Gibraltar 9663071 Press Fit Rest Button 3/8in Od 52100 Steel

Product Description

The GIBRALTAR 9663071 is a press fit rest button designed for use in precision fixturing, jig building, and workholding applications. It features a 3/8 inch outside diameter and a 15/32 inch overall length, with a 1/4 inch head height and a 0.1885 inch pin diameter for secure press fit installation. Manufactured from 52100 steel and finished with a black oxide coating, this rest button delivers hardness and corrosion resistance suited to demanding shop environments. Machinists, toolmakers, and fixture builders typically install this component when establishing repeatable part-locating datums on jigs and fixtures.

This rest button is appropriate for use in machine shop and manufacturing environments where consistent part seating and location are required. The unground press fit style suits applications where the button is pressed directly into a drilled hole in a fixture plate or jig body, providing a stable, repeatable contact surface for workpiece support. It is a standard single-piece component typically installed in toolroom, production, and maintenance-repair-overhaul fixture work.

Key Features

• Press fit design allows direct installation into drilled holes without threading or fasteners
• 52100 steel construction provides high hardness and wear resistance for long service life
• Black oxide finish adds corrosion resistance and reduces light reflection in inspection environments
• Unground surface finish suitable for standard fixturing tolerances
• Compact 3/8 inch OD and 15/32 inch OAL fits common fixture plate configurations
• 0.1885 inch pin diameter for consistent press fit engagement

Compatibility

Designed as a standard press fit rest button for use in precision jigs, fixtures, and workholding assemblies requiring a 3/8 inch outside diameter locating button with a 0.1885 inch press fit pin.

Installation Notes

Installation is performed by toolmakers or machinist trades using an arbor press or similar controlled pressing equipment. The receiving hole in the fixture plate should be sized and toleranced to achieve proper interference fit with the 0.1885 inch pin diameter before pressing the button into place. Do not hammer the button directly without a press plate or driver to avoid damaging the head or distorting the pin. Inspect the seating surface after installation to confirm the button head is flush and fully seated against the fixture body.
