16-Inch Heavy-Duty F-Clamps — Forged Alloy Steel, 2-Pack

Product review

Included: a pair of 16-inch F-style clamps sold as a 2-pack for workshop and fabrication use.

Construction: both the bar and jaws are made from drop-forged alloy steel for heavy-duty service. The clamps are built heavier than stamped light-duty types, intended for sustained fabrication workloads and resisting deformation under load.

Capacity and size: each clamp is rated to a maximum clamping force of 3,450 lbs (1,570 kg). The throat depth is 4-3/4 in (120 mm), allowing clamping closer to the center of a workpiece, and the overall opening span is 16 in (400 mm) to accept thick plate, box tubing or stacked stock.

Hardware and finish: the spindle is threaded for smooth tightening and finished in black oxide to help resist rust and shop spatter. Jaws are fixed, flat steel to provide direct, full-width contact with plate, bar and square stock for welding and heavy fabrication.

Rail and sliding arm: the movable arm rides on a steel rail so you can position the clamp quickly before locking the spindle. A steel end-stop is fixed to the rail to prevent the sliding arm from coming off during use.

VerdictThese forged-alloy 16" F-clamps deliver solid, repeatable holding power for shop fabrication. With a 3,450 lb rating, deep 4-3/4" throat and full-width steel jaws they reach and secure thick plate, box tube and stacked stock. The black-oxide spindle and rail end-stop make setup reliable in harsh welding environments.
