Gibraltar 30909G Clamp Strap 3/8 in Stud Carbon Steel

Product Description

The GIBRALTAR 30909G is a carbon steel clamp strap designed to secure workpieces in machining, fabrication, and industrial clamping applications. It features a radius nose profile, a 3/8-16 tap size, and a black finish for corrosion resistance. The strap measures 4 inches in overall length, 1-1/4 inches wide, and 5/8 inches high, with 1 inch of travel. Machinists, tool and die makers, and maintenance technicians install this type of strap clamp as part of workholding setups on mills, drill presses, and fixturing plates.

This clamp strap is suited for use in light to medium-duty workholding setups in machine shops, maintenance facilities, and manufacturing environments. The radius nose allows clamping force to be directed efficiently onto the workpiece surface. The 3/8-16 thread size is a common standard that pairs with widely available T-bolts and studs. Its compact profile makes it appropriate for applications where clearance is limited or multiple clamps are staged in close proximity.

Key Features

• Carbon steel construction for durability in shop environments
• Radius nose profile for efficient clamping force distribution
• 1 inch of travel for flexibility in workholding setups
• 3/8-16 tap size compatible with standard T-bolts and studs
• Black finish for basic corrosion resistance
• Non-serrated contact surface to avoid marring workpiece finishes

Compatibility

Designed as an OEM-style workholding component compatible with standard 3/8-16 T-bolts, studs, and clamping kits used in general machining and fixturing applications.

Installation Notes

Clamp straps of this type are installed by machinists or maintenance technicians as part of manual workholding setups. Ensure the machine is fully powered down and the table is clear before positioning clamps. Use a torque wrench appropriate to the fastener grade when tightening the stud to avoid over-stressing the strap or distorting the workpiece. Step blocks or parallels should support the rear of the strap to maintain a level clamping angle.
