Fairlane SRP-755-C Counterbored Rest Button Steel

Product Description

The FAIRLANE SRP-755-C is a counterbored rest button used as a precision locating and support component in fixturing, tooling, and workholding applications. Machined from steel with a black oxide finish, this round button provides a hardened, stable contact point for workpiece positioning. It measures 0.5 inches overall length with a 0.75 inch outside diameter. The counterbored design allows for recessed fastener mounting, keeping the seating surface clean and unobstructed. Toolmakers, machine operators, and fixture builders install these buttons where repeatable, accurate part location is required on jigs and fixtures.

This rest button is suited for use in precision machining environments, including CNC fixturing, inspection fixtures, and manual machine setups. The compact 0.5 inch OAL and 0.75 inch OD make it appropriate for applications where space is limited but a reliable, flat contact surface is needed. The black oxide finish provides mild corrosion resistance while maintaining dimensional integrity.

Key Features

• Counterbored design allows recessed fastener mounting for a flush, unobstructed seating surface
• Steel construction for durability in industrial fixturing applications
• Black oxide finish for mild corrosion resistance
• Round shape with 0.75 inch outside diameter
• Compact 0.5 inch overall length suits tight fixturing layouts

Compatibility

Designed as a standard counterbored rest button for use in industrial jigs, fixtures, and workholding systems requiring a steel locating contact point.

Installation Notes

Rest buttons are typically installed by toolmakers or machinist-level technicians during fixture build or maintenance. Ensure the mounting bore is clean and sized correctly for the button shank before pressing or fastening into place. Secure the button using the counterbored fastener hole, and verify the seating surface is flush and free of burrs or debris before locating a workpiece. Deburr mating surfaces as needed to maintain accurate positioning.
