Gibraltar 85549947 Counterbored Rest Button Steel

Product Description

The GIBRALTAR 85549947 is a counterbored rest button manufactured from heat treated steel with a black oxide finish. Rest buttons are precision workholding components used to locate and support workpieces in fixtures, jigs, and machining setups. The counterbored design allows the button to seat flush or recessed within a fixture body, providing a stable, repeatable contact surface. With an overall length of 1 inch and an outside diameter of 7/8 inch, this button suits close-tolerance fixture work where consistent part location is critical. The heat treated steel construction provides hardness and wear resistance appropriate for production-volume fixture use.

This rest button is suited for use in machine shop and manufacturing environments where toolmakers and fixture designers require reliable workpiece support. It is commonly installed in drill fixtures, milling fixtures, and inspection fixtures across light to medium industrial applications. The black oxide finish provides a degree of corrosion resistance while maintaining dimensional integrity on the contact surfaces. At 0.02 pounds, the part is lightweight and easy to handle during fixture assembly.

Key Features

• Counterbored design allows flush or recessed mounting within fixture bodies
• Heat treated steel construction for hardness and wear resistance in production use
• Black oxide finish for corrosion resistance and surface protection
• 1 inch overall length with 7/8 inch outside diameter for close-tolerance fitment
• Lightweight at 0.02 pounds for easy handling during fixture assembly

Compatibility

Designed as an OEM-style workholding component for use in standard toolmaker fixtures, jigs, and machining setups requiring a counterbored rest button with 7/8 inch outside diameter.

Installation Notes

Installation is typically performed by toolmakers or fixture designers during fixture assembly or maintenance. Power down and lock out all associated machinery before servicing any fixture containing this component. Use appropriate press-fit or threaded installation methods as specified by the fixture design. Avoid impact installation methods that could damage the precision contact surface of the button.
