How to select the right PROTO socket set for metric fasteners?

To select the right PROTO socket set, match the drive size (e.g., 3/8 in) to your ratchet, and ensure the socket range covers your fastener sizes. For deeper bolts, choose deep sockets like those in the J52209 set. Tether-ready options are recommended for overhead work. Always verify the point configuration (12-point vs. 6-point) for your application.
