Gibraltar 85548717 Clamp Rest Support 7/8 in Steel

Product Description

The GIBRALTAR 85548717 is a clamp rest support designed for use in mechanical fastening and workholding applications. Machined from steel with a lead alloy composition, this support features a 5/8-11 thread and measures 3-27/32 inches in overall length. The black oxide finish provides a base level of corrosion resistance for shop and industrial environments. It is sized at 7/8 inches and includes an integrated pin for positive part location. Licensed trade professionals and skilled machinists install this type of component in jigs, fixtures, and clamping assemblies where repeatable part positioning is required.

This clamp rest support is suited for use in machine shop tooling, fixture building, and industrial workholding setups. The 5/8-11 thread allows it to be threaded directly into standard fixture plates or modular tooling blocks. The pin geometry, with an 11/32-inch diameter and 3/16-inch height, engages locating features to prevent part movement during clamping operations. It is appropriate for light to medium-duty clamping applications in both production and job-shop settings.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Thread the support into the fixture plate by hand first, then torque to the fixture designer's specification using an appropriate wrench on the nut. Ensure the locating pin is properly aligned with the workpiece before applying clamping force. Inspect threads for damage before installation and do not use if thread integrity is compromised.
