Schlage B520-086 626 – Frequently Asked Questions

1) Which Schlage locks does the B520-086 screw fit?
It is the OEM fastener for Schlage B250 PD and RD mechanical lock assemblies. If you are servicing a different Schlage series, the thread may match but the 2-1/4 inch length is sized for the B250 PD/RD build, so check the part number on the original screw.
2) Can a Corbin Russwin ML2000 screw pack be used in place of the Schlage B520-086?
No. The B520-086 is a Phillips oval head machine screw sized #10-32 x 2-1/4" made specifically for Schlage B250 PD/RD lock assemblies. The Corbin Russwin 429F31 and 433F77 are screw packets built for ML2000 escutcheons - the 433F77 for M and P escutcheons - so their thread sizes and lengths follow the ML2000 trim, not the B250 chassis. Fasteners for a mortise lock trim do not carry over to a Schlage B250 tubular deadbolt-style installation; order the OEM B520-086 for that lock.
3) I need a single loose screw for a mortise lock rather than a full pack - what are my options?
For individual fasteners, the Corbin Russwin 425F86-8 is a single flat screw in 8-32 x 3/8" for ML2000 mortise locks, and the Corbin Russwin 206F57-8 is a single combo screw for ML2000 strikes. The Schlage B520-086 is also an individual machine screw, #10-32 x 2-1/4" with a Phillips oval head, but it is matched to Schlage B250 PD/RD locks. Choose by which lock line is on the door - the thread sizes are not interchangeable.
4) My strike plate screws stripped out - is the B520-086 the right replacement?
The B520-086 is the OEM mounting screw for Schlage B250 PD/RD lock assemblies, not a strike fastener. If the stripped screws are in a strike, the Corbin Russwin 206F57-8 is a strike combo screw for ML2000 mortise locks. Match the replacement to the lock line installed on the door.
5) Why an oval head screw instead of a flat head on a B250 deadbolt?
The oval head gives a rounded, finished profile where the screw shows on the trim, and the Phillips recess holds a driver without camming out during install. Schlage specifies this head style for B250 PD/RD, so swapping in a flat head from the shop bin changes how the screw seats in the countersink.
6) Is the B520-086 screw suitable for commercial door hardware work?
Yes, it is a commercial-grade Schlage installation accessory, used for B250 PD/RD lock service in offices, schools, healthcare, hospitality, and multi-tenant buildings. Property managers standardizing on B250 hardware can stock it as a consumable for rekey and trim-swap work.
7) If I am standardizing fasteners across a building, does finish matter when choosing between the B520-086 and a Corbin Russwin screw pack?
It can. The Schlage B520-086 is offered in 605 bright brass, 613 oil rubbed bronze, and 626 satin chrome, so the exposed oval head can be matched to the lock trim on the door. The Corbin Russwin ML2000 screw packets, such as the 429F31 for N escutcheons, are catalogued by the escutcheon they serve rather than by a finish choice. Where screw heads are visible on the trim, specify the finish that matches the existing hardware.
