Gibraltar 30405G Clamp Strap Steel 1/2 in Stud Tapered Nose

Product Description

The GIBRALTAR 30405G is a steel clamp strap designed for workholding and fixturing applications in machining, fabrication, and toolroom environments. Built from 1018 steel with a black finish, this strap accepts a 1/2 inch stud and features a tapered nose with a plain heel. It measures 4 inches overall length, 1-1/4 inches wide, and 3/4 inches high, with a travel of 1-5/16 inches. The slot length is 1.313 inches, and the centerline of the slot to the nose measures 1-5/32 inches. Machinists, toolmakers, and fabricators use this style of clamp strap to secure workpieces on milling machines, drill presses, and fixture plates.

This clamp strap is suited for standard milling and drilling setups where a tapered nose profile is needed to apply clamping force close to the workpiece. The 1018 steel construction provides reliable strength for general-purpose fixturing. The black finish offers a degree of surface protection during storage and use. The non-serrated, non-tapped design keeps the strap straightforward for typical T-slot table and fixture plate applications. It is sold individually and is a common component in shop-built clamping setups.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with T-slot fixturing and clamping setups. Ensure the machine spindle is powered down and the table is stationary before adjusting or repositioning clamp straps. Use a properly sized stud, nut, and step block combination to achieve level clamping and avoid rocking the strap. Do not overtighten the stud nut beyond the rated capacity of the stud hardware being used.
