Wright Tool 3-1/2" Drive 6 Point Standard Impact Socket - 7-7/8"

This 7-7/8" socket is built for 3-1/2" drive impact work, the kind of heavy equipment and industrial applications where standard sockets just won't cut it. Wright Tool made this one a 6 point standard socket, so you get maximum contact on the flats of the fastener instead of the corners. That matters when you're breaking loose big lug nuts, heavy machinery bolts, or fasteners on mining and construction equipment that have been torqued down hard and sat outside for years. This socket is forged and machined, then precision heat-treated for the right balance of hardness and toughness so it can take repeated impact without cracking or rounding out. The patented Wright Drive design spreads the load over a bigger surface area on the fastener, which means better grip and less chance of stripping the head. It's finished in oiled black oxide to fight off rust and corrosion in rough job site conditions, and the size is stamped clear and deep so you can read it fast even with grease and grime on your hands. Every one of these is designed, engineered, and made in the USA at the Barberton, Ohio plant, and it meets ASME B107 standards for hand tools. Heavy equipment mechanics, riggers, and crews working on industrial machinery, ships, or large scale construction gear are the ones reaching for a socket this size. It's not for the truck box, it's for the guy running an impact wrench big enough to need 3-1/2" drive.
