Gibraltar 9663329 Press Fit Rest Button 1-1/4 in Od 52100 Steel

Product Description

The GIBRALTAR 9663329 is a press fit rest button designed for use in precision workholding and fixturing applications. This rest button features a 52100 steel construction with a black oxide coating for corrosion resistance and a clean surface finish. It measures 1.469 inches overall length with a 1-1/4 inch outside diameter and a 5/8 inch head height. The unground press fit type suits applications where tight tolerances are maintained through the press fit interface rather than ground seating surfaces. Installed by machinists, toolmakers, and fixture builders, this button provides a stable, repeatable contact point for supporting workpieces during machining operations.

This rest button is suited for use in machine shop fixtures, jigs, and workholding setups where a hardened steel contact point is required. The press fit design allows secure installation into a bored hole without the need for threading or adhesive. The 0.751 inch pin diameter interfaces with a corresponding bore in the fixture body. It is appropriate for both production and prototype fixturing in environments where wear resistance and dimensional consistency are priorities.

Key Features

• 52100 steel construction for high hardness and wear resistance
• Black oxide coating provides corrosion resistance and a clean appearance
• Unground press fit design for straightforward installation into a bored hole
• 1-1/4 inch outside diameter head for broad workpiece contact area
• 0.751 inch pin diameter for secure press fit retention in fixture body
• Compact 1.469 inch overall length suits space-constrained fixture designs

Compatibility

Designed as an OEM-style replacement or standard component for precision fixturing, jig, and workholding applications requiring a press fit hardened steel rest button.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the pin into a precision bored hole. Ensure the receiving bore diameter matches the 0.751 inch pin diameter to achieve proper press fit retention. Do not hammer the button directly on the head face, as this may damage the seating surface. Inspect the bore for burrs or contamination before pressing the component into place.
