Jergens®, 39520, Sine Fixture Key, Multi-Slot, Shank Diameter Compatibility: 0.625 in, 1-3/16 in Overall Height

Jergens Sine Fixture Keys locate jigs and fixtures on machine tool tables and position the part to be machined in one operation. They eliminate the need to slot fixture bases, make step fixture keys, or drill and tap keys. All you need to do is ream two 5/8" or 3/4" holes, depending upon the table size. The wide range of Sine Fixture Key sizes adapts to the various table slot widths. The tapered expansion screw allows the key to be locked in the fixture from either the top or the bottom by using a standard 3/32" or 4mm hex wrench.Features, Benefits, & Product Specifications:Material: AISI 4140 Alloy SteelHeat Treat: Through Hardened to RC 26-30One key fits multiple table slotsReduce fixture costsCut set-up timeInterchangeable with other Sine Fixture KeysThe replacement screw for all Sine Fixture Keys is Part No. 710190
