If you've ever grabbed a 13mm socket only to find it too tight, but a 14mm is too looseand you know it's not SAEyou've experienced how vehicle bolts deviate from factory perfection over time. This specialized set includes Cro-Mo impact grade sockets in 0.5mm increments allowing you to use the 0.5mm under sockets for securely fitting rounded or damaged fasteners, and the 0.5mm over sockets for tackling swollen, corroded, or cap-covered nuts. You can tap under-sized sockets into place with a hammer for maximum grip on difficult jobs, guaranteeing a solution for nearly every imperfect metric and often even SAE fasteners too.
