Schlage 09-493 604 – Frequently Asked Questions

1) What locks do the Schlage 09-493 mounting screws fit?
The 09-493 screw pack is made for Schlage L Series commercial mortise locks, and is catalogued by Schlage as part L583-066. It is a genuine Schlage fastener, so it matches the tapped holes and torque requirements of the L Series lock case and trim rather than being a generic hardware-store screw.
2) I need mortise lock mounting screws but my locks are Corbin Russwin, not Schlage. Will the 09-493 work?
No. The 09-493 is cut for the Schlage L Series and should not be substituted into another manufacturer's mortise lock. For Corbin Russwin ML2000 mortise locks, ZenSupply carries the matching Corbin parts: the 429F31 screw packet for the N escutcheon, the 433F77 screw pack for M and P escutcheons, the 425F86-8 flat screw in 8-32 x 3/8 inch, and the 206F57-8 strike combo screw.
3) What is the Corbin Russwin equivalent of the Schlage 09-493 mounting screw pack?
For Corbin Russwin ML2000 mortise locks, the closest counterparts are the 429F31 screw packet for the N escutcheon and the 433F77 screw pack for M and P escutcheons, both Grade 1 ML2000 screw packs. The Schlage 09-493 (L583-066) is a 100-pack of mounting screws made for Schlage L Series mortise locks, so the two families are not interchangeable - the Corbin Russwin packs are matched to specific ML2000 escutcheon trims, while the 09-493 is a bulk fastener pack for L Series lock assemblies.
4) How many screws come in the Schlage 09-493 pack?
One hundred screws per pack. That bulk count suits a locksmith or facilities crew servicing L Series mortise locks across a building, where a single box covers a run of installs and leaves spares on the shelf instead of ordering per door.
5) I need just a few screws, not 100 - what are my options?
The Schlage 09-493 is sold as a 100-pack, which suits installers and maintenance shops stocking spares across many L Series mortise locks. If you are working on Corbin Russwin ML2000 hardware instead and need a single fastener rather than a bulk pack, individual items exist in that line, such as the 425F86-8 flat screw in 8-32 x 3/8 inch and the 206F57-8 strike combo screw. These are ML2000 parts and do not substitute into a Schlage L Series lock.
6) Can I use the Schlage 09-493 screws to fasten a mortise lock strike?
The 09-493 pack is mounting screws for Schlage L Series mortise lock assemblies. Strike fastening is a separate part in mortise lock lines - on the Corbin Russwin side, for example, the 206F57-8 is specifically a strike combo screw for ML2000. Order the strike-specific fastener for your lock brand rather than assuming a lock mounting screw will seat correctly in strike prep.
7) Will these Schlage screws hold up in a damp or high-traffic commercial environment?
The finish is zinc with a dichromatic sealed treatment, which is a corrosion-resistant plating intended for commercial door hardware service. The screws are classified as commercial rather than residential hardware, and typical use runs to offices, schools, healthcare, government buildings, retail, warehouses, and multi-tenant residential.
8) What finish option does the Schlage 09-493 screw pack come in?
The pack is offered in 604 Satin Brass as the ordering finish, with the screws themselves in Schlage's zinc dichromatic sealed plating. For most L Series installs the screw heads sit under trim or in the lock case, so the plating matters more for corrosion resistance than for appearance matching.
9) Is the 09-493 a replacement part or something included with a new lock?
It is sold as a standalone installation accessory, useful both for restocking lost or stripped fasteners during service calls and for shops that install L Series mortise locks in volume and want screws on hand. It contains screws only, no lock case, trim, or strike.
10) What is the difference between a screw pack and a single screw part number when ordering mortise lock fasteners?
A screw pack supplies a set of fasteners in one part number - the Schlage 09-493 holds 100 mounting screws for L Series locks, and Corbin Russwin 429F31 and 433F77 are ML2000 screw packets tied to particular escutcheon trims. A single-screw part number covers one specific fastener, such as the Corbin Russwin 425F86-8 flat screw at 8-32 x 3/8 inch. Packs suit stocking and full installs; single part numbers suit replacing one lost or stripped fastener.
