Gibraltar 9663311 Press Fit Rest Button 52100 Steel

Product Description

The GIBRALTAR 9663311 is a press fit rest button designed for use in workholding, fixturing, and precision machining applications. This button provides a stable, repeatable seating surface for workpieces on jigs, fixtures, and machine tables. Manufactured from 52100 steel with a black oxide finish, it delivers hardness and corrosion resistance suited to production shop environments. Key dimensions include an overall length of 1.344 inches, a head height of 0.5 inches, an outside diameter of 1.25 inches, and a pin diameter of 0.751 inches. The unground press fit design allows for straightforward installation without secondary machining of the button itself.

Rest buttons of this type are used in metal fabrication, tool-and-die, and precision machining shops. They are pressed into pre-drilled holes in fixture plates or jig bodies to create controlled contact points that locate and support workpieces during milling, drilling, grinding, or inspection operations. The 52100 steel construction makes this button appropriate for high-contact, wear-intensive fixturing environments where dimensional stability is critical.

Key Features

• 52100 steel construction for high hardness and wear resistance in production fixturing
• Black oxide finish provides mild corrosion resistance and reduces light reflection on the shop floor
• Unground press fit design for straightforward installation into a prepared bore
• 1.25 inch outside diameter with 0.751 inch pin diameter for secure press fit retention
• Overall length of 1.344 inches with a 0.5 inch head height for consistent workpiece contact elevation

Compatibility

Designed as an OEM-style replacement or direct-use component for standard press fit rest button applications in precision fixturing, jig plates, and workholding assemblies requiring a 1.25 inch OD button with a 0.751 inch pin diameter.

Installation Notes

Press fit rest buttons are typically installed by toolmakers or machinist technicians using an arbor press or hydraulic press. The receiving bore in the fixture plate must be machined to the appropriate interference fit tolerance before installation. Do not hammer the button directly without a proper press tool, as this may damage the head seating surface or misalign the pin. Ensure the fixture assembly is fully de-energized and cleared of workpieces before servicing or replacing rest buttons.
