The WILTON 20301 is a 400 Series C-clamp designed for secure workholding in fabrication, welding, and general mechanical assembly. It provides a jaw opening range of 0 to 2 inches and a throat depth of 2 inches, making it well suited for clamping stock, fixtures, and assemblies where a compact, rigid clamp is required. The cast construction and threaded screw mechanism deliver consistent clamping pressure across a range of materials. Tradespeople and shop technicians reach for this clamp when they need a reliable, no-frills hold on smaller workpieces during layout, tack welding, or light machining operations.
This clamp is appropriate for use in professional trade shops, fabrication facilities, and field service environments where controlled clamping force on smaller components is needed. The 2-inch jaw capacity suits thin plate, angle iron, conduit, and similar stock. It is commonly used by welders, pipefitters, ironworkers, and maintenance technicians who require a dependable clamp for everyday holding tasks.
Designed as an OEM-style C-clamp replacement or addition within the WILTON 400 Series clamp lineup, suitable for general fabrication and mechanical assembly applications requiring up to 2 inches of jaw capacity.
C-clamps of this type are installed by hand; no power tools are required for standard use. Always inspect the screw and swivel pad for wear before applying clamping force to critical assemblies. Do not use a cheater bar or extension on the handle to exceed the designed clamping force, as this can damage the clamp or workpiece. When used in welding applications, ensure the clamp is rated for heat exposure in the work zone.
