Gibraltar 85548709 Clamp Rest Support 1/2-13 Thread

Product Description

The GIBRALTAR 85548709 is a clamp rest support designed for secure clamping and workholding applications in industrial and trade settings. Constructed from steel with a black oxide coating, this support features a 1/2-13 thread and measures 2.375 inches in overall length with a 1.5-inch thread length. The pin diameter is 0.34375 inches with a pin height of 0.1875 inches, and the nut height is 0.5 inches. The black oxide finish provides corrosion resistance and reduces surface glare. At 1.88 pounds, this is a solid, durable component suited for machining, fabrication, and fixture work.

This clamp rest support is used in workholding fixtures, jigs, and clamping setups common in machine shops, fabrication facilities, and industrial maintenance environments. The 1/2-13 thread size makes it compatible with standard clamping hardware and fixture plates. It is typically installed by machinists, toolmakers, and industrial maintenance technicians working with clamping systems that require a stable rest point for workpieces or tooling assemblies. The 7/8-inch size designation refers to the body size of the support.

Installation Notes

Installation is performed by machinists or industrial maintenance technicians. Ensure the mating fixture plate or clamping body is clean and free of debris before threading in the support. Use appropriate torque to seat the nut without stripping the 1/2-13 thread. Inspect the pin and nut height clearances against the workpiece before final clamping to confirm proper support positioning.
