Schlage N123-020 613 – Frequently Asked Questions

1) What exactly comes in the Schlage N123-020 screw pack?
Each N123-020 pack contains four C603-897 screws, two C603-256 screws, two N523-021 components, and one M504-271 component. That is the full mounting hardware set for an ND Series lock installation in one bag, so you are not chasing loose fasteners on site.
2) What is the Corbin Russwin equivalent of the Schlage N123-020 screw pack?
There is no cross-brand equivalent in the true sense, because mounting screw packs are keyed to the lock chassis they fasten. The Schlage N123-020 is a screw pack for ND Series locks, excluding the ND170, containing four C603-897 screws, two C603-256 screws, two N523-021 components and one M504-271 component. On the Corbin Russwin side, the comparable item for a mortise lock is the 429F31 Grade 1 screw packet for the N escutcheon or the 433F77 Grade 1 screw pack for M and P escutcheons, both for the ML2000 mortise line. Order by the lock family on the door: ND Series takes the N123-020, ML2000 escutcheons take the Corbin Russwin packs.
3) My lock is an ND170 - will the N123-020 pack work?
No. The Schlage N123-020 mounting screw pack covers the ND Series lockset range with the ND170 specifically excluded, so it is not the correct fastener set for that model. It is also not a substitute for mortise lock hardware - the Corbin Russwin 429F31 and 433F77 screw packs serve the ML2000 mortise escutcheons, which is a different mounting entirely.
4) I manage a building with Schlage ND locks. Are these the right screws for a lever or rose replacement?
Yes, for ND Series cylindrical locks other than the ND170. The N123-020 is the genuine Schlage installation accessory pack built to original factory specification, so the screw sizes and lengths match the ND chassis and trim you are reinstalling. It is a commercial-grade part intended for commercial door hardware work.
5) I only stripped one screw - do I need a whole pack or can I buy a single screw?
The Schlage N123-020 is sold as a complete pack of all required fasteners for an ND Series mounting, not as loose pieces. If a single fastener is all you need and the door carries a Corbin Russwin ML2000 mortise lock rather than a Schlage ND, individual screws are catalogued for that line: the 425F86-8 is a flat screw in 8-32 x 3/8 inch, and the 206F57-8 is a strike combo screw. For an ND Series lock, the pack is the way the components are supplied.
6) I am standardizing a building on one lock line - how do the screw packs differ between cylindrical and mortise hardware?
They are separate kits tied to separate chassis types. The Schlage N123-020 is a commercial installation accessory for ND Series locks and comes in a 613 Oil Rubbed Bronze finish so it coordinates with matching ND trim. Corbin Russwin's mortise equivalents split by escutcheon shape: the 429F31 Grade 1 packet for the N escutcheon and the 433F77 Grade 1 pack for M and P escutcheons. If you standardize on ND Series, one screw pack part number covers the range; if you standardize on ML2000 mortise, the pack you stock depends on which escutcheon your trim uses.
7) Is the N123-020 a single loose screw or a full kit?
It is a full kit, not an individual fastener. Nine pieces across four part numbers ship together. If you only need one replacement screw, single-piece items exist in this category, for example the Corbin Russwin 425F86-8 flat screw in 8-32 x 3/8 inch for ML2000 locks, but that is a Corbin part and will not serve a Schlage ND lock.
8) Should I stock the N123-020 for a facility standardized on Schlage ND locks?
It makes sense if your ND openings are finished in oil rubbed bronze. Schools, hospitals, offices, government buildings, retail, multi-tenant residential and warehouse facilities all run ND Series hardware, and having the factory mounting pack on the shelf keeps a lock service call from turning into a second trip. Just keep the ND170 exception in mind when you build the stock list.
9) Can I use a strike screw in place of a lock mounting screw?
No - they do different jobs. The Schlage N123-020 supplies through-bolt and mounting hardware for assembling an ND Series lock on the door. A strike screw such as the Corbin Russwin 206F57-8, which is a strike combo screw, fastens the strike into the frame, and a flat screw like the 425F86-8 at 8-32 x 3/8 inch is a short fastener for a specific ML2000 point. Substituting one for another risks wrong length and wrong thread for the chassis.
