Heavy-Duty 12-Inch F-Clamps, 2-Pack, 550 Lbs Forged Alloy Steel | 3 inch Throat F-Style Bar Clamps for Welding, Metalworking & Fabrication, Swivel Pad & Black-Oxide Spindle

Features

• HEAVY-DUTY FORGED ALLOY STEEL Drop-forged alloy steel bar and jaws hold your workpiece steady for welding, cutting, and grinding, rated to a maximum clamping capacity of 550 lbs (245 kg). A heavier gauge than light-duty stamped clamps, built for real fabrication loads.
• 3" THROAT & 12" OPENING The 3 in (80 mm) throat clears the edge of your work for everyday clamping jobs, while the 12 in (300 mm) opening takes thick plate, box tube, and stacked stock with room to spare.
• BLACK-OXIDE THREADED SPINDLE The threaded spindle turns smoothly through repeated open-and-close cycles, finished in black oxide to resist rust and corrosion in a hot, spatter-heavy shop.
• SWIVEL PAD The pad tilts to sit flat against angled or round stock, spreading pressure evenly for full contact across the workpiece surface.
• STEEL RAIL END-STOP The sliding arm slides along the steel rail for fast positioning before the spindle locks it down, and a steel stop fixed to the rail end keeps the arm from sliding off in use.
