Gibraltar 9663063 Press Fit Rest Button 52100 Steel

Product Description

The GIBRALTAR 9663063 is a press fit rest button designed for use in workholding, fixturing, and precision machining setups. It provides a stable, repeatable contact point for locating and supporting workpieces on jigs, fixtures, and machine tool surfaces. Manufactured from 52100 steel with a black oxide finish, this rest button offers solid wear resistance in demanding shop environments. The unground press fit design allows for direct installation into a prepared bore without additional machining. At 15/32 inches overall length with a 1/4 inch outside diameter and a pin diameter of 0.1885 inches, it fits standard rest button bores common in toolroom and production fixturing applications.

This rest button is suited for use in machine shop and manufacturing environments where accurate workpiece location is required. It installs into fixture plates, tombstones, and tooling bodies to support and locate metal parts during milling, drilling, turning, or grinding operations. The press fit design simplifies installation in production fixturing where fast, reliable seating is needed. It is typically specified by toolmakers, fixture designers, and CNC machinists working on close-tolerance setups in both job shop and high-volume production settings.

Key Features

• 52100 steel construction provides high hardness and wear resistance for long service life in abrasive contact applications
• Black oxide finish offers mild corrosion resistance and reduces light reflection in precision work environments
• Unground press fit design for straightforward installation into a matching bore without additional preparation
• 0.1885 inch pin diameter for repeatable, close-tolerance press fit seating in standard fixture bores
• Compact 15/32 inch overall length suits low-profile fixturing applications with tight clearance requirements

Compatibility

Designed as an OEM-style replacement or standard component for press fit rest button applications in industrial fixtures, jigs, and tooling plates requiring a 1/4 inch outside diameter rest button with a 0.1885 inch pin diameter.

Installation Notes

Rest buttons are typically installed by toolmakers or fixture technicians using a press or arbor press to seat the pin into a precision-bored hole. Ensure the receiving bore is clean, within tolerance, and free of burrs before pressing the button into place. Do not use a hammer to drive the button, as this can damage the seating surface or distort the bore. Verify workpiece contact surface condition after installation to confirm proper seating and location accuracy.
