Gibraltar 9663220 Press Fit Rest Button 52100 Steel

Product Description

The GIBRALTAR 9663220 is a press fit rest button designed for use in workholding, fixturing, and precision machining setups. Manufactured from 52100 steel with a black oxide coating, this rest button provides a hardened, wear-resistant contact surface that supports workpieces during machining operations. It measures 1.219 inches in overall length, with a 7/8 inch outside diameter and a 5/8 inch head height. The unground press fit design allows for straightforward installation into a mating bore without the need for secondary grinding. Machinists and tooling technicians working in production environments rely on rest buttons like this to maintain consistent part positioning and support across repeated cycles.

This rest button is suited for use in jigs, fixtures, and machine tool setups where repeatable workpiece support is required. The 0.501 inch pin diameter is sized for a controlled press fit into a corresponding hole, making it appropriate for applications where the button must remain stationary under load. The black oxide finish provides mild corrosion resistance for shop environments. It is sold individually and is a common component in toolroom and production fixture fabrication.

Key Features

• 52100 steel construction for hardness and wear resistance in contact applications
• Black oxide coating provides mild corrosion protection
• Unground press fit design for direct installation into a mating bore
• 0.501 inch pin diameter sized for controlled press fit retention
• 7/8 inch outside diameter head for stable workpiece support surface
• Sold individually for single-unit replacement or fixture builds

Compatibility

Designed as an OEM-style replacement or direct-use component for standard press fit rest button applications in machining fixtures and workholding assemblies.

Installation Notes

Installation is performed by toolmakers or machinist-level technicians using a press or arbor press to seat the button into a precision-bored hole. Ensure the receiving bore is dimensioned to the correct tolerance for a press fit before installation. Do not hammer the button in directly without a driver block, as this may damage the head face or misalign the button. Remove all workpiece loads and de-energize any associated equipment before servicing fixture components.
