Gibraltar 30506MG Clamp Strap Steel M12 Stud

Product Description

The GIBRALTAR 30506MG is a steel clamp strap designed for workholding and fixturing applications in machining and fabrication environments. It features a tapered nose profile and an M12 stud size, making it a direct-fit component for standard clamp strap setups. The strap is serrated along its contact surface to improve grip and resist slippage under load. With an overall length of 152 mm, a travel of 52 mm, and a width of 32 mm, this strap suits a range of workholding configurations on milling machines, drill presses, and manual machining centers. It weighs 0.25 pounds and carries a black finish. Machinists, toolroom technicians, and setup crews are the primary installers.

This clamp strap is suited for manual and CNC machining fixture setups where an M12 stud is the fastening standard. The tapered nose allows it to reach over workpiece edges and irregular profiles, while the plain heel rests against a step block or riser. It is commonly used in job shop environments, maintenance departments, and production machine shops that require reliable, adjustable workholding without custom tooling. The 52 mm of travel provides flexibility across a useful range of workpiece heights.

Key Features

• Tapered nose profile for reaching over workpiece edges and irregular surfaces
• Serrated contact surface resists slippage under clamping load
• M12 stud size fits standard workholding stud kits
• 1018 steel construction provides toughness for repeated machining use
• Black finish for corrosion resistance in typical shop environments
• Plain heel design compatible with step blocks and riser systems

Compatibility

Designed as an OEM-style replacement or direct addition to standard M12 workholding clamp strap sets used on milling machines, drill presses, and general machining fixtures.

Installation Notes

Installation is performed by machinists or toolroom technicians as part of a workholding setup. Always de-energize and lock out the machine before adjusting or installing clamp straps on the work table. Position the step block and riser to keep the strap as level as possible, placing the stud closer to the workpiece than the step block to maximize clamping force. Torque the stud nut per the fixture manufacturer or shop standard procedure for M12 fasteners.
