JG Micro OK Vise Clamps: Precision Workholding Solutions


Compact, High-Precision Clamping for Specialized Manufacturing Applications

Freer Tool & Supply distributes professional Jergens Micro™ clamp kits engineered for compact, high-precision clamping in specialized manufacturing applications. As your authorized Jergens distributor in Michigan, we provide the complete range of micro clamp kits including knife edge and blunt edge configurations in steel, brass, and tool steel construction with thread sizes from 4-40 to 1/2-13 imperial and M2.5 to M12 metric.


Micro™ Clamps 

Jergens Micro™ Clamps feature both high hold-down forces and low profiles, which make them ideal for building fixtures on Ball Lock® fixturing plates. Two simple components make them work: a hardened steel socket cap screw with an offset head and a hexagonal washer. A half-turn tightens or loosens the workpiece.
