GEARWRENCH 85798 8PC 72T 12Pt XL Locking Flex Head Ratcheting Combination SAE Wrench Set

The GEARWRENCH 8-Piece SAE XL Flex Head Ratcheting Combination Wrench Set is engineered for serious professionals who need speed, access, and reliability in tight spots. Each wrench in the set features a 72-tooth ratcheting box end that turns fasteners with as little as 5° of swing, making it ideal for confined spaces where traditional 30° swing wrenches just won’t cut it. Manufactured from strong alloy steel and finished in a high-polish chrome, these wrenches are built to last and resist corrosion. The long beam design provides better reach, and the flexible locking head allows access to hard-to-reach bolts and angles, making it a solid choice for tradespeople working in engine bays, equipment maintenance, and field repair.

This 8-piece SAE set includes sizes from 5/16″ to 3/4″, each offering the patented GearWrench ratcheting mechanism with off-corner loading to improve grip and minimize fastener rounding. Whether you’re working on a construction site, maintaining machinery in a municipal fleet, or repairing HVAC systems, this set keeps your workflow moving with fewer tool changes and better accessibility.
