Gibraltar 85548691 Clamp Rest Support 3/8-16 Thread

Product Description

The GIBRALTAR 85548691 is a lead alloy clamp rest support designed for use in industrial clamping and fixturing applications. Constructed from steel with a black oxide coating, this support features a 3/8-16 thread and measures 2.5 inches in overall length with a thread length of 1.8125 inches. The pin measures 0.34375 inches in diameter and 0.15625 inches in height. The black oxide finish provides corrosion resistance and reduces light reflection, making it a practical choice for machine shop and assembly environments. Typically installed by machinists, tool and die technicians, and mechanical assembly professionals.

This clamp rest support is suited for use in workholding setups where a stable, threaded rest point is required. The 3/8-16 thread size is a common standard thread pitch widely compatible with modular fixturing systems and clamping hardware. The 0.5625-inch size designation and compact 2.5-inch length make it appropriate for applications where space is limited and precise part positioning is required. Sold individually.

Compatibility

Designed as an OEM-style replacement or supplemental component for standard 3/8-16 threaded workholding, clamping, and fixturing systems commonly used in industrial machine shop environments.

Installation Notes

Installation is typically performed by machinists or mechanical technicians using standard hand tools compatible with the 3/8-16 thread standard. Ensure the mating threaded bore is clean and free of debris before threading in the support. Do not overtighten, as the lead alloy rest element may be damaged by excessive clamping force. Verify workpiece contact point alignment before securing the support in its final position.
