Frequently Asked Questions

Check your model’s OEM parts diagram. If 100264 is listed for the assembly you’re servicing, this is the correct fastener. When in doubt, provide your model and serial to confirm.

It’s commonly found in the fluid-end/manifold area and related plates/retainers where a low-profile, even clamp is needed.

Ensure threads are clean, seat components squarely, then tighten evenly to the OEM torque spec for the assembly. Re-check fasteners after initial run-in.
