Gibraltar 30505MG Steel Clamp Strap M12 Stud Tapered Nose

Product Description

The GIBRALTAR 30505MG is a steel clamp strap designed for workholding applications on milling machines, drill presses, and similar machine tool setups. The strap features a tapered nose profile and a plain heel, with a serrated clamping surface that helps resist slippage under load. It is built from 1018 steel with a black finish for basic corrosion resistance. The M12 stud size is compatible with standard T-slot clamping hardware. With a 33 mm travel range and an overall length of 102 mm, this strap suits a range of workpiece heights and setups. Machinists and tool-and-die professionals install these as part of modular step-block and stud clamping sets.

This clamp strap is used in manual and CNC machine tool environments where positive, rigid workholding is required. Typical applications include fixturing flat plate workpieces, castings, and irregularly shaped parts on mill tables or surface grinder magnetic chucks supplemented with mechanical clamps. The tapered nose design allows the strap to angle down toward the workpiece for increased clamping force distribution. This part is sold individually and is compatible with M12 threaded studs and standard step blocks used in modular clamping systems.

Key Features

• Tapered nose profile directs clamping force toward the workpiece for secure hold
• Serrated underside resists strap rotation and slippage during setup
• Plain heel for use with standard step blocks or riser combinations
• 1018 steel construction provides reliable strength for typical machining loads
• Black finish for surface protection in shop environments
• M12 stud size fits standard modular T-slot clamping hardware

Compatibility

Designed as a direct-fit replacement or supplemental component for modular M12 stud T-slot clamping sets used on standard machine tool tables.

Installation Notes

Installation is performed by machinists or tooling technicians as part of workholding setup. Power down and de-energize the machine before configuring any fixturing on the table. The stud should be positioned in the T-slot and tightened with appropriate tooling to secure the workpiece without distortion. Verify that the step block or riser height matches the workpiece surface before applying final clamping torque to avoid uneven loading.
