Deep impact socket set in 1/2" square drive, with 14 single hex (6pt) sockets from 10mm to 30mm. The generous 80mm depth gives much better access to hard-to-reach bolts that cannot be adjusted with a conventional set. This heavy duty set is manufactured from chrome molybdenum for strength and durability with a black phosphate finish for improved corrosion resistance. Find the right socket at a glance with the high contrast, easy to read size markings etched onto each socket. Presented in a fitted EVA foam tray for safe and organised tool storage, ideal for tool chest drawers.
