Gibraltar 9519SS-G Headless Ball End Clamping Screw 5/8-11

Product Description

The GIBRALTAR 9519SS-G is a headless, plain flat face ball end clamping screw designed for workholding and fixturing applications in machining and manufacturing environments. The screw features a 5/8-11 UNC thread and measures 1.5 inches overall length, with a 0.372-inch diameter stainless steel ball end that contacts the workpiece. Constructed from 18-8 stainless steel, it resists corrosion in coolant-rich or washdown environments. This style of clamping screw is typically installed by machinists, toolmakers, and fixture builders where a smooth, rotating contact point is needed to avoid marring or shifting a workpiece during clamping operations.

The 9519SS-G suits a wide range of fixturing setups including drill jigs, milling fixtures, and modular workholding systems. The headless design allows the screw to sit flush or below the fixture surface, keeping the clamping profile low and out of the tool path. The plain flat face ball configuration provides stable, point contact clamping pressure. This screw is a standard component in industrial tooling assemblies and is well suited to both production-run and job-shop environments where corrosion resistance and durability matter.

Key Features

• Headless design keeps clamping profile low and clear of cutting tools
• Plain flat face ball end provides stable point contact without marring workpieces
• 18-8 stainless steel construction resists corrosion from coolants and washdown
• 5/8-11 UNC thread for compatibility with standard fixture and jig components
• 0.372-inch ball diameter for consistent contact geometry
• 1.5-inch overall length suits typical fixture plate and block applications

Compatibility

Designed as a standard UNC-threaded clamping screw for use in machining fixtures, drill jigs, and modular workholding systems requiring a 5/8-11 threaded ball end clamping element.

Installation Notes

Installation is performed by machinists or toolmakers using a hex key or spanner suited to headless set screws. Ensure the mating threaded hole is clean and free of chips or debris before threading in the screw. Apply appropriate thread lubricant or anti-seize when installing stainless fasteners into stainless or steel blocks to prevent galling. Do not overtighten; set clamping torque based on fixture design requirements and workpiece material.
