Wilton 402 C-Clamp 3500 lb tool storage

Wilton 402 C-Clamp Overview

The Wilton 402 is a regular-duty C-clamp built for metalworking, welding and general fabrication tasks. Its forged steel body and 3500 lb clamping force suit professional shops and serious hobbyists who need reliable holding power for steel plate, angle iron or heavy timber assemblies. The V-grooved jaw with included swivel pad grips round, angled or flat workpieces without marring the surface. This clamp is not for buyers who need deep-throat reach beyond 2 1/4 in or a quick-release mechanism for rapid repositioning.

Thermals Noise and Power

As a purely mechanical hand tool the Wilton 402 generates no heat, draws no electricity and produces no audible noise during operation. The black-oxide spindle and sliding T-handle transmit torque smoothly so the operator feels consistent resistance without vibration or chatter. Powder-coated gray finish resists corrosion and weld spatter, keeping threads clean for repeatable clamping cycles. No external power source, coolant or compressed air is required to maintain performance.

Build Integration and Clearance

The clamp occupies a compact footprint with 2 1/4 in jaw opening and matching throat depth, fitting between structural members, inside jigs or on crowded benchtops. Forged steel construction withstands hammer taps for stubborn fits while the single anvil and spindle keep the mechanism simple to clean and lubricate. The sliding T-handle provides leverage in tight quarters where a standard cross-pin handle would bind. Users needing multiple simultaneous clamps or wider opening capacity must add additional units.
