Gibraltar 30508G Clamp Strap Steel 5/8 in Stud Tapered Nose

Product Description

The GIBRALTAR 30508G is a steel clamp strap designed for workholding applications in machining, fabrication, and general industrial setups. Built from 1018 steel with a black finish, this strap features a tapered nose and serrated heel for secure, consistent clamping. It accommodates a 5/8-inch stud and provides 1-3/16 inches of travel along its slotted channel. At 4 inches overall length and 1.13 pounds, it suits standard T-slot tables, milling machine tables, and similar fixturing surfaces. Licensed machinists, toolmakers, and fabricators install this type of strap as part of a complete workholding setup.

The 30508G is suited for use on milling machines, drill presses, and fabrication fixtures where repeatable clamping pressure and positive part retention are required. Its serrated heel resists rocking under load, and the tapered nose profile allows close approach to workpiece edges. At 1-1/2 inches wide and 3/4 inches high, it fits compact setups where clearance is limited. This strap is typically used in job shops, maintenance facilities, and light manufacturing environments.

Key Features

• Tapered nose for close approach to workpiece edges
• Serrated heel resists rocking and shifting under clamping load
• 1018 steel construction for reliable strength in standard workholding applications
• 1-3/16 inches of travel accommodates varying workpiece and step block heights
• Black finish provides basic corrosion resistance for shop environments
• Non-tapped design for use with standard stud-and-nut workholding hardware

Compatibility

Designed as an OEM-style replacement or direct-use clamp strap for standard 5/8-inch stud workholding systems on T-slot milling tables, drill press tables, and similar fixturing surfaces.

Installation Notes

Clamp straps of this type are installed by machinists or fabricators as part of a stud-and-nut workholding assembly. Ensure the T-slot table and stud are clean and free of chips before assembly. Use a torque wrench appropriate for the stud size and follow the machine manufacturer guidelines for maximum clamping force. Never exceed the travel range of the slot, as doing so can reduce clamping effectiveness and risk part movement during operation.
