Gibraltar 646460-G Press Fit Rest Button 5/8 Inch Od

Product Description

The GIBRALTAR 646460-G is a ground press fit rest button designed for precision workholding and fixturing applications in industrial and machining environments. Manufactured from low carbon steel with a black oxide finish, this button provides a hardened, ground seating surface that accepts a press-fit installation into a mating bore. It measures 1-3/32 inches in overall length with a 5/8 inch head height and 5/8 inch outside diameter. The 0.376 inch pin diameter ensures a secure interference fit when driven into the host component. Installation is performed by toolmakers, machinists, and fixture builders working with jigs, dies, and precision tooling assemblies.

Press fit rest buttons are used in machine shop and manufacturing environments where a repeatable, wear-resistant contact surface is required. This button is suited for use in drill jigs, inspection fixtures, and machining workholding setups where parts must be located consistently against a ground face. The black oxide coating provides mild corrosion resistance and reduces light reflection on the seating surface. Sold individually with a minimum order quantity of one.

Compatibility

Designed as a standard press fit rest button for use in drill jigs, machining fixtures, and workholding tooling applications requiring a 0.376 inch bore for press fit installation.

Installation Notes

Installation is typically performed by a toolmaker or machinist using an arbor press or hydraulic press to seat the pin into a precision-reamed bore. The bore should be prepared to the appropriate interference fit tolerance before installation. Once pressed in, rest buttons are not intended for repeated removal and reinsertion, as this can damage the bore or reduce retention force. Inspect the mating bore for burrs or debris before pressing the button into place.
