Von Duprin 963581 – Frequently Asked Questions

1) What Von Duprin exit devices does the 963581 socket set screw fit?
The 963581 socket set screw is a genuine Von Duprin replacement fastener for the 550, 555 and 556 Series exit devices. It is made to the original factory dimensions for those devices, so it drops into the same threaded location the original screw came out of. It is not a general-purpose set screw for other Von Duprin families such as the 98/99 or 33A/35A rim and vertical rod devices.
2) What exactly is the Von Duprin 963581, a whole exit device or just a fastener?
Just the fastener. The 963581 is a single socket set screw, a service part sold to repair an existing 550, 555 or 556 Series exit device. If your device itself is damaged or missing components, you need the device or the relevant assembly, not this screw.
3) Is the Von Duprin 963581 an OEM part or an aftermarket screw?
OEM. The 963581 is an authentic Von Duprin component catalogued as a replacement part, not a generic hardware-store set screw. For a locksmith or facility maintenance tech servicing a 550, 555 or 556 device, that matters because the thread and length are held to the device's original tolerances rather than a close approximation.
4) Is this set screw suitable for a high-traffic commercial opening, or is it a light-duty part?
Heavy duty, and rated for commercial use. That is the duty class Von Duprin assigns the 963581, which is what you want on school, healthcare and office egress doors where the device cycles constantly and a backed-out fastener means a loose component on a fire exit.
5) How do I order the right Von Duprin exit device screw without a part diagram?
Order by the Von Duprin part number stamped in the parts list for your device series. For the 550, 555 and 556 Series, the socket set screw is number 963581, and that number is the only thing you need to specify. There are no finish, length or handing options on it, so one line item covers it.
