Fairlane HS-75 Round Positioning Gripper 1/4-28 Hss

Product Description

The FAIRLANE HS-75 is a round positioning gripper designed to locate, hold, and secure workpieces during machining, fixturing, and assembly operations. Machined from high speed steel and finished with a black oxide coating for corrosion resistance, this gripper features a fine-tooth diamond serration pattern that bites into workpiece surfaces to resist movement under load. The threaded 1/4-28 attachment style allows direct installation into fixture plates, jigs, and tooling blocks. At 0.75 inches in diameter and 0.38 inches in height, it fits in tight fixture layouts where space is limited. Machinists and tooling engineers working in precision manufacturing environments are the primary installers of this component.

The HS-75 is suited for use in production fixtures, welding positioners, machining jigs, and assembly tooling where repeatable workpiece location is required. The fine diamond serration tooth pattern is appropriate for applications demanding firm grip on flat or lightly contoured surfaces. The 3/16-inch flat width on the serrated face provides consistent contact geometry. This gripper is a threaded-style unit, making it straightforward to install and replace without specialized tooling, which supports fast changeover in high-throughput manufacturing environments.

Key Features

• High speed steel construction provides hardness and wear resistance for long service life in fixture applications
• Fine-tooth diamond serration pattern maximizes grip and resists workpiece slippage under lateral and rotational loads
• Black oxide finish adds surface corrosion resistance without affecting critical dimensions
• Threaded 1/4-28 attachment style allows direct installation into standard fixture plates and tooling blocks
• Compact profile at 0.75 inches diameter and 0.38 inches height fits dense fixture layouts
• 3/16-inch flat width provides consistent serration contact geometry across the gripping face

Compatibility

Designed as a threaded round positioning gripper for use in standard fixture plates, jigs, and tooling blocks with a 1/4-28 threaded hole pattern.

Installation Notes

Installation is performed by tooling engineers or machinists during fixture build or maintenance. Ensure the receiving threaded hole is clean and free of chips or coolant residue before threading the gripper in place. De-energize or lock out any associated machinery before servicing or replacing grippers in active fixtures. Inspect the serration face periodically for wear or loading that may reduce grip effectiveness.
