Gibraltar 9663212 Press Fit Rest Button 52100 Steel

Product Description

The GIBRALTAR 9663212 is a press fit rest button designed for use in workholding, fixturing, and precision machining setups. It features a hardened 52100 steel body with a black oxide finish for corrosion resistance. The button measures 1-3/32 inches overall length with a 7/8 inch outside diameter and a 1/2 inch head height. The unground press fit design allows for fast installation into a prepared bore without secondary grinding operations. A pin diameter of 0.501 inches ensures consistent, repeatable seating. Machinists, toolmakers, and fixture builders working in production or job shop environments typically source and install this component.

Rest buttons like the GIBRALTAR 9663212 are used in jigs and fixtures to provide a precise, wear-resistant contact point for locating and supporting workpieces during machining operations. The hardened 52100 steel construction stands up to repeated part contact and clamping forces. This style is suited for applications where the button is pressed into a drilled and reamed hole in a fixture plate, tooling block, or jig body. It is a standard component in the toolmaking trade and is compatible with conventional press fit installation procedures.

Key Features

• Unground press fit design for direct installation into a prepared bore
• 52100 hardened steel construction for durability under repeated contact loads
• Black oxide finish provides corrosion resistance and low-reflectance surface
• 1/2 inch head height provides a stable, flat locating surface for workpieces
• 7/8 inch outside diameter with 0.501 inch pin diameter for consistent fitment
• Single-piece solid construction with no moving parts

Compatibility

Designed as an OEM-style replacement and standard tooling component for use in precision jigs, fixtures, and workholding setups requiring press fit rest buttons with a 7/8 inch outside diameter and 0.501 inch press fit pin.

Installation Notes

Installation is performed by toolmakers or machinists using a press or arbor press to seat the button into a reamed bore. The receiving hole should be prepared to the appropriate press fit tolerance for the 0.501 inch pin diameter before installation. Avoid driving the button in with impact tools, as this can damage the seating bore or distort the button head. Ensure the fixture plate or jig body is secured and the button is aligned square before applying press force.
