Fairlane SRP-75-C Counterbored Rest Button Steel

Product Description

The FAIRLANE SRP-75-C is a counterbored rest button used as a precision workpiece contact point in fixturing, tooling, and machining setups. Machined from steel with a black oxide finish, this round button provides a stable, hardened rest surface that locates or supports parts during milling, drilling, or inspection operations. With an overall length of 0.375 inches and an outside diameter of 0.75 inches, it fits standard counterbored mounting holes and sits flush or below the surface of a fixture plate when installed. Tool and die makers, fixture builders, and machine shop technicians are the primary installers.

The SRP-75-C is suited for use in jigs, fixtures, and workholding assemblies across general machining, fabrication, and quality control environments. The counterbored design allows the button to be secured with a fastener that seats below the contact face, keeping the mating surface clean and unobstructed. Typical applications include locating pads on drill jigs, support points on milling fixtures, and rest surfaces on inspection fixtures in both job shop and production environments.

Key Features

• Counterbored design allows fastener head to sit below the working face
• Steel construction provides durability and wear resistance in high-contact applications
• Black oxide finish reduces surface corrosion and light reflection
• Round profile with 0.75 inch OD suits standard fixture plate counterbore patterns
• Compact 0.375 inch overall length fits low-profile fixturing layouts

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard counterbored rest button applications in steel jig and fixture assemblies.

Installation Notes

Rest buttons are typically installed by tool and die makers or machining technicians using a press fit or fastener through the counterbored hole. Ensure the mating counterbore in the fixture plate matches the button OD and depth before installation. De-energize or lock out any associated machine before servicing fixtures. Do not force buttons into undersized bores, as this can compromise location accuracy.
