Gibraltar 9663154 Press Fit Rest Button 52100 Steel

Product Description

The GIBRALTAR 9663154 is a press fit rest button machined from 52100 steel with a black oxide finish. Rest buttons are precision workholding components used in jigs, fixtures, and machine tool setups to provide a stable, repeatable contact surface for locating and supporting workpieces. This button features an unground press fit design with an overall length of 0.906 inches, a head height of 7/16 inches, an outside diameter of 5/8 inches, and a pin diameter of 0.376 inches. The 52100 alloy steel construction provides high hardness and wear resistance suited to production machining environments.

This rest button is intended for use in precision fixture and jig assemblies in industrial machining, tool-and-die, and metalworking applications. The press fit installation style allows the button to be driven directly into a prepared bore without threading, simplifying fixture assembly. The black oxide finish provides light corrosion resistance during storage and service. Machinists and toolmakers install these components when building or refurbishing workholding fixtures for milling, drilling, or grinding operations.

Key Features

• 52100 alloy steel construction for high hardness and wear resistance
• Black oxide finish for light corrosion protection
• Unground press fit design installs directly into a prepared bore
• 0.906 inch overall length with 7/16 inch head height
• 0.376 inch pin diameter for consistent bore fitment
• 5/8 inch outside diameter head provides stable workpiece contact surface

Compatibility

Designed as a standard press fit rest button for use in precision jigs, fixtures, and workholding assemblies requiring a 5/8 inch OD seating diameter and a 0.376 inch press fit pin.

Installation Notes

Installation is performed by machinists or toolmakers using a press or suitable driving tool to seat the pin into a precisely reamed bore. Ensure the receiving bore is dimensioned to the correct interference fit tolerance before pressing. Do not hammer the button directly on the head face, as this may damage the seating surface. Verify button seating depth and flush condition before placing the fixture into service.
