Crescent® 15" Adjustable Wrench with 1/2" capacity has a tension spring that stabilizes the jaw and knurl adjusts easily. The wrench is made of alloy steel and heat treated for durability. It has proportioned dimensions for greatest strength and minimum weight. The chrome plated finish resists rust and corrosion and is polished for a smooth finish. Crescent® Adjustable Cushion Grip Wrenches feature a durable, comfortable, molded rubber cushion on the wide handle. A large knurl allows for easy adjustment and a tight-fitting hex jaw design reduces slippage and tightly grips the fastener for solid, secure operation. The corrosion-resistant chrome finish helps prevent rust.
