Gibraltar 64255755 Press Fit Rest Button Hardened Steel

Product Description

The GIBRALTAR 64255755 is a press fit rest button designed for use in precision workholding, fixturing, and tooling applications. Machined from hardened steel with a ground finish, this rest button provides a stable, repeatable contact surface for locating and supporting workpieces during machining operations. The button measures 7/8 inch overall length with a 3/8 inch head height and 1/2 inch outside diameter. A 1/4 inch diameter pin (0.2510 inch decimal) extends 1/2 inch for secure press fit installation into tooling plates and fixture bodies. Black oxide coating adds corrosion resistance. Machinists, toolmakers, and fixture builders install this type of component in production and job shop environments.

This rest button is suited for use in machine shop fixtures, jigs, and modular workholding systems where precise part location is required. The ground contact face ensures consistent seating height across multiple buttons in a fixture setup, supporting tight tolerance work on milling machines, machining centers, and similar equipment. The press fit pin retains the button securely in the fixture plate without additional fasteners.

Key Features

• Press fit installation via 0.2510 inch diameter ground pin for secure retention in fixture plates
• Ground contact face ensures repeatable seating height and precise part location
• Hardened steel construction for wear resistance in production tooling environments
• Black oxide coating provides corrosion resistance
• Compact 7/8 inch OAL with 1/2 inch OD head suits tight fixture layouts

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard press fit rest button applications in machining fixtures, jigs, and tooling plates accepting a 1/4 inch press fit pin.

Installation Notes

Installation is performed by toolmakers or machinists using a press or arbor press to drive the button pin into a precisely bored hole in the fixture plate. Power down all machine tools before installing or removing rest buttons from active fixtures. Ensure the receiving hole diameter matches the 0.2510 inch pin diameter for proper press fit retention. Consult fixture design standards and shop tolerancing practices for hole depth and surface finish requirements.
