Gibraltar 30408G Clamp Strap Steel 5/8 in Stud Tapered Nose

Product Description

The GIBRALTAR 30408G is a steel clamp strap designed for workholding and fixturing applications in machining, fabrication, and industrial maintenance environments. Built from 1018 steel with a black finish, this strap accepts a 5/8-inch stud and features a tapered nose profile for positive part engagement. It measures 4 inches in overall length, 1-1/2 inches wide, and 3/4 inches high, with 1-3/16 inches of travel to accommodate varying workpiece thicknesses. Machinists, tool and die technicians, and maintenance mechanics install this type of strap as part of a step-block and stud clamping system on mill tables and fixture plates.

This clamp strap is suited for light-to-medium-duty workholding setups on manual mills, CNC machining centers, and surface grinders. The tapered nose directs clamping force downward onto the workpiece when paired with a step block and T-nut or stud assembly. The plain heel style and non-serrated, non-tapped body keep the setup straightforward. It is commonly used in job shops, maintenance facilities, and production environments where repeatable part clamping is required.

Key Features

• Tapered nose directs clamping force onto the workpiece for secure fixturing
• Accepts a 5/8-inch stud for standard T-slot clamping systems
• 1-3/16 inches of travel accommodates varying workpiece heights
• 1018 steel construction provides reliable strength for general workholding
• Black finish for corrosion resistance in shop environments
• Non-serrated, non-tapped body simplifies setup and cleanup

Compatibility

Designed for use with standard 5/8-inch stud T-slot clamping systems commonly found on mill tables and machining fixture plates.

Installation Notes

Installation is typically performed by machinists or maintenance mechanics as part of a manual or CNC mill setup. Always ensure the machine is powered down and the spindle is at a full stop before adjusting workholding components. Use the appropriate T-nuts, step blocks, and studs matched to the table slot dimensions. Do not overtighten the stud nut beyond what is needed to secure the workpiece, as excessive force can deflect the strap or damage the workpiece surface.
