Fairlane CTH-0375-EF Positioning Gripper 3/8-16 Hex Head

Product Description

The FAIRLANE CTH-0375-EF is a hex-head adjustable positioning gripper designed to locate, hold, and secure workpieces during machining, assembly, and fixture operations. The gripper features a carbide-tipped, serrated tooth pad in an extra-fine tooth pattern that bites into workpiece surfaces to prevent lateral movement without damaging finished parts. The 3/8-16 threaded shank makes it compatible with standard fixture plates and tooling blocks. With a 1-inch shank length and 1-inch thread length, the CTH-0375-EF fits into a range of standard fixture setups. A black oxide finish provides corrosion resistance in shop environments. Machinists, toolmakers, and fixture builders are the primary installers.

The CTH-0375-EF is used in precision machining and manufacturing environments where repeatable workpiece positioning is required. It is suited for installation in jigs, fixtures, and workholding assemblies across production machining, assembly line, and quality control stations. The adjustable design allows the gripper pad angle to be set to match irregular or angled workpiece surfaces, making it practical for both flat and contoured part holding. This gripper is typically used in light to medium industrial fixturing applications.

Key Features

• Carbide-tipped pad provides long service life in high-cycle fixturing applications
• Extra-fine serrated tooth pattern grips workpiece surfaces firmly while minimizing surface damage
• Adjustable pad angle accommodates flat and contoured workpiece geometries
• 3/8-16 thread size fits standard fixture plates and tooling blocks
• Black oxide finish resists corrosion in coolant-exposed shop environments
• Hex head design allows torque application with standard wrenches using the 9/16-inch hex

Compatibility

Designed as an OEM-style replacement or direct-fit component for fixtures and workholding assemblies that accept 3/8-16 threaded positioning grippers with a hex-head drive style.

Installation Notes

Installation is performed by machinists or toolmakers during fixture build or maintenance. Thread the gripper into the fixture plate by hand first to avoid cross-threading, then torque using a standard wrench on the 9/16-inch hex head. Ensure the fixture assembly is fully de-energized and any clamping pressure is released before replacing or adjusting grippers in an active workholding setup. Do not overtighten, as carbide-tipped pads are brittle and susceptible to cracking under excessive side load or impact.
