Gibraltar 53005G Plunger Wrench 5/16-18 M8

Product Description

The GIBRALTAR 53005G is a plunger wrench designed for installing and removing threaded plungers in industrial and mechanical assemblies. Sized for 5/16-18 and M8 thread standards, this wrench provides a secure fit on the hex drive feature found on spring plungers, ball plungers, and stubby plungers. The compact form factor allows access in tight clearances where a standard wrench cannot reach. Maintenance technicians and machine builders use this tool when setting or replacing plungers in fixtures, jigs, and positioning assemblies.

This wrench is suited for light industrial applications including fixture building, machine tool maintenance, and production line servicing. It is sized specifically for 5/16-18 unified coarse thread and M8 metric thread plungers, making it useful in shops that run both inch and metric hardware. The tool is relevant wherever spring, ball, or stubby plungers are installed into tapped holes that require controlled engagement force.

Key Features

• Fits both 5/16-18 inch and M8 metric threaded plungers in a single tool
• Compatible with spring plungers, ball plungers, and stubby plungers
• Compact design for access in confined fixture and machine tool locations
• Sold individually, no multi-pack required

Compatibility

Designed for use with spring, ball, and stubby plungers threaded to 5/16-18 inch or M8 metric specifications.

Installation Notes

Use this wrench to drive or extract plungers by hand in tapped holes. Ensure the mating tapped hole is clean and free of debris before installation. Do not apply excessive torque beyond the plunger manufacturer's specified seating load, as this can damage the plunger body or the receiving thread. No power tools are required for this operation.
