Gibraltar 9663089 Press Fit Rest Button 52100 Steel

Product Description

The GIBRALTAR 9663089 is a press fit rest button designed for use in precision workholding and fixturing applications. Manufactured from 52100 chrome steel with a black oxide coating, this button provides a hardened, wear-resistant contact surface for locating and supporting workpieces on jigs, fixtures, and machine tool setups. The 9663089 measures 19/32 inches in overall length with a 3/8 inch head height, a 3/8 inch outside diameter, and a pin diameter of 0.1885 inches. The unground press fit design allows for straightforward installation without the need for precision grinding after seating. Machinists, toolmakers, and fixture builders are the primary installers of this component.

This rest button is suited for use in manufacturing and machining environments where consistent workpiece support and location are required. It is appropriate for light to medium-duty fixturing on milling machines, drill presses, and dedicated production fixtures. The black oxide coating provides mild corrosion resistance during storage and normal shop use. The compact dimensions make it well suited for close-tolerance fixture layouts where space between locating features is limited.

Installation Notes

Press fit rest buttons are typically installed by toolmakers or machinists using an arbor press or similar controlled-force pressing equipment. The receiving bore should be sized to the pin diameter tolerance specified by the fixture design before installation. Do not drive the button with a hammer, as uneven force can damage the seating bore or cock the button out of perpendicular. Ensure the fixture plate or component is fully supported and secured during the press-fit operation.
