Common questions

What does open end mean?
The end of the nut is open instead of capped, so the stud can pass through the nut. That makes them a practical choice when your studs sit longer than a closed-end nut would cover, and it lets you see full thread engagement at a glance.

Do these need a special socket?
They install with the included spline key rather than a standard socket on the nut itself. Your 3/4" or 13/16" socket or wrench drives the key, and extra keys are available from the accessories on this page.
