Gibraltar 30502G Clamp Strap Steel Tapered Nose 4 in

Product Description

The GIBRALTAR 30502G is a steel clamp strap with a tapered nose profile, designed for workholding and fixturing applications in machining, fabrication, and toolroom environments. The strap measures 4 inches in overall length, 1 inch wide, and 5/8 inch high, with a 1-7/16 inch travel slot. Constructed from 1018 steel with a black finish, it provides durable clamping force across a range of setups. The serrated heel engages the step block or support reliably, and the tapered nose concentrates clamping pressure at the contact point. Machinists, tool and die technicians, and fabricators install this part as part of standard T-slot workholding configurations on milling machines and surface plates.

This clamp strap is suited for conventional T-slot clamping setups on milling machines, drill presses, and surface grinding fixtures in both job shop and production environments. The tapered nose allows precise contact positioning on the workpiece, and the serrated heel prevents slippage during clamping. The 1-7/16 inch slot accommodates a standard T-slot bolt for adjustable positioning along the strap length. This part is sold individually and is appropriate for light to medium workholding duty in manual machining operations.

Key Features

• Tapered nose concentrates clamping load for precise workpiece contact
• Serrated heel resists slipping on step blocks or support pads
• 1018 steel construction provides consistent strength and machinability
• Black finish for corrosion resistance in shop environments
• 1-7/16 inch travel slot allows adjustable bolt positioning
• Compact profile at 4 inches OAL suits tight fixturing setups

Compatibility

Designed as an OEM-style replacement or standard addition to T-slot workholding systems on milling machines, drill presses, and surface plates using standard T-slot clamping hardware.

Installation Notes

Installation is performed by machinists or toolroom technicians using standard T-slot bolts, step blocks, and strap clamp sets. Ensure the milling machine or fixture table is de-energized and the spindle is stopped before adjusting workholding hardware. Position the strap so the tapered nose contacts the workpiece and the serrated heel rests on the step block at the same height or slightly below the workpiece surface to maintain proper clamping angle. Torque the T-slot bolt according to the machine tool manufacturer's workholding guidelines.
