Schlage B520-693 – Frequently Asked Questions
1) Will the B520-693 screw fit a Schlage lock other than the L Series?
Schlage lists the B520-693 for the L Series modular mortise housing only. If you're working on a Schlage cylindrical lock such as the ND or AL Series, or on a B Series deadbolt, this is not the fastener for it - match the screw to that specific line instead.
2) Does the finish code on a Schlage L Series replacement screw matter?
It can. Many Schlage parts are finish specific, so the 693 suffix on B520-693 identifies the finish variant of this screw. If the screw sits anywhere visible on the trim, order the finish that matches the rest of the hardware on the door rather than assuming any B520 will do.
3) Is this a commercial-grade screw or a residential one?
The B520-693 is a commercial part, supplied for Schlage's L Series mortise locks used in offices, schools, healthcare and multi-family buildings. It is not intended as a general residential fastener.
