Gibraltar 64255722 Press Fit Rest Button Hardened Steel

Product Description

The GIBRALTAR 64255722 is a press fit rest button designed for use in fixture and workholding applications where precise, repeatable part location is required. Manufactured from hardened steel with a ground finish, this button provides a stable, wear-resistant contact surface. It measures 3/4 inch overall length, features a 1/4 inch head height, and has a 1/2 inch outside diameter. The 0.251 inch pin diameter allows for a controlled press fit installation into standard tooling plates and fixtures. A black oxide coating adds a layer of corrosion resistance for shop-floor environments. Licensed machinists, tool and die makers, and fixture builders are the typical installers of this component.

Press fit rest buttons like the 64255722 are used in machining fixtures, jigs, and workholding setups across manufacturing environments. The hardened and ground contact surface ensures dimensional stability and long service life under repeated loading. This button is suited for applications where consistent part location height is critical to maintaining tight tolerances. Its ground press fit pin seats securely in a bored hole in the fixture body, eliminating movement during clamping and machining operations.

Key Features

• Hardened steel construction for wear resistance under repeated use
• Ground finish on contact surface ensures precise seating and dimensional accuracy
• Press fit pin diameter of 0.251 inches for secure, interference-fit installation
• Black oxide coating provides corrosion resistance in shop environments
• Compact profile with 1/4 inch head height and 1/2 inch OD suits tight fixture layouts
• Pin length of 1/2 inch provides adequate engagement depth in standard tooling plates

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard press fit rest button applications in machining fixtures, jigs, and workholding tooling plates that accept a 0.251 inch diameter press fit pin.

Installation Notes

Installation is typically performed by a toolmaker or machinist using an arbor press to seat the button into a precision-bored hole in the fixture body. The receiving bore should be sized to the appropriate interference fit for a 0.251 inch press fit pin before installation. Ensure the fixture plate is securely supported during pressing to avoid distortion. Inspect the seating surface for burrs or debris before pressing the button into position.
