8-6540 - Wilton 4800S-48C Spark-Duty 48-Inch Copper Spindle F-Clamp

Heavy-Duty Clamping for Large Scale Fabrication

When your projects involve heavy steel and high-amperage welding, you need a clamp that won't back down. The Wilton 4800S-48C, also known by stock number 86540, is a 48-inch Heavy Duty F-Clamp designed to meet the rigorous demands of the modern fabrication shop. With a massive 48-inch clamping capacity, this tool is perfectly suited for large jigs, fixtures, and structural assemblies where reach and rigidity are paramount. It represents the gold standard in the 4800S Spark-Duty series, combining traditional durability with modern innovation.

The defining characteristic of this model is its Spark-Duty copper-plated spindle. Welding spatter is the enemy of threaded tools, but the copper coating on this spindle prevents spatter from bonding, significantly extending the service life of the clamp. This means less time spent cleaning threads with a wire brush and more time fabricating. The frame itself is constructed from drop-forged steel, offering exceptional rigidity. This ensures that when you apply pressure, the force goes into holding your workpiece together, not bending the clamp arm, providing a safe and secure setup for tacking and welding.

Versatility is built right in with Wilton's Quick-Twist pad technology. Every 4800S-48C comes with a V-Groove pad included in the box, allowing you to instantly adapt the clamp for holding pipes, tubes, and other round materials without slipping. The ergonomic Wilton-Grip handle is designed with anti-fatigue properties, ensuring comfort during repetitive clamping tasks. Whether you are fitting up structural columns or assembling complex machinery, the Wilton 4800S-48C delivers the reliability, strength, and smart features required for professional results in any industrial setting.
