GearWrench 80551 57-Piece 3/8" Drive 90-Tooth SAE and Metric Tool Set

The GearWrench 80551 57-piece 3/8-inch drive SAE and metric socket and ratchet set fastens, loosens, and services automotive, industrial, and mechanical assemblies utilizing a high-performance 90-tooth teardrop ratchet delivering a tight 4-degree swing arc. Forged from premium alloy steel with a full polish chrome finish that resists rust and corrosion, this comprehensive tool kit includes both standard and deep 12-point sockets designed with off-corner loading geometry to prevent fastener rounding. Outfitted with knurled chrome extensions, stubby and standard ratchets for enhanced clearance in cramped engine bays, hard-stamped size markings with tactile SAE and metric differentiation lines, and a heavy-duty blow-molded storage case, it equips professional technicians and trade specialists with exceptional workspace access and reliable fastening torque.
