The Master Mechanic 11R Clamping Welding Pliers are 11-inch heavy-duty locking pliers designed for clamping metal parts during welding, grinding, or fabrication tasks. Built in the USA with durable alloy steel, this model is equipped with wide swivel pads to evenly distribute clamping force, making it ideal for working with flat or irregular surfaces without damaging the workpiece. The locking C-clamp design allows for firm, stable holding during high-heat or high-pressure applications, and the screw adjustment tail lets you dial in clamping pressure based on material thickness or clamping strength needs.
This unit is comparable to professional-grade tools like the IRWIN® VISE-GRIP® 11R and is often favored in automotive, HVAC, metal fabrication, and general industrial maintenance tasks.
