Adams Rite S262-10R28-603 – Frequently Asked Questions

1) What Adams Rite cylinder pulls does the S262-10R28-603 screw fit?
The S262-10R28-603 is the Adams Rite replacement fastener for the 4025 and 4026 cylinder pull series. It is an OEM part sold for those assemblies, so it is not a general-purpose fastener for other Adams Rite trim.
2) What thread size and length is the Adams Rite S262 cylinder pull screw?
It is a #10-32 x 1-3/4 inch flat head machine screw. The #10-32 is a machine thread, so it threads into the tapped hole in the pull assembly rather than cutting its own thread, and the 1-3/4 inch length is what reaches through the door prep on the 4025/4026 pull.
3) Can a Corbin Russwin ML2000 screw pack be used in place of the Adams Rite S262-10R28-603 cylinder pull screw?
No. The Adams Rite S262-10R28-603 is a #10-32 x 1-3/4 inch flat head screw made specifically for the Adams Rite 4025 and 4026 cylinder pull series, and the thread and length are matched to that assembly. The Corbin Russwin 429F31 screw packet is built for the ML2000 N escutcheon, and the 433F77 packet is for the ML2000 M and P escutcheons, so both are sized for a mortise lock trim rather than a cylinder pull. Order the S262-10R28-603 when the fastener is coming out of a 4025 or 4026 pull.
4) Why a flat head screw on a cylinder pull instead of a pan head?
Flat head is what the 4025/4026 pull is countersunk for. The head seats flush with the pull face so nothing catches a hand or a passing cart, and a pan or round head would stand proud and can interfere with the cylinder or trim sitting down properly.
5) Can I just replace the screws instead of the whole cylinder pull?
That is what this part exists for. It replaces worn, damaged, or missing fasteners in an existing cylinder pull installation, so a stripped screw does not force you to buy a new pull. For a property manager keeping storefront doors in service, stocking a few is cheaper than swapping trim.
6) What is the difference between the Adams Rite S262-10R28-603 screw and the Corbin Russwin 425F86-8 flat screw?
Both are flat head machine screws for commercial door hardware, but the threads and lengths are different and so are the assemblies they serve. The Adams Rite S262-10R28-603 is #10-32 x 1-3/4 inch, zinc plated, for the 4025 and 4026 cylinder pulls. The Corbin Russwin 425F86-8 is an 8-32 x 3/8 inch flat screw for the ML2000 mortise lock line. They are not interchangeable in either direction.
7) I need a strike screw, not a cylinder pull screw. What should I order instead of the Adams Rite S262-10R28-603?
The S262-10R28-603 is a cylinder pull fastener for the Adams Rite 4025 and 4026 series and will not serve as a strike fastener. For strike work on a Corbin Russwin ML2000 mortise lock, the 206F57-8 is a Grade 1 strike combo screw made for that application. Match the fastener to the component being reattached rather than to head style alone.
8) Is a zinc plated 603 finish screw okay on an exterior storefront door?
The zinc plating (603) is there for corrosion resistance in commercial service, and these screws sit behind or flush in the pull where they are largely shielded. On a heavy salt-air or wash-down opening, plated steel is still plated steel, so expect normal maintenance rather than stainless-grade performance.
9) For a maintenance kit, should I stock the Adams Rite S262-10R28-603 as a single screw or a multi-piece pack like the Corbin Russwin 433F77?
It depends on what you are servicing. The Adams Rite S262-10R28-603 is supplied as a screw pack item for the 4025 and 4026 cylinder pulls in a zinc plated 603 finish, so it covers pull fastener replacement on storefront and commercial openings. The Corbin Russwin 433F77 is a screw pack for ML2000 M and P escutcheons, and the 429F31 covers the N escutcheon, so those belong in a kit built around mortise lock trim. Facilities running both hardware types typically stock one of each rather than substituting.
10) Is this a commercial-duty part or a residential hardware screw?
Commercial. It is catalogued and built for commercial door hardware service, which is where the Adams Rite 4025/4026 cylinder pulls live, typically aluminum storefront and mixed-use entrances.
