Gibraltar 9663295 Press Fit Rest Button 52100 Steel

Product Description

The GIBRALTAR 9663295 is a press fit rest button designed for use in workholding and fixture applications. It provides a stable, repeatable contact point for locating and supporting workpieces on jigs, fixtures, and machine tables. Manufactured from 52100 steel with a black oxide finish, this rest button offers good wear resistance and corrosion protection in typical shop environments. The unground press fit design allows for straightforward installation into a prepared bore. Key dimensions include an overall length of 1.219 inches, a 3/8-inch head height, and a 1-1/4-inch outside diameter, making it suitable for medium-duty fixturing work.

This rest button is used in industrial manufacturing and machining environments where precise workpiece positioning is required. It is commonly installed in fixture plates, tombstones, and modular workholding systems. The press fit retention method eliminates the need for threaded fasteners, simplifying fixture assembly. Toolmakers, machinists, and fixture builders typically specify this type of rest button for both production and prototype fixturing setups.

Key Features

• Press fit installation for secure, fastener-free retention in prepared bores
• 52100 steel construction for wear resistance in contact-surface applications
• Black oxide finish provides mild corrosion protection
• Unground head surface suits standard fixture locating applications
• 0.751-inch pin diameter for consistent bore fit
• Compact head profile with 3/8-inch head height minimizes fixture stack-up

Compatibility

Designed as an OEM-style replacement or direct fitment for press fit rest button applications in standard industrial fixturing and workholding systems where a 1-1/4-inch OD and 0.751-inch pin diameter are specified.

Installation Notes

Installation is performed by toolmakers or machinists using a press or arbor press to seat the pin into a correctly sized and toleranced bore. Ensure the receiving bore is clean and within the specified tolerance for the press fit before installation. The workpiece or fixture plate should be properly supported during pressing to avoid distortion. Do not hammer the button directly on the head surface, as this may damage the contact face.
