Gibraltar 9663261 Press Fit Rest Button 52100 Steel

Product Description

The GIBRALTAR 9663261 is a press fit rest button designed for use in workholding, fixturing, and precision machine tool applications. Machined from 52100 chrome steel with an unground press fit shank, this rest button provides a stable, repeatable seating surface for workpieces in jigs and fixtures. It carries a black oxide coating for corrosion resistance and reduced glare on the working surface. Key dimensions include a 1.219-inch overall length, a 1-inch outside diameter head, a 1/2-inch head height, and a 0.626-inch pin diameter. Weighing 0.17 pounds, it ships as a single-piece unit.

Rest buttons like the 9663261 are installed in tool and die shops, precision machining facilities, and production fixturing environments. The press fit design allows the button to be driven directly into a bored hole in a fixture plate or tooling body without the need for threaded fasteners. The unground shank finish is suitable for standard tolerance press fit bores. Installation is typically performed by tool and die makers or machining technicians during fixture build or maintenance operations.

Key Features

• 52100 chrome steel construction for high hardness and wear resistance
• Black oxide coating provides corrosion resistance and reduces light reflection
• Unground press fit shank for standard tolerance bore installations
• 1-inch outside diameter head with 1/2-inch head height for a broad seating surface
• 0.626-inch pin diameter for positive press fit retention in fixture plates
• Single-piece unit with no additional hardware required

Compatibility

Designed as an OEM-style replacement or new-build component for standard press fit rest button applications in machining fixtures, jigs, and tooling plates requiring a 0.626-inch press fit bore.

Installation Notes

Installation is performed by tool and die makers or machining technicians. The receiving bore in the fixture plate should be sized to the appropriate press fit tolerance for the 0.626-inch pin diameter before driving the button into place. Use a proper arbor press or hydraulic press to seat the button squarely and avoid damage to the head seating surface. Inspect the bore for burrs or contamination before installation to ensure accurate seating.
