Schlage B520-298 – Frequently Asked Questions

1) What does the anti-pry shield on this Schlage retainer screw actually do?
The shield on the B520-298 sits behind the cylinder retainer so the cylinder cannot be levered or twisted out of the lock body during a forced-entry attempt. If you replace the original with a plain machine screw of the same thread, the cylinder is still held but the pry resistance the lock was built with is gone. That matters most on exterior and tenant-entry doors.
2) Can a Corbin Russwin ML2000 screw pack be used in place of the Schlage B520-298 cylinder retainer screw?
No. The Schlage B520-298 is a #10-32 x 3/8 inch Phillips head machine cylinder retainer screw with an anti-pry shield, made to retain cylinders in Schlage B560/62/63 P, B562 GD/R, B600, B700, B800 and S200 Series locks. The Corbin Russwin 429F31 is a screw packet for the ML2000 N escutcheon, and the 433F77 is a screw pack for ML2000 M and P escutcheons. Those Corbin Russwin packs mount escutcheon trim on a mortise lock body rather than retaining a cylinder, and they are cut for the ML2000 chassis, not a Schlage B-Series cylinder. Order the B520-298 when the part being replaced is the cylinder retainer.
3) I need a 3/8 inch screw for a mortise lock - is the Corbin Russwin 425F86-8 the same thing as the Schlage B520-298?
They share a 3/8 inch length but not a thread or a head. The Schlage B520-298 is #10-32 x 3/8 inch with a Phillips head and an integrated anti-pry shield for cylinder retention. The Corbin Russwin 425F86-8 is an 8-32 x 3/8 inch flat screw for the ML2000. The 8-32 thread will not engage a Schlage cylinder retainer tap cut for #10-32, so the two are not interchangeable even though the lengths match.
4) I manage a building with a mix of Schlage B600 and B700 deadbolts. Can I stock one retainer screw for both?
Yes, one part covers both. The B520-298 is the common cylinder retainer screw across B600, B700 and B800 Series, and it also covers S200 Series and the B560/62/63 P and B562 GD/R locks. That makes it a single line item to carry for a mixed Schlage B-Series fleet rather than one screw per lock family.
5) If the screws that failed are at the strike rather than the cylinder, what should I order instead of the B520-298?
The Schlage B520-298 is a cylinder retainer screw and does nothing at the strike. For a strike fastener on a Corbin Russwin ML2000 mortise lock, the 206F57-8 strike combo screw is the part for that location. Confirm which lock line the door carries before ordering, since the 206F57-8 is an ML2000 part and the B520-298 serves Schlage B-Series and S200 cylinders.
6) Is this a residential or commercial-grade part?
Commercial. The B520-298 is specified for commercial door hardware and is used across offices, schools, healthcare, government buildings, retail, warehouses and multi-tenant residential openings, which is where the Schlage B600, B700, B800 and S200 cylinders it serves are typically installed.
7) Do I need to take the lock apart to replace the cylinder retainer screw?
The B520-298 is an installation accessory that goes in during cylinder installation or servicing, so it is reached the same way you reach the cylinder. Since it is the factory-spec #10-32 x 3/8 inch screw, there is no drilling or tapping involved. Swap it when you change a cylinder, or when the head is chewed up and the cylinder no longer sits tight.
8) When I am rebuilding a mortise lock and need both trim and cylinder fasteners, does one screw pack cover it?
No single pack covers both. The Schlage B520-298 covers only cylinder retention, as a #10-32 x 3/8 inch Phillips head screw with an anti-pry shield. On the Corbin Russwin ML2000 side, escutcheon trim fasteners come as separate packs by escutcheon style - the 429F31 for the N escutcheon and the 433F77 for M and P escutcheons. Plan on ordering the cylinder fastener and the trim fastener as separate line items for a full rebuild.
