Gibraltar 9518-G Headless Clamping Screw 5/8-11 Unc

Product Description

The GIBRALTAR 9518-G is a headless clamping screw designed for workholding and fixturing applications in machining and fabrication environments. The screw features a plain flat face ball end that allows it to apply clamping force at an angle without marring the workpiece surface. Built from steel with a black oxide finish, the 9518-G measures 1 inch overall length and is threaded 5/8-11 UNC. The ball itself is stainless steel, adding corrosion resistance at the contact point. This style of clamping screw is a standard component in tooling plates, vises, clamps, and modular fixturing systems.

The 9518-G is suited for use in machine shops, tool rooms, and production environments where repeatable clamping setups are required. It fits into any threaded fixture component or clamping body that accepts a 5/8-11 UNC clamping screw. The headless design keeps the screw profile low, which is important in tight fixturing arrangements. The flat face ball end accommodates slight angular misalignment during clamping, reducing the chance of point loading on the workpiece.

Key Features

• Headless design for low-profile fixturing configurations
• Plain flat face ball end accommodates angular misalignment without marring workpieces
• Steel body with black oxide finish for corrosion resistance in shop environments
• Stainless steel ball for added durability at the contact point
• 5/8-11 UNC thread standard for broad compatibility with standard fixturing hardware
• 1 inch overall length suits compact clamping applications

Compatibility

Designed as an OEM-style replacement or direct-fit component for threaded fixturing assemblies, tooling plates, and clamping bodies that accept 5/8-11 UNC headless clamping screws.

Installation Notes

Installation is performed by machinists or tooling technicians using a hex key or spanner wrench sized for the headless socket. De-energize any powered fixturing or clamping systems before servicing. Avoid over-torquing, which can deform the ball seat or damage the mating thread in softer fixture materials. Inspect the ball end and thread condition before each use in precision clamping applications.
