Fairlane HS-50-C-EF Round Positioning Gripper Hss

Product Description

The FAIRLANE HS-50-C-EF is a round positioning gripper designed to locate and hold workpieces during machining, assembly, or fixturing operations. Manufactured from high speed steel with a black oxide finish, this gripper measures 0.5 inches in diameter and 0.38 inches in height. It features an extra fine diamond serration tooth pattern that bites into workpiece surfaces to resist lateral movement and rotation. The counterbored design accepts a No. 8 socket head cap screw for front-mount installation, keeping the fastener recessed and out of the work envelope. Machinists, toolmakers, and fixture builders install this component in jigs and fixtures where repeatable part positioning is required.

The HS-50-C-EF is suited for use in production jigs, assembly fixtures, and precision workholding setups where a compact, front-mounted gripper is needed. The 0.5-inch diameter footprint fits tight-tolerance fixture plates and modular tooling systems. The extra fine tooth grade makes this gripper appropriate for softer workpiece materials or applications where aggressive serrations would mar a finished surface. It is installed individually or in arrays to constrain parts in multiple directions.

Key Features

• Extra fine diamond serration tooth pattern for controlled grip without excessive surface damage
• High speed steel construction for hardness and wear resistance in demanding fixture environments
• Black oxide finish for corrosion resistance and reduced light reflection on the fixture floor
• Counterbored mounting accepts a No. 8 socket head cap screw for clean front-mount installation
• Compact 0.5 inch diameter by 0.38 inch height fits space-constrained fixture designs

Compatibility

Designed as an OEM-style positioning gripper for use with No. 8 socket head cap screws in front-mount fixture and workholding applications.

Installation Notes

Installation is typically performed by toolmakers or machinist personnel during fixture build or maintenance. Before installing or replacing grippers in an active fixture, ensure the fixture is removed from the machine and all clamping pressure is fully released. Use the appropriately sized hex key for the No. 8 socket head cap screw and tighten to the fixture designer's specified torque. Inspect the serration contact surface periodically for wear or loading that could compromise positioning repeatability.
