Dormakaba 44121-000-10 – Frequently Asked Questions

1) What does a shoulder screw do differently from a standard machine screw in a lock assembly?
A shoulder screw has an unthreaded shank section that sets a fixed seating depth, so the part it holds is positioned precisely rather than clamped down by however far you drive it. On the Dormakaba lock-in slide, that controlled depth is what keeps the slide located correctly, which is why a generic machine screw is not a substitute.
2) Can a Corbin Russwin ML2000 screw pack be used in place of the Dormakaba 44121 shoulder screws?
No. The Dormakaba 44121-000-10 is a 10-pack of Lock-In Slide shoulder screws purpose-made for Dormakaba mechanical lock assemblies, where the shoulder controls the fastening depth and positioning of the Lock-In Slide component. The Corbin Russwin 433F77 is a screw pack for ML2000 M and P escutcheons, and the 429F31 is a screw packet for the ML2000 N escutcheon - both are escutcheon mounting hardware for a different manufacturer's mortise lock. They are not dimensional equivalents to a shoulder screw and should not be substituted into a Dormakaba lock-in slide.
3) How many screws come in the Dormakaba 44121 lock-in slide shoulder screw pack?
Ten shoulder screws per pack. The 44121-000-10 is sold as a 10-pack, which is enough for several installations or to keep as shelf stock for a maintenance crew servicing Dormakaba mechanical lock hardware.
4) What is the difference between a shoulder screw pack and a flat screw for mortise lock work?
A shoulder screw, like the Dormakaba 44121 Lock-In Slide screw, has an unthreaded shoulder below the head that sets a fixed seating depth so a moving or located component sits in the same position every time. A flat screw such as the Corbin Russwin 425F86-8, an 8-32 x 3/8 inch flat screw for ML2000 locks, is a plain threaded fastener that pulls a part tight against its mating surface. If the assembly relies on a controlled standoff, a flat screw will not reproduce it.
5) I am restocking commercial mortise lock fasteners for a maintenance cart - how do these screw options differ by brand?
Keep them separated by lock platform. The Dormakaba 44121-000-10 supplies ten Lock-In Slide shoulder screws for Dormakaba commercial mechanical lock assemblies. On the Corbin Russwin ML2000 side, the 206F57-8 is a strike combo screw, the 425F86-8 is an 8-32 x 3/8 inch flat screw, and the 429F31 and 433F77 are escutcheon screw packs for N and for M and P trim respectively. Each addresses a different point on the lock, so stocking one does not cover the others.
6) My strike is loose on a mortise lock - is the Dormakaba 44121 the screw for that?
No. The 44121-000-10 shoulder screws are installation hardware for Dormakaba Lock-In Slide components inside the lock assembly, not strike fasteners. For a loose strike on a Corbin Russwin ML2000, the strike combo screw is the 206F57-8. Match the screw to the specific lock brand and to the point on the opening being fastened.
7) Is the Dormakaba 44121 screw pack suitable for commercial door hardware, or is it a residential part?
It is a commercial part. Dormakaba lists the 44121 as commercial-grade, and it is used in offices, schools, healthcare, retail, industrial buildings, multi-tenant residential and government facilities where the mechanical lock hardware sees constant traffic.
8) Are these genuine Dormakaba parts or an aftermarket equivalent?
Genuine Dormakaba. The 44121-000-10 is an authentic factory installation accessory, made to the same specification as the lock hardware it mounts, so the fit and thread match the original components rather than approximating them.
9) Is there more than one version of the Dormakaba 44121 screw pack to choose from?
No options to specify. The 44121 lock-in slide shoulder screws ship in a single configuration, the 10-pack under model 44121-000-10, so ordering is just a matter of how many packs you need.
