CMMT87220 Ratcheting Box Wrench Set, Metric & SAE, 12-Point, 20-Piece

The Craftsman CMMT87220 20-Piece Ratcheting Box Wrench Set combines metric and SAE sizes in one comprehensive collection, designed for automotive work, plumbing, maintenance, and general fastening tasks. Each wrench features a 12-point box end and an integrated 90-tooth ratcheting mechanism that lets you tighten or loosen bolts without removing the wrench—ideal for working in confined spaces where repositioning is difficult or impossible.

Built from forged steel with a polished chrome finish, these wrenches resist corrosion and deliver professional durability for both casual DIYers and working professionals. Large, legible size markings make it easy to spot the wrench you need, while the organized boxed layout keeps all 20 pieces portable and ready to grab. The 12-point design ensures a secure grip on fasteners, reducing the risk of rounding corners and improving torque transfer.
