How to select the correct PROTO impact socket for your application?

To select the correct PROTO impact socket, match the drive size (3/8") to your impact wrench, choose the socket size (15/16 in) to fit your fastener, and decide between shallow or deep length. The 6-point design reduces rounding on hex fasteners. Always use impact-rated sockets like the J7730H for power tools to avoid breakage.
