Gibraltar 64255730 Press Fit Rest Button Hardened Steel

Product Description

The GIBRALTAR 64255730 is a press fit rest button designed for precision workholding and fixturing applications. Machined from hardened steel with a ground finish and black oxide coating, this rest button provides a stable, wear-resistant contact point in jigs, fixtures, and machine tool setups. It measures 5/8 inch overall length with a 3/8 inch outside diameter and a 1/4 inch head height. The ground press fit interface ensures accurate, repeatable seating without the need for adhesives or fasteners. At 0.05 pounds, it is a compact, durable component suited for high-cycle production environments where consistent part location is critical.

This rest button is used in toolroom, production machining, and fixture-building applications where a hardened, ground contact surface is required to locate and support workpieces. The press fit design allows installation directly into a bored hole in a fixture plate or tombstone, eliminating movement during clamping. The black oxide finish provides mild corrosion resistance in shop environments. Toolmakers, fixture builders, and machining professionals typically specify this style of rest button for high-precision, repetitive part-locating setups in both manual and CNC machining cells.

Key Features

• Hardened steel construction for wear resistance in high-cycle fixturing applications
• Ground press fit body ensures accurate, repeatable seating in bored holes
• Black oxide finish provides mild corrosion resistance in shop environments
• 5/8 inch overall length with 1/4 inch head height for low-profile workpiece contact
• 3/16 inch pin diameter with 3/8 inch pin length for secure press fit retention
• Compact 0.05 pound weight suits high-density fixture layouts

Compatibility

Designed as a standard press fit rest button for use in fixture plates, jig bodies, and tooling blocks bored to accept a 3/8 inch outside diameter press fit component.

Installation Notes

Installation is performed by toolmakers or fixture builders using a press or arbor press to seat the button into a precision-bored hole. The receiving bore should be sized to the manufacturer's press fit tolerance to ensure proper retention and prevent rotation or pullout during use. Do not drive the button in with a hammer, as this can damage the ground surfaces. Inspect the seating depth and head contact surface for flush fit before placing the fixture into service.
