Gibraltar 9512SS-G Ball End Clamping Screw 5/16-18 Ss

Product Description

The GIBRALTAR 9512SS-G is a headless plain flat face ball end clamping screw designed for workholding, fixturing, and positioning applications in industrial and mechanical assemblies. Threaded 5/16-18 UNC with an overall length of 0.75 inches, this screw features an 18-8 stainless steel body and a stainless steel ball tip measuring 0.147 inches in diameter. The headless design allows the screw to seat flush or below surface level, making it suitable for close-tolerance assemblies where a protruding head would interfere with adjacent components. A 5/32-inch hex key is used for installation and adjustment.

This clamping screw is commonly used in machine tool setups, jigs, fixtures, and precision workholding equipment. The flat face ball end provides a consistent contact point against workpieces or locking surfaces without marring. It is well suited for applications where repeated adjustment is required and corrosion resistance is a priority, such as wet or washdown environments in manufacturing, food processing, or marine-adjacent settings.

Key Features

• Headless design seats flush or sub-flush for low-profile installations
• Plain flat face ball tip provides consistent, non-marring contact
• 18-8 stainless steel body and ball for corrosion resistance
• 5/16-18 UNC thread for broad fixture and tooling compatibility
• 5/32-inch hex key drive for easy torque application in tight spaces
• 0.75 inch OAL suits compact clamping assemblies

Compatibility

Designed as a standard 5/16-18 UNC headless ball end clamping screw for use in workholding fixtures, jigs, and mechanical positioning assemblies requiring a flush-mount, corrosion-resistant fastener.

Installation Notes

Installation is performed with a 5/32-inch hex key. Ensure the mating threaded hole is clean and free of debris before threading in the screw. Power down or de-energize any associated machinery before adjusting clamping elements in a live fixture. Do not over-torque stainless steel fasteners, as galling can occur; use appropriate anti-seize compound if repeated removal is anticipated.
