Schlage B520-691 – Frequently Asked Questions
1) I'm restocking my locksmith van for Schlage L Series work. Should I keep cam screws on hand?
Yes. The B520-691 cam screw is the piece most often lost or stripped during a cylinder swap on an L Series mortise lock, and it is not an item most supply houses carry loose. Keeping a few in the van means a stripped screw does not turn a rekey into a return trip. Note that Schlage lock parts are frequently finish specific, so check that against any visible trim pieces you also stock.
2) Is this Schlage cam screw a commercial-grade part or for residential locks?
It is a commercial part. The Schlage L Series mortise lock line it serves is commercial mortise hardware, typical of schools, offices, healthcare and multi-family corridor doors rather than residential bored locks.
