This Proto 17-piece, 1/2 in. drive socket set features the Maxi-Drive system, which contacts fasteners away from the corner to allow up to 15% more torque compared to standard sockets — reducing the risk of rounding off fasteners. All sockets are crafted from forged steel with a high-polish chrome finish for durability and corrosion resistance.
The set includes an ergonomically designed ratchet handle with a thumb-operated reverse-switch mechanism for easy direction changes, along with a drive extension bar, flex handle drive, and a blow-molded case for organized storage and portability. Ideal for automotive, MRO, and general mechanical applications.
