Schlage L583-485 – Frequently Asked Questions

1) What does the Schlage L583-485 handing screw actually do on an L Series mortise lock?
The L583-485 is the screw that sets the handing on a Schlage L Series mortise lock. On these locks the latchbolt orientation is field-changeable, and this screw holds the configuration so the lock stays in the left- or right-hand setup you set it to. It is an installation accessory, not a lock body part you would replace for wear.
2) I have a Corbin Russwin ML2000 mortise lock, not a Schlage. Can I use the L583-485?
No. The L583-485 is specific to Schlage L Series mortise locks. For ML2000 hardware the matching parts are Corbin Russwin's own, such as the 206F57-8 strike combo screw, the 425F86-8 flat screw in 8-32 x 3/8 inch, or the escutcheon screw packs 429F31 for the N escutcheon and 433F77 for M and P escutcheons.
3) Is there an equivalent handing screw for a Corbin Russwin ML2000 mortise lock instead of a Schlage L Series?
No - the Schlage L583-485 handing screw is made for Schlage L Series mortise locks built after April 1994 and should not be used in a different manufacturer's mortise case. For Corbin Russwin ML2000 mortise locks, the corresponding fasteners are sold under Corbin Russwin part numbers, including the 425F86-8 flat screw in 8-32 x 3/8 inch and the 206F57-8 strike combo screw. Match the screw to the lock case brand and series rather than to the job.
4) Is the L583-485 a genuine Schlage part or an aftermarket screw?
Genuine Schlage OEM. The L583-485 is the factory handing screw for the L Series, made to Schlage's own tolerances, which matters here because a generic screw of the right diameter will not necessarily hold the handing position correctly.
5) Do I need to replace the whole Schlage mortise lock if the handing screw is stripped or missing?
No. The L583-485 is sold on its own as a screw pack so you can rehand or repair an existing L Series lock without pulling and replacing the complete lockset. That is the usual call for a facilities team standardizing on L Series across a building.
6) What should I order if I need the escutcheon mounting screws rather than the handing screw for a mortise lock?
The Schlage L583-485 is a handing screw - it sets left- or right-hand configuration inside the lock case, not the trim. If the need is trim mounting hardware on a Corbin Russwin ML2000, the escutcheon screw packs are separate items: the 429F31 screw packet is for the N escutcheon and the 433F77 screw pack is for M and P escutcheons. Confirm the escutcheon letter before ordering, since the packs are not interchangeable between escutcheon styles.
7) A generic screw pack is listed for mortise locks - can I use it in place of the Schlage handing screw?
A screw pack sold for mortise lock trim, such as the Corbin Russwin 433F77 for M and P escutcheons or the 429F31 for the N escutcheon, contains trim mounting fasteners and is not a substitute for the Schlage L583-485. The L583-485 is a single-purpose OEM handing screw that maintains the handing configuration and operation of an L Series mortise lock; a trim screw pack does not perform that function in the lock case.
8) Is this screw suitable for commercial building maintenance, or is it a residential part?
It is a commercial-grade part. The L Series is Schlage's commercial mortise line, and the L583-485 is the handing screw stocked for that line, typically used by locksmiths and facilities teams servicing offices, schools, healthcare and government buildings.
9) For a commercial retrofit, do I need a separate strike screw as well as the handing screw?
They are separate parts. The Schlage L583-485 addresses handing inside the L Series mortise case only; strike plate fastening is its own item, the way the Corbin Russwin 206F57-8 strike combo screw serves the ML2000 strike. If the retrofit involves both rehanding the lock and replacing strike hardware, plan on ordering the handing screw and the strike fastener for the matching lock brand separately.
