise cylinder, or only the 20-033?
Only the 20-033 Corbin Wood Products Mailbox Non-Modular Mortise Cylinder. Schlage builds the C604-052 specifically for that assembly, so treat it as a dedicated part rather than a general-purpose cylinder screw kit. If you are servicing a different cylinder or lock body, source the screw pack listed for that product instead.
2) Can a Corbin Russwin ML2000 screw pack be used in place of the Schlage C604-052?
No. The Schlage C604-052 screw pack is built for the 20-033 Corbin Wood Products Mailbox Non-Modular Mortise Cylinder, and its fasteners match that cylinder's original screw specification. The Corbin Russwin ML2000 screw packs, such as the 429F31 for the N escutcheon and the 433F77 for M and P escutcheons, are packaged for mortise lock escutcheon trim on the ML2000 series, not for a mailbox mortise cylinder. They serve different assemblies and are not interchangeable.
3) Do I need to order anything else with the C604-052, or is this just the screws?
Just the fasteners. The C604-052 is an installation accessory, so it does not include the cylinder, cam, or keys. If the 20-033 cylinder itself is damaged or you are rekeying, order the cylinder separately and use this pack only to replace missing or stripped mounting screws.
4) How do I make sure I order the correct Schlage screw pack the first time?
Order by model number C604-052 and confirm the cylinder you are servicing is the 20-033 Corbin Wood Products Mailbox Non-Modular Mortise Cylinder. Schlage uses part-specific screw packs, so the model number on the bag is the only reliable way to match it. There is a single version of C604-052, so there are no finish or length options to choose between.
5) If I only need one or two loose screws rather than a full pack, what are my options?
The Schlage C604-052 is sold as a screw pack for the 20-033 mailbox mortise cylinder, so it comes as a set rather than individual fasteners. If your repair is on a Corbin Russwin ML2000 and you need a single fastener, individual screws exist in that line: the 425F86-8 is a flat screw in 8-32 x 3/8 inch, and the 206F57-8 is a strike combo screw. Those are ML2000 parts and will not substitute into the mailbox cylinder assembly.
6) What is the difference between the Schlage C604-052 and the Corbin Russwin 206F57-8?
The C604-052 is a Schlage-supplied screw pack matched to the 20-033 Corbin Wood Products Mailbox Non-Modular Mortise Cylinder, and it is a commercial-grade installation accessory. The Corbin Russwin 206F57-8 is a single strike combo screw for the ML2000 mortise lock line. One fastens a mailbox cylinder assembly, the other fastens strike hardware on a mortise lock, so the choice is driven entirely by which assembly you are working on.
