Gibraltar 9514-G Headless Clamping Screw 3/8-16 Unc

Product Description

The GIBRALTAR 9514-G is a headless, plain flat face ball end clamping screw designed for workholding and fixturing applications in machining and tooling setups. Threaded 3/8-16 UNC with an overall length of 0.75 inches, this screw provides reliable clamping force through a 0.192-inch stainless steel ball end that seats against workpieces without marring or damaging surfaces. The headless design allows flush or recessed installation in fixture plates, jigs, and clamp bodies. A black oxide finish provides mild corrosion resistance in shop environments. Machining professionals and tooling specialists are the primary installers.

This clamping screw is used in industrial workholding fixtures, jigs, and tooling plates where a compact, headless fastener is required to exert point contact clamping force. The plain flat face ball end is suited for applications where the contact point must conform slightly to angled or uneven workpiece surfaces without gouging. Typical install scenarios include CNC machine fixtures, drill jigs, and manual milling setups in both production and job-shop environments.

Key Features

• Headless design allows flush or below-surface installation in fixture bodies
• Plain flat face ball end in stainless steel minimizes workpiece marring at the contact point
• 3/8-16 UNC thread provides broad compatibility with standard fixture plates and clamp hardware
• Black oxide finish offers mild corrosion and wear resistance in shop conditions
• Compact 0.75-inch overall length suits tight-clearance fixturing applications

Compatibility

Designed as an OEM-style replacement or direct-fit clamping fastener for standard 3/8-16 UNC threaded fixture plates, jig bodies, and workholding clamp assemblies.

Installation Notes

Installation is performed by machinists or tooling technicians using a hex key or Allen wrench sized to the internal drive of the screw. Ensure the mating threaded bore is clean and free of debris before threading in the screw. Do not overtighten, as the stainless steel ball end can be damaged by excessive torque applied against hard workpiece surfaces. De-energize or lock out any powered fixturing equipment before adjusting or replacing clamping screws in an active setup.
