The Apex AN-10MM is a socket head (Allen) power bit in 10mm with a 7/16-inch hex drive. The larger 7/16-inch hex drive supports higher torque than 1/4-inch drive bits, while the 10mm metric tip drives large metric socket head cap screws during heavy equipment, fabrication, and machine-tool assembly. Supplied individually for industrial, contractor, and MRO power tool accessory programs.
