Irwin 18 Locking C-clamp with Swivel Pads 6 Inches

Product Description

The IRWIN 18 is a locking C-clamp with swivel pads, built from alloy steel for use in metal fabrication, welding, woodworking, and general trade applications. The wide-opening jaw design accepts a range of workpiece shapes, while the swivel pads adjust to the angle of the clamping surface to distribute pressure evenly. At 6 inches (150mm) jaw capacity, this clamp handles mid-size fabricating tasks without requiring a secondary fixture. The locking mechanism holds clamping force without continuous hand pressure, freeing the operator to position or tack work. Pipefitters, welders, ironworkers, and maintenance technicians commonly keep this tool on hand for tacking, holding, and positioning work during assembly.

The IRWIN 18 suits residential and commercial fabrication environments where awkward or tapered workpieces need to be held without marring the surface. The swivel pads are especially useful on angled stock, tubing, and finished materials where a fixed pad would rock or concentrate load on a single point. Typical install and use scenarios include structural tacking, sheet metal work, pipe fitting, and light machine assembly. The clamp weighs 0.652 pounds, making it easy to carry on the job without adding bulk to a tool bag.

Key Features

• Alloy steel construction for strength and durability under clamping load
• Swivel pads accommodate tapered, angled, and irregularly shaped workpieces
• 6 inch (150mm) jaw opening handles a wide range of mid-size clamping tasks
• Locking mechanism maintains holding force without continuous hand pressure
• Lightweight at 0.652 pounds for portability on the job site
• Wide-opening jaw design provides versatility across multiple workpiece profiles

Compatibility

Designed as an OEM-style locking C-clamp for general trade and fabrication use across welding, pipefitting, woodworking, and mechanical assembly applications.

Installation Notes

No power source or electrical shutoff is required for use. Adjust the screw mechanism to the approximate jaw gap before applying final clamping force to avoid overloading the swivel pads. Inspect swivel pad condition before each use to confirm they seat flush against the workpiece surface. Follow applicable shop safety practices and relevant OSHA hand tool guidelines when clamping under load.
