Fairlane HS-955-EF Square Positioning Gripper 10-32 Hss

Product Description

The FAIRLANE HS-955-EF is a square positioning gripper designed to hold workpieces securely during machining, assembly, or fixturing operations. Measuring 0.5 inches square and 0.5 inches high, this gripper features a 10-32 threaded shank for mounting into fixture plates and tooling blocks. The cutting face uses a diamond serration pattern in an extra fine tooth grade, providing firm, repeatable grip on a wide range of part materials. Constructed from high speed steel with a black oxide finish, the HS-955-EF offers good wear resistance and corrosion protection in shop environments. A 0.03 x 45-degree chamfer on the face eases initial part contact and seating.

Square positioning grippers like the HS-955-EF are used in precision fixturing, jig and fixture building, and production machining setups where consistent part location and anti-slip retention are required. They are a standard component in modular fixture systems and custom tooling plates across general machining, metalworking, and light manufacturing environments. Machinists, toolmakers, and fixture engineers install these grippers in production and prototype fixturing applications.

Key Features

• Diamond serration pattern provides multi-directional grip on workpiece surfaces
• Extra fine tooth grade suits applications requiring minimal surface marking and precise seating
• High speed steel construction delivers hardness and wear resistance for repeated use
• Black oxide finish adds corrosion resistance and reduces light reflection in the work area
• 10-32 threaded shank fits standard fixture plate thread inserts
• 0.03 x 45-degree chamfer on face eases part loading and reduces edge interference

Compatibility

Designed as a direct-mount positioning gripper for fixture plates, tooling blocks, and modular fixturing systems that accept 10-32 threaded inserts.

Installation Notes

Installation is performed by toolmakers or machinists using standard hex drivers or spanners appropriate for the 10-32 thread. Ensure the mating threaded hole in the fixture plate is clean and free of chips before installation. Do not overtighten, as thread damage can affect seating accuracy and grip face alignment. Verify gripper face orientation relative to the workpiece contact surface before locking down the fixture assembly.
