Clamping Stud

Material to ASTM A 311 Class B
HIGH TENSILE STRENGTH

*Studs too short for given thread lengths are threaded as close to center as practical.

Table Clamping — The stud locks in the heavy part of the Northwestern T-Slot Nut. This prevents damage to the nut and also to the machine table.

Fixture Clamping — A Northwestern Heavy Nut is used to lock the stud in position at the exact length required.

**Conform to TCMAI/NIJFCM standards
