NIETZ WELDER’S CLAMP LOCKING PLIER (CRAB JAW) W TYPE 543 15 910 (10" - 54315910)

Type: A welder's clamp locking plier, also known as a crab jaw locking plier or a clamp. This is a specialized tool designed to securely hold and position workpieces for welding, fabrication, and other metalworking tasks.

Dimensions: The product code "543-15-910" is highly suggestive of a 10-inch (250mm) tool, as the final three digits often represent the size. The 10-inch length provides significant leverage.

Jaws: The most defining feature of this tool is its "crab jaw" design, also referred to as a "W-type" or "swivel jaw" design. The jaws are wide and have a pivoting or swivel mechanism. This allows the tool to securely grip irregularly shaped objects or to clamp two pieces of metal together at different angles. This is particularly useful for holding pipes or odd-shaped parts for welding.

Material: Like other high-quality NIETZ tools, this would be made from high-quality Chrome Vanadium (Cr-V) steel. This material is drop-forged and heat-treated to ensure maximum strength, durability, and resistance to wear and tear from high temperatures and welding spatter.

Design Features:

Locking Mechanism: The primary feature is the ability to adjust the jaw opening and then lock it in place, providing a powerful, constant grip that allows for hands-free operation.

Adjustment Screw: A screw at the end of the handle is used to precisely adjust the jaw opening and the clamping pressure.

Release Lever: The pliers are released by a lever at the base of the handle.

Application: These pliers are an essential tool for professionals in metalworking, welding, and fabrication for:

Holding and clamping parts in alignment for tack welding.

Securing two pieces of metal together before they are permanently joined.

Clamping workpieces to a table.

Manipulating and holding pipes or other round stock.

Origin: NIETZ tools are typically Made in Taiwan, a region with a strong reputation for producing high-quality hand tools.
