Schlage L583-454 – Frequently Asked Questions

1) What is the equivalent case cover screw if the mortise lock is a Corbin Russwin ML2000 instead of a Schlage L Series?
The Schlage L583-454 screw pack is made for Schlage L Series mortise lock cases and is not intended for other manufacturers' lock bodies. For a Corbin Russwin ML2000 mortise lock, the parallel fastener is the Corbin Russwin 425F86-8, a Grade 1 ML2000 flat screw in 8-32 x 3/8 inch. Match the screw to the lock body brand rather than assuming mortise case fasteners interchange.
2) Will a mortise escutcheon screw pack work in place of a lock case cover screw?
No. The Schlage L583-454 is a case cover screw that closes the mortise lock case itself. Escutcheon screw packs, such as the Corbin Russwin 429F31 for the ML2000 N escutcheon or the Corbin Russwin 433F77 for ML2000 M and P escutcheons, fasten the trim plate to the door and are a different fastener group. Ordering an escutcheon pack will not get the lock case buttoned back up.
3) Is the L583-454 a single screw or a pack?
It ships as a screw pack, which is how Schlage supplies these service fasteners. That makes it practical for a locksmith or maintenance shop to keep on the truck rather than ordering one screw per service call.
4) Does the L583-454 include anything else needed to reassemble an L Series lock case?
No. This is the case cover screw only. Trim screws, spindles, cylinder retaining parts, and strike fasteners are separate Schlage L Series part numbers, so order those alongside it if the lock came apart further than the cover.
5) I need screws for the strike, not the lock case - what should I order instead?
The Schlage L583-454 is an installation accessory for the L Series lock case cover, so it is the wrong part for strike work. For strike fasteners on a Corbin Russwin ML2000 opening, the Corbin Russwin 206F57-8 is a Grade 1 strike combo screw. Keep case cover screws and strike screws as separate line items when stocking a service van.
6) Is this a commercial-grade part or a residential one?
Commercial. The L583-454 belongs to Schlage's commercial mortise lock line, which is what goes into offices, schools, hospitals, government buildings, and multi-tenant residential corridors. It is a service fastener for that hardware, not a light-duty residential screw.
7) I manage a building with Schlage L Series locks on every door. Is it worth stocking this screw?
If your doors are standardized on Schlage L Series mortise locks, yes. The case cover screw is one of the small parts that goes missing during a service call, and the pack format is meant for exactly that kind of shelf stock for facilities teams and technicians.
8) Is there a difference between buying a single screw and a screw pack for mortise lock service?
The Schlage L583-454 is supplied as a screw pack, which suits technicians restocking for repeated L Series service calls. Some comparable mortise fasteners are sold as individual screws, such as the Corbin Russwin 425F86-8 flat screw and the Corbin Russwin 206F57-8 strike combo screw, while the Corbin Russwin 429F31 and 433F77 are supplied as packs. Choose the format that matches whether you are fixing one opening or stocking for a building.
