Schlage C604-226 – Frequently Asked Questions

1) Which Schlage mailbox cylinders does the C604-226 screw pack fit?
The C604-226 screw pack is made for Schlage 20-033, 20-066, 20-067, and 20-069 mailbox cylinders. If your cylinder is one of those four, this is the correct mounting hardware pack. It is not a universal mailbox screw kit, so a cylinder outside the 20-series numbers listed will not be covered by it.
2) I'm replacing a mailbox cylinder in an apartment building - do I need to order the screw pack separately?
Yes, the C604-226 is sold as its own part. It is the installation hardware for Schlage 20-033, 20-066, 20-067 and 20-069 mailbox cylinders, so if the screws that came out of the old cylinder are stripped, lost, or the wrong length, order this pack alongside the cylinder. Property managers servicing a bank of boxes often keep a few on the shelf for exactly that reason.
3) Can a Corbin Russwin ML2000 screw pack be used in place of the Schlage C604-226 on a mailbox cylinder?
No. The Schlage C604-226 screw pack is built for Schlage 20-033, 20-066, 20-067 and 20-069 mailbox cylinders. The Corbin Russwin 429F31 and 433F77 are screw packets for ML2000 mortise lock escutcheons - the 429F31 for the N escutcheon and the 433F77 for the M and P escutcheons. They serve mortise lock trim, not a mailbox cylinder assembly, so they are not interchangeable with the C604-226.
4) Is the Schlage C604-226 a genuine OEM part or an aftermarket screw kit?
It is a genuine Schlage replacement component, part of Schlage's own parts and accessories line, machined to Schlage tolerances so the cylinder seats correctly in the mailbox door. For institutional and government mail facilities that specify OEM-only replacement parts, that matters on the paperwork as much as on the door.
5) How many parts do I get when I order the Schlage C604-226?
The C604-226 is ordered as a single screw pack under one SKU, with no finish, size, or length options to pick. One line item gets you the fastener set for one compatible mailbox cylinder installation, so order one pack per cylinder you are servicing.
6) What is the difference between a screw pack like the Schlage C604-226 and an individual screw part number?
A screw pack supplies the full set of fasteners for one assembly - the Schlage C604-226 covers Schlage 20-033, 20-066, 20-067 and 20-069 mailbox cylinders, and the Corbin Russwin 429F31 and 433F77 are packs for ML2000 escutcheons. Individual part numbers cover a single fastener instead: the Corbin Russwin 425F86-8 is an ML2000 flat screw in 8-32 x 3/8 inch, and the 206F57-8 is a strike combo screw for the ML2000. Order a pack when you are servicing or replacing the whole assembly, and the single screw number when you are replacing one lost or stripped fastener.
7) Is the Schlage C604-226 an option for replacing a mortise lock strike screw?
No. The C604-226 is a Schlage installation accessory for 20-series mailbox cylinders. For a mortise lock strike fastener, the Corbin Russwin 206F57-8 is the Grade 1 strike combo screw for the ML2000 series.
8) Is this screw pack rated for commercial use or is it a residential-grade part?
Schlage lists the C604-226 as a commercial part. Typical use is multi-unit residential mailbox banks, office building mail centers, institutional mailrooms and municipal mail facilities, where the same cylinder gets keyed and re-keyed repeatedly over its life.
