Corbin Russwin 429F31-626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 429F31 screw pack, and what does it fasten?
The 429F31 is the genuine Corbin Russwin fastener packet for mounting an N escutcheon trim to an ML2000 Series mortise lockset. It's the screws only, not the escutcheon plate and not the lock body. If you're replacing damaged or missing mounting hardware on an existing ML2000 with N trim, this is the part. If you need the trim itself or the lockbody, order those separately.
2) Will the 429F31 screw pack work with sectional trim on an ML2000 mortise lock?
No. This pack is cut for the N escutcheon trim on the ML2000. Sectional trim mounts differently and takes its own fastener set. Look at the trim already on the door: if it's a full escutcheon plate in the N design, this is the right pack. If it's a separate rose and lever, you need the sectional hardware instead.
3) Why do I have to pick 6-pin or 7-pin when ordering an escutcheon screw pack?
The N escutcheon carries the cylinder, and the cylinder length changes with pin count, so the fastener pack is matched to it. The 429F31 comes in both a 6-pin and a 7-pin version. ML2000 locks ship standard with a 6-pin brass cylinder in the L4 keyway, so 6-pin is the common pick; order the 7-pin version if your building is keyed on a 7-pin large format system such as an interchangeable core.
4) My door is thicker than 1-3/4 inches. Will the standard 429F31 screws be long enough?
The ML2000 is built around a 1-3/4 inch (44mm) door as standard, with optional thicknesses offered, and the stock screw pack is sized to that standard. On anything thicker the thru-bolt length is the thing that changes, so confirm your door thickness before ordering. Measure the leaf, not the frame.
5) What finishes does the Corbin Russwin 429F31 screw pack come in, and does it need to match my trim?
Four: 605 bright brass, 612 satin bronze, 613 oil-rubbed satin bronze, and 626 satin chrome. Exposed escutcheon screw heads show on the door face, so match the pack to the finish of the trim you're fastening. On a multi-building portfolio standardized on 626, that's the one to stock.
6) Is the 429F31 a thru-bolt pack or does it just screw into the lock case?
ML2000 escutcheon trim is thru-bolted, which is how Corbin Russwin keeps the two trim plates aligned and pulls the assembly tight through the door for security. The N escutcheon pack supplies those fasteners. That also means both faces of the door come off together during service, so plan on working from both sides of the opening.
7) Can I use the 429F31 screw pack on a fire rated door without voiding the label?
Using genuine Corbin Russwin fasteners is what keeps the assembly as listed. The ML2000 is UL/cUL listed to UL10C positive pressure and carries a 3-hour rating on single doors up to 4 by 10 feet and pairs up to 8 by 10 feet. Substituting hardware store screws on a labeled opening is where inspectors write it up, so stay with the OEM pack.
8) Does the escutcheon screw pack change anything about handing when I rehand an ML2000?
No. The ML2000 uses a quick reversible latchbolt, so the lock is rehanded without opening the case, and the escutcheon fasteners are the same either way. What does change is the orientation of the trim plate itself and the cylinder and thumbturn positions, which sit at 3-5/8 inches center to center lever to cylinder and 2-7/16 inches lever to thumbturn.
9) I'm doing a service call on an ML2000. What else should I have on the truck besides the screw pack?
Depends on what failed. The screw pack only covers the N escutcheon fasteners. The lock itself runs a 2-3/4 inch backset with a 3/4 inch (19mm) anti-friction latchbolt, a 9/16 inch effective auxiliary latch, and a 1 inch throw stainless deadbolt into an ANSI straight lip strike, 4-7/8 by 1-1/4 with 1-1/8 lip to center. If the deadbolt isn't seating, that's a strike or frame issue, not a fastener issue.
10) Is this screw pack rated for commercial traffic or is it a residential part?
Strictly commercial. It supports the ML2000, which is ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1 and tested to 14.5 million cycles. That's the level used in schools, hospitals, offices and multi-tenant residential corridors.
