Gibraltar 30953G Clamp Strap 21/32 in Stud Tapered Nose

Product Description

The GIBRALTAR 30953G is a carbon steel clamp strap designed for secure workholding in machining and fixturing applications. It features a tapered nose profile and accepts a 21/32 inch stud with a 5/8-11 tap size. The strap provides 1/2 inch of travel, allowing for adjustment across a range of part heights. At 4 inches overall length and 5/8 inch high, this compact strap is well suited for setups where clearance is limited. Material grade is C-1018 carbon steel with a black finish for corrosion resistance. Machinists, toolmakers, and fixture builders are the primary installers of this component.

This clamp strap is used in manual and CNC machining environments for holding workpieces on mill tables, surface plates, and fixtures. The tapered nose allows the strap to bridge stepped surfaces or reach into recessed clamping areas. At 1-1/4 inches wide and 1/4 inch tapered height, it fits in tight fixture setups where standard straps may not seat properly. The 1-3/16 inch end-to-stud center and 1/2 inch end-to-hole center dimensions allow for precise positioning in T-slot and stud-based clamping configurations.

Key Features

• Tapered nose design for bridging stepped or recessed clamping surfaces
• C-1018 carbon steel construction for strength and durability
• 21/32 inch stud size with 5/8-11 tap compatibility
• 1/2 inch travel for height adjustment across varying workpiece thicknesses
• Black finish for surface protection
• Compact 4 inch overall length for use in tight fixture setups

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard T-slot and stud-based workholding setups using 5/8-11 threaded studs.

Installation Notes

Installation is performed by machinists or toolmakers during fixture setup. Before adjusting or removing clamp straps under load, ensure the machine is powered down and any stored mechanical energy is released. Use the correct stud length to achieve full thread engagement at the specified tap size. Do not over-torque the stud nut beyond the clamp's rated capacity, as this may deform the strap or damage the workpiece surface.
