Fairlane HS-765 Round Positioning Gripper 1/4-28 Hss

Product Description

The FAIRLANE HS-765 is a round positioning gripper designed to locate and hold workpieces securely during machining, assembly, and fixture operations. Machined from high speed steel and finished with a black oxide coating for corrosion resistance, this gripper features a coarse-tooth diamond serration pattern that bites into workpiece surfaces to resist shift and rotation under load. The threaded attachment style allows direct installation into fixture plates or tooling bodies using the 1/4-28 thread. At 0.75 inches in diameter and 0.5 inches in height, it is well suited for compact fixture layouts where space is limited.

This gripper is used in precision fixturing, jig and fixture building, and workholding applications across manufacturing and machining environments. The diamond serration tooth pattern is particularly effective in applications requiring positive grip on flat or near-flat workpiece surfaces. A 3/16-inch flat width is provided on the body for wrench engagement during installation and removal. Industrial maintenance technicians and tooling specialists are the primary installers.

Key Features

• Coarse-tooth diamond serration pattern for high grip force on workpiece surfaces
• High speed steel construction for hardness and wear resistance
• Black oxide finish for corrosion resistance and reduced light reflection
• Threaded 1/4-28 attachment for direct installation into fixture bodies
• Compact 0.75-inch diameter and 0.5-inch height for tight fixture layouts
• 3/16-inch flat width for wrench-driven installation and removal

Compatibility

Designed as a threaded replacement or upgrade gripper for round positioning applications in standard fixture plates and tooling bodies accepting a 1/4-28 threaded insert.

Installation Notes

Installation is performed by tooling and fixture specialists using a wrench engaged on the 3/16-inch flat. Ensure the receiving threaded hole is clean and free of debris before threading in the gripper. Do not overtighten, as serrated grippers are designed to function at proper seating depth without excessive torque. Inspect serration teeth for wear or damage during routine fixture maintenance.
