Not what I expectedFor everyday automotive use this socket did not meet my expectation. I would definitely recommend going with Snap on’s flank drive impact socket instead. Matco’s socket has a thicker wall which may last longer but will damage rims due to low clearance and the socket does get stuck on swollen lug nuts and results in having to beat out the lug nut. Price wise would go with a husky impact socket over matco’s and would recommend snap on for every day automotive use.
