Schlage L583-481 – Frequently Asked Questions

1) Will the L583-481 fit an older Schlage L Series mortise lock?
Only if the lock was built after April 1994. Schlage changed the cylinder retention on the L Series, and the L583-481 is specified for post-April-1994 lock bodies. For an older case you need the earlier retainer screw, not this one. If you are unsure of the age, pull the lock and check the retainer arrangement before ordering.
2) I have Corbin Russwin ML2000 mortise locks, not Schlage. Can I use the L583-481?
No. The L583-481 is cut to the Schlage L Series case tapping and will not serve an ML2000. For Corbin Russwin ML2000 hardware, ZenSupply carries the matching fasteners in that line, including the 425F86-8 flat screw (8-32 x 3/8 inch), the 206F57-8 strike combo screw, the 429F31 screw packet for the N escutcheon, and the 433F77 screw pack for M and P escutcheons.
3) Is there a Corbin Russwin equivalent to the Schlage L583-481 cylinder retainer screw for a mortise lock?
Not a direct one. The Schlage L583-481 is a cylinder retainer screw made for Schlage L Series mortise locks manufactured after April 1994, and it retains the mortise cylinder inside the L Series lock body. Corbin Russwin's mortise screw parts are built around the ML2000 mortise lock instead: the 429F31 is an ML2000 screw packet for the N escutcheon and the 433F77 is an ML2000 screw pack for M and P escutcheons. Those are trim-mounting screw packs for a different lock body, so if the lock in the door is a Schlage L Series, order the L583-481 rather than an ML2000 part.
4) Is this sold as a single screw or a pack?
It ships as a screw pack, which is how Schlage packages these service fasteners. That format suits MRO and facilities buyers stocking a parts bin for a building full of L Series mortise locks rather than chasing one screw at a time.
5) My mortise lock trim screws are stripped. Is the cylinder retainer screw the right replacement?
Probably not. The L583-481 retains the cylinder inside the case, not the escutcheon, rose or lever trim to the door. If what is loose is the trim or the strike, you want the corresponding trim or strike fastener for your lock line, the way the Corbin Russwin side splits into a strike combo screw and separate escutcheon screw packs.
6) Can I use a loose 8-32 x 3/8 inch flat screw in place of the Schlage L583-481?
They are not the same part. The Corbin Russwin 425F86-8 is an individual ML2000 flat screw in 8-32 x 3/8 inch, sold as a single flat screw for that mortise lock. The Schlage L583-481 is a genuine OEM screw pack whose job is retaining the mortise cylinder in a Schlage L Series lock body built after April 1994, machined to Schlage's own specification for that seat. Substituting a generic flat screw risks improper cylinder alignment, so use the L583-481 on L Series work.
7) Is the Schlage L583-481 the same kind of part as a mortise strike combo screw?
No. A strike screw fastens the strike plate to the frame; the Corbin Russwin 206F57-8 is a combo screw for the ML2000 strike and lives on the jamb side of the opening. The Schlage L583-481 works inside the lock case, holding the mortise cylinder in place on Schlage L Series locks made after April 1994. If the problem is a loose or spinning cylinder, the L583-481 is the part; if the strike is loose in the frame, look to a strike screw.
8) Is the L583-481 rated for commercial door traffic or is it a residential part?
Commercial. The L Series is a commercial mortise lock line and this retainer screw is catalogued as commercial-grade hardware, used in offices, schools, healthcare, government buildings, retail, warehouses and multi-tenant residential.
9) For standardizing mortise lock repair parts across a facility, how does the Schlage L583-481 fit alongside Corbin Russwin ML2000 screw packs?
They cover different lock platforms, so most institutional stockrooms carry whichever matches the installed hardware. The Schlage L583-481 is a commercial-grade OEM screw pack for Schlage L Series mortise locks made after April 1994 and addresses cylinder retention. On the Corbin Russwin side, the ML2000 parts split by location: 206F57-8 for the strike, 425F86-8 as a flat screw, and the 429F31 and 433F77 screw packs for N and for M and P escutcheons. Survey which mortise bodies are in the doors first, then stock the retainer screw for the Schlage openings and the ML2000 packs for the rest.
