Dormakaba 54428-000-10 – Frequently Asked Questions

1) Can a Corbin Russwin ML2000 screw pack be used in place of the Dormakaba 54428-000-10 combination chamber screws?
No. The Dormakaba 54428-000-10 is a combination chamber screw kit for Dormakaba commercial mechanical lock assemblies, and its fasteners are matched to that combination chamber. The Corbin Russwin screw packs are built for the ML2000 mortise lock line - the 429F31 is a screw packet for the N escutcheon and the 433F77 covers the M and P escutcheons. Those secure trim to an ML2000 mortise case, not a combination chamber, so they are not interchangeable with the Dormakaba kit.
2) Is the 54428-000-10 screw pack meant for commercial locks or residential hardware?
Commercial. The 54428-000-10 is catalogued for commercial mechanical lock applications, and the typical uses are office buildings, schools, healthcare, retail, industrial and warehouse, multi-tenant residential common areas, and municipal buildings. If you're servicing a residential-grade Dormakaba product, confirm the screw part number against that lock's own parts breakdown before ordering.
3) Are these genuine Dormakaba screws or an aftermarket equivalent?
Genuine Dormakaba, sourced from the manufacturer, which is what keeps the fastener matched to the combination chamber it threads into. Aftermarket screws in the right diameter can still strip a chamber or bottom out at the wrong length, so on a keyless mechanical lock rebuild the OEM part is the safer call.
4) Will the Dormakaba 54428-000-10 work as a strike screw?
It is not intended for that. The 54428-000-10 is an installation accessory for fastening combination chamber assemblies on Dormakaba commercial mechanical locks. If you need strike fasteners on a Corbin Russwin ML2000 opening, the 206F57-8 is the strike combo screw for that line. Ordering the combination chamber kit for a strike prep will leave you with the wrong fastener for the frame.
5) What is the difference between buying a screw pack like the Dormakaba 54428-000-10 and buying individual screws?
The 54428-000-10 ships as a 10-pack screw kit, so one order covers multiple combination chamber installations or a run of service calls. The single-fastener alternative in the mortise world is an item like the Corbin Russwin 425F86-8, a flat screw in 8-32 x 3/8 inch for the ML2000, or the 206F57-8 strike combo screw - each of those is a discrete screw rather than a kit. Pick the kit when you are stocking a truck or standardizing maintenance, and the individual screw when you are replacing one specific fastener.
6) Why buy a 10-pack of lock screws instead of one or two?
Service work is the reason. Combination chamber screws are small, easy to lose in the field, and you rarely want a truck roll held up by one fastener. Ten per kit covers several installs or service calls and gives a maintenance shop a stocking item on the shelf for ongoing lock work across a portfolio of doors.
