Fairlane HS-82 Round Positioning Gripper 1in 1/4-28

Product Description

The FAIRLANE HS-82 is a round positioning gripper designed to hold and locate workpieces accurately during machining, assembly, and fixture operations. Constructed from high speed steel with a black oxide finish, this gripper features a fine tooth diamond serration pattern that bites into workpiece surfaces to resist slipping and lateral movement. It threads directly into a tapped hole using a 1/4-28 thread, making installation fast and repeatable. At 1 inch in diameter and 3/8 inch in height, it fits into compact fixture layouts without interfering with surrounding components. Machinists, toolmakers, and fixture builders rely on this style of gripper for consistent part registration.

The HS-82 is suited for use in jigs, fixtures, and workholding setups across light to medium industrial applications. It is commonly installed in precision machining environments where part slippage during milling, drilling, or inspection is a concern. The threaded attachment style allows it to be secured directly into fixture plates or modular tooling components with a standard 1/4-28 tapped hole. The 3/16 inch flat width accommodates installation and removal with standard tooling.

Key Features

• Fine tooth diamond serration pattern provides strong grip and accurate part registration
• High speed steel construction delivers hardness and wear resistance in demanding fixture applications
• Black oxide finish reduces surface corrosion and light reflectivity
• 1/4-28 threaded attachment mounts directly into standard tapped fixture holes
• Compact 1 inch diameter and 3/8 inch height fits tight fixture layouts
• 3/16 inch flat width allows installation and removal with common hand tools

Compatibility

Designed as a threaded round positioning gripper for use in jigs, fixtures, and workholding plates with a 1/4-28 tapped mounting hole.

Installation Notes

Installation is performed by toolmakers or fixture technicians using hand tools sized to the 3/16 inch flat width. Ensure the receiving fixture plate is tapped to a clean 1/4-28 thread before installation. Secure the workpiece or power down any associated equipment before servicing or replacing grippers in a live fixture. Do not over-torque, as high speed steel components can be damaged by excessive clamping force.
