This robust wrench simplifies your toolkit by offering a versatile 2-3/4" to 4-3/4" (70 mm to 120 mm) nut and bolt capacity, effectively replacing numerous oversized spanners. Engineered for demanding, high-torque applications, it ensures reliable performance in challenging work environments.

Key Features

• Wide Jaw Capacity: The OTC 7641 adjusts from 2-3/4" to 4-3/4" (70 mm to 120 mm) in 1/8" increments, accommodating common large sizes found on heavy truck axle nuts, hydraulic fittings, and industrial hardware.
• High Leverage Design: With an overall length of 35.5" (90.2 cm) and a weight of 31.6 lb (14.3 kg), this wrench delivers substantial leverage for loosening corroded or over-tightened fasteners, rated to withstand up to 5,000 ft-lbs of torque.
