Schlage K510-390 626 – Frequently Asked Questions

1) Will the Schlage K510-390 screw work with any Schlage L Series trim?
It is made for the L Series N escutcheon trim specifically. Other L Series trim styles (rose trim, other escutcheon designs) use their own thru-bolt parts, so confirm your lock is built with the N escutcheon before ordering this one.
2) I'm replacing a stripped mounting screw on an L Series mortise lock. Is this the right part?
If the lock uses the N escutcheon trim and the door is 2 to 2-1/4 inches thick, yes. The K510-390 is the genuine Schlage thru-bolt that pulls the escutcheons together through the door, and it drops straight into the existing prep with no modification.
3) What finishes does the Schlage K510-390 thru-bolt screw come in?
Six finishes, so the screw head matches the trim: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome and 626 satin chrome. Order the same finish code as the escutcheon it is going through, since the head is visible on an exposed thru-bolt.
4) Can I substitute a hardware-store machine screw for the Schlage K510-390?
Not reliably. Thru-bolt length is matched to the door thickness so the escutcheons pull tight without bottoming out or leaving the trim loose, and the head finish is matched to the Schlage finish codes. A generic screw in the wrong length lets the trim shift and puts the lockset out of alignment.
5) Is the Schlage K510-390 a residential or commercial part?
Commercial. It supports the L Series mortise lock line used in offices, schools, healthcare, government buildings, retail, warehouses and multi-tenant housing, and it is a genuine Schlage installation accessory rather than a generic fastener.
6) Does buying the K510-390 get me a full set of screws or a single screw?
The K510-390 is Schlage's thru-bolt screw part for the L Series N escutcheon. Count how many fasteners your trim uses per side and order quantity to match, since escutcheon trim is normally thru-bolted at more than one point.
