Fairlane HS-76 Round Positioning Gripper 1/4-28 Hss

Product Description

The FAIRLANE HS-76 is a round positioning gripper designed to locate and hold workpieces securely during machining, fixturing, and assembly operations. Manufactured from high speed steel with a black oxide coating, this gripper delivers hardness and wear resistance suited for repeated use in production environments. It features a coarse tooth grade diamond serration tooth pattern that bites into workpiece surfaces to resist slipping under load. The threaded attachment style uses a 1/4-28 thread for direct installation into fixture plates, jigs, and tooling blocks. At 0.75 inches in diameter and 0.38 inches in height, it fits compact fixture layouts without sacrificing grip performance. Machinists, toolmakers, and fixture builders are the primary installers.

This gripper is used in workholding fixtures, locating nests, and precision assembly jigs across both light and heavy manufacturing. The diamond serration pattern is suited for applications where axial and rotational slip resistance are both required. The black oxide finish provides moderate corrosion resistance for shop floor conditions. The 3/16 inches flat width allows engagement with a wrench or driver during installation. It is sold individually and is a direct threaded installation into prepared fixture holes.

Key Features

• High speed steel construction for hardness and long service life in repetitive workholding use
• Coarse tooth grade diamond serration pattern resists both axial and rotational workpiece movement
• 1/4-28 threaded attachment for direct installation into fixture plates and tooling blocks
• Black oxide coating provides corrosion resistance in standard shop environments
• Compact 0.75 inches diameter by 0.38 inches height fits tight fixture layouts
• 3/16 inches flat width for wrench engagement during installation and removal

Compatibility

Designed for use in standard fixture plates, jigs, and tooling assemblies that accept a 1/4-28 threaded locating component. Suitable for workholding applications requiring a round, threaded positioning gripper with diamond serration.

Installation Notes

Installation is performed by toolmakers or fixture builders using a standard wrench sized to the 3/16 inches flat. Thread the gripper into a prepared 1/4-28 tapped hole in the fixture plate to the appropriate seating depth. Ensure the mating tapped hole is clean and free of chips or debris before installation. Disengage all power and secure the workpiece fixture before servicing or replacing grippers in active production tooling.
