Perfect for the needs of both pros and serious home mechanics, this mirror-polished 33 piece SAE and metric Chrome Vvanadium socket set is strong as well as beautiful. The jumbo high-visibility size markings are forged right into each socket sidewall and will never fade or wear off. Also features our innovative Z-Drive design which helps these sockets get a better grip on fasteners giving more control and reducing slippage. Precision chamfered openings make it easier to slide the sockets over fasteners. Punched center holes add working space for taller nut and bolt stock.
