Falcon SCREW.1143 – Frequently Asked Questions

1) What size is the Falcon SCREW.1143 replacement screw?
The Falcon SCREW.1143 is an 8-18 x 1-1/4 inch screw with a flat Phillips head and a Type 25 thread form. The 8-18 designation is the #8 diameter with 18 threads per inch, and 1-1/4 inches is the length under the head. Flat head means it seats flush into a countersunk hole, so it will not stand proud of an exit device chassis or cover.
2) Will the SCREW.1143 work on my Falcon exit device?
It is a Falcon OEM part made for Falcon exit device assemblies, sold under Falcon part number SCREW.1143. If the screw you are replacing is called out as SCREW.1143 in the Falcon parts breakdown for your device, this is the correct fastener. Because it is sized and threaded to one specific spec (8-18 x 1-1/4 inch, Type 25), match it against the screw you pulled out rather than assuming every screw in the device is the same one.
3) How many screws come in a pack of Falcon SCREW.1143?
Ten screws per pack. That quantity suits a maintenance crib or a service van where you want spares on hand rather than ordering one screw per call, and it covers multiple devices across a building.
4) What is a Type 25 thread screw, and can I substitute a standard machine screw?
Type 25 is a thread-cutting form: the screw cuts its own mating thread as it drives, which is why Falcon specifies it for exit device components rather than a plain machine screw. Substituting a standard 8-32 machine screw is not a like-for-like swap, since the thread pitch and the cutting geometry differ. Order the SCREW.1143 to match what Falcon called out.
5) What kind of screwdriver do I need for the SCREW.1143?
A Phillips driver. The SCREW.1143 uses a flat Phillips head (FPH), so it goes in and out with standard service tools, no specialty bit and no security head. If your existing exit device screws take a Torx or a spanner bit, you are looking at a different Falcon part.
6) Is this screw meant for commercial exit hardware or residential door hardware?
Commercial. The SCREW.1143 is catalogued as a commercial door hardware fastener for Falcon exit devices, the kind of hardware found in offices, schools, hospitals, retail, warehouses, government buildings, and multi-tenant residential properties. It is not a general-purpose wood screw.
