Description
Applying high torque to large variable fasteners requires an extended lever arm and a strong jaw base. The Magnum 63112 provides 12 inches of leverage to turn heavy plumbing fittings or structural bolts using an adjustable knurled thumb wheel. Forged from high-quality chrome vanadium steel, this wrench includes a metric scale on one side to confirm fastener dimensions during setup.
