Carr Lock® Fixture Machining Kits

Carr Lock System

Product Information

Carr Lock® Fixture Machining Kits are extremely useful for machining a fixture using the Carr Lock® mounting holes as an absolute reference. The kit consists of four extra-long Carr Lock® Clamps, used together with four precision-height spacers, providing ample clearance underneath the fixture plate to allow through-hole machining without damaging the subplate. The kit also includes an extra four spacers to use as additional supports under large plates, all in a handy carrying case. Made in USA.

Available in 20mm and 25mm shank diameter for the following plate thicknesses:

20mm dia (3/4" plate thickness)

25mm dia (3/4" plate thickness)

25mm dia (1" plate thickness)

Application Information

Design Considerations & Safety Precautions

Carr Lock® Clamps should only be used to locate and clamp flat plates on machine tools. Each top plate should have one Carr Lock® mount designated as its primary reference point, and one as its secondary reference point. These two mounts should be as far apart as possible. The secondary reference point should have a relieved liner to avoid redundant location (binding). Additional Carr Lock® Clamps can be used for more clamping force, but these should be installed in clearance holes, not locating liners. Note that the same Carr Lock® Clamp fits into any type of liner or a clearance hole. Carr Lock® Clamps must be used with Carr Lock® Receiver Bushings for proper operation. Plate thickness must be +/-.005" to achieve full clamping force. Do not exceed maximum screw torque shown.
