Gibraltar 30957G Clamp Strap 25/32 in Stud Tapered Nose

Product Description

The GIBRALTAR 30957G is a carbon steel clamp strap designed to secure workpieces on milling machines, drill presses, and similar machine tool setups. Built from C-1018 carbon steel with a black finish, it provides reliable clamping force through a 3/4-10 tapped stud hole compatible with standard T-slot hardware. The strap measures 6 inches in overall length, 1.5 inches wide, and 1 inch high, with a tapered nose profile that allows it to reach into tighter clamping positions. This part is typically installed by machinists and tool-and-die professionals setting up workholding configurations.

This clamp strap suits standard machine tool workholding applications in both job shop and production environments. The tapered nose design allows the strap to bridge steps between the workpiece and a step block, distributing clamping load effectively. With 1.5 inches of travel and a stud size of 25/32 inch, it fits into common T-slot clamping kits used on manual mills and drill press tables. It is sold individually and is appropriate for both maintenance replacement and new setup assemblies.

Key Features

• Tapered nose profile with a tapered height of 3/8 inch and tapered width of 5/8 inch for step-bridging workholding
• C-1018 carbon steel construction for consistent strength and machinability
• 1.5 inches of clamping travel accommodates varying workpiece and step block heights
• 3/4-10 tap size fits standard T-slot clamping hardware
• Black finish for corrosion resistance in shop environments
• Compact 6 inch overall length suits confined table setups

Compatibility

Designed as an OEM-style replacement or direct-fit addition for standard T-slot workholding clamping sets used on manual milling machines and drill press tables.

Installation Notes

Installation is performed by machinists or tool-and-die technicians as part of workpiece setup. Power down and lock out the machine before adjusting or repositioning any clamping hardware on the table. Ensure the step block height is matched correctly to the workpiece height so the strap bears load evenly across its length rather than only at the nose. Do not overtighten the stud nut without confirming the strap is properly supported at both ends.
