Schlage 61-504 626 – Frequently Asked Questions

1) What locks does the Schlage 61-504 screw pack fit?
The 61-504 combination screw pack is made for Schlage B581 and B581/71 series mechanical locks. It is the fastener kit for those deadbolt installations, not a generic screw assortment, so it should not be substituted into other Schlage series.
2) Will the Schlage 61-504 screws work on a 1-3/4 inch commercial door?
Yes. The 61-504 pack covers doors from 1-3/8 to 1-3/4 inches thick, which spans the standard 1-3/4 inch commercial door and the thinner 1-3/8 inch interior door. If your opening is thicker than 1-3/4 inches, this pack is not the right screw length set.
3) What is the equivalent of the Schlage 61-504 screw pack if the building is standardized on Corbin Russwin ML2000 mortise locks?
For ML2000 trim, the matching fastener kits are the Corbin Russwin 429F31 screw packet for the N escutcheon and the Corbin Russwin 433F77 screw pack for M and P escutcheons; pick by the escutcheon style on the lock. The Schlage 61-504 fills the same role on the Schlage side, bundling the fasteners for B581 and B581/71 locks on 1-3/8 inch to 1-3/4 inch doors so an installer is not sourcing individual screws. If a facility runs both brands, stocking one pack per lock platform covers service calls on either.
4) Can a Corbin Russwin ML2000 screw pack be used in place of the Schlage 61-504 on a B581 installation?
No. The Schlage 61-504 is a combination screw pack built specifically for Schlage B581 and B581/71 mechanical locks on doors 1-3/8 inch to 1-3/4 inch thick, and it contains the B520-663, C603-897, B600-066 and B600-018 fasteners those locks use. The Corbin Russwin 429F31 is a screw packet for the ML2000 N escutcheon, and the Corbin Russwin 433F77 is a screw pack for ML2000 M and P escutcheons. Those are mortise lock escutcheon fasteners for a different lock body and trim, so the thread sizes and lengths are matched to the ML2000, not to a Schlage B-series deadbolt. Order the pack that matches the lock brand and series already in the door.
5) Exactly which screws come in the Schlage 61-504 pack and how many of each?
Four part numbers, seven pieces total: 2x B520-663, 4x C603-897, 2x B600-066 and 1x B600-018. If you only need one of those fasteners, you are still buying the full combination pack.
6) Do the 61-504 screws come in a finish that matches my lock?
Three finishes are offered: 605 bright brass, 613 oil rubbed bronze and 626 satin chrome. Order the one that matches the B581 trim already on the door so exposed heads blend in.
7) I only need one or two loose screws, not a full pack - is there a single-screw option instead of the Schlage 61-504?
The Schlage 61-504 is sold as a combination pack containing 2x B520-663, 4x C603-897, 2x B600-066 and 1x B600-018, so it is not broken down into individual fasteners. On the Corbin Russwin ML2000 side, individual fasteners are catalogued separately: the 206F57-8 is a strike combo screw and the 425F86-8 is a flat screw in 8-32 x 3/8 inch. Those are ML2000 parts and will not substitute into a Schlage B581 lock, but they show the difference between buying a single screw and buying a full installation kit.
8) Is the Corbin Russwin 206F57-8 a strike screw substitute for what comes in the Schlage 61-504?
No. The 206F57-8 is a Corbin Russwin strike combo screw for the ML2000 mortise lock, sold as a screw rather than a kit. The Schlage 61-504 is a combination pack of the fasteners used to mount B581 and B581/71 locks on 1-3/8 inch to 1-3/4 inch doors. The two are matched to different lock platforms, so a strike screw from an ML2000 should not be dropped into a Schlage B-series strike prep - use the fastener specified for the lock in the opening.
9) I manage a building with Schlage B581 deadbolts. Is this worth stocking for service calls?
That is the intended use. It is a commercial-grade installation accessory that bundles every fastener a B581/71 install needs into one pack, so a tech on a lock swap or reinstall is not hunting a single missing screw. Stock it in the finish that matches your standard trim.
10) Does the finish choice on the Schlage 61-504 matter when comparing it to other screw packs?
It does, because the exposed fasteners should match the lock trim. The Schlage 61-504 is offered in 605 bright brass, 613 oil rubbed bronze and 626 satin chrome so the screws blend with the B581 trim on the door. The Corbin Russwin ML2000 fastener items - the 429F31 N escutcheon screw packet and the 433F77 M and P escutcheon screw pack - are specified by escutcheon style for that lock platform. Match both brand and finish to the hardware already installed.
