Gibraltar 30407G Clamp Strap 5/8 Inch Stud Tapered Nose

Product Description

The GIBRALTAR 30407G is a steel clamp strap designed for workholding and fixturing applications in machine shops and fabrication environments. It features a tapered nose profile and plain heel, providing a straightforward clamping geometry suited for securing workpieces to T-slot tables, milling machine beds, and similar fixtures. The strap measures 2.5 inches in overall length, 1.25 inches wide, and 0.625 inches high, with a 9/16 inch travel range. Manufactured from 1018 steel with a black finish, it delivers reliable strength and corrosion resistance for repeated use in production settings. Machinists and tooling technicians are the primary installers of this component.

This clamp strap is used in standard workholding setups on milling machines, drill presses, and surface grinders where a 5/8 inch stud is required. The tapered nose allows the strap to wedge against a step block or riser, converting stud tension into consistent downward clamping force on the workpiece. It is appropriate for both one-off setups and repetitive production fixturing. The non-serrated, non-tapped design keeps setup time minimal and suits applications where the strap is repositioned frequently.

Key Features

• Tapered nose profile for positive contact against step blocks and riser sets
• Plain heel design for clean seating on flat fixture surfaces
• 1018 steel construction provides good machinability and tensile strength
• 9/16 inch travel accommodates a range of workpiece heights
• Black finish for surface protection during storage and use
• Non-serrated, non-tapped body simplifies repositioning during setup

Compatibility

Designed for use with 5/8 inch studs in standard T-slot workholding setups on milling machines, drill presses, and similar machine tool fixtures.

Installation Notes

Installation is performed by machinists or tooling technicians as part of a workholding setup. Ensure the machine table and T-slot hardware are clean and free of chips before positioning the strap. The stud, strap, step block, and T-nut should be aligned so that the clamp applies force as close to the workpiece as practical to minimize deflection. Always power down and lock out the machine before making any adjustments to fixturing components.
