Gibraltar 9810SS Clamping Screw 1/4-20 Stainless Steel

Product Description

The GIBRALTAR 9810SS is a headed, plain flat face, ball end clamping screw designed for secure workholding and fixturing applications. Manufactured from 18-8 stainless steel throughout — both the screw body and the ball end — it resists corrosion in wet or harsh shop environments. The screw features a 1/4-20 UNC thread and measures 1 inch overall length. The ball end diameter is 0.12 inches, providing a low-contact-area clamping point suitable for securing workpieces without marring critical surfaces. A 3/16-inch hex key drives the screw. Machinists, tool-and-die technicians, and fixture builders install this type of fastener in jigs, fixtures, and machine vises.

This clamping screw is suited for use in precision workholding setups found in machine shops, production facilities, and toolmaking environments. The plain flat face ball end style is appropriate for applications where a swiveling contact point is needed to accommodate slight angular misalignment between the screw axis and the clamped workpiece surface. The 1/4-20 UNC thread size makes it compatible with standard fixture plates, toggle clamps, and workholding components machined to common inch-thread standards.

Key Features

• 18-8 stainless steel screw body and ball end for corrosion resistance in demanding shop conditions
• Plain flat face ball end at 0.12 inches diameter provides a low-marring swivel contact point
• 1/4-20 UNC thread for compatibility with standard inch-thread workholding hardware
• 1 inch overall length suits compact fixture and jig designs
• 3/16-inch hex key drive for positive torque engagement
• Headed style for controlled seating and easy removal

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard 1/4-20 UNC threaded workholding fixtures, jigs, and clamping assemblies.

Installation Notes

Installation is performed by machinists or toolmakers using a 3/16-inch hex key. Ensure the mating threaded hole is clean and free of debris before threading the screw in. Do not exceed the torque capacity appropriate for 1/4-20 stainless steel fasteners, as 18-8 stainless is susceptible to galling if driven too aggressively without lubrication. Confirm thread engagement is adequate for the load before placing the fixture into service.
