Stride Tool introduces the Rotowrench 8-in-1 Prostyle Box Wrench, featuring the eight most common wrench sizes in one slim-profile tool. SAE/Imperial model 10S fits nuts and bolts from 5/16″ to 3/4″, and Metric model 10SM fits sizes from 8mm to 19mm. Manufactured of hardened chrome moly steel, each Roto-Wrench box end socket has twelve gripping teeth that will not round the corners of nuts and bolts. Its slim profile line and 30-degree swing arc make it easy to use in tight spaces, and the design allows the user to change wrench sizes in seconds. Contact: Stride Tool, 530 E.
