• CORTOOL impact socket set 1/2 drive, 20-Piece 1/2" impact sockets are made of high-quality forged heat-treated chrome vanadium steel, with a black phosphoric acid coating on each socket surface to resist corrosion and prevent oil and rust stains. Each impact socket has a clear laser size mark, which allows you to select the right socket quickly and easily even in low light conditions. The 6-point socket design enlarges the contact area between the socket and the fastener, enhancing the locking force, reducing wear and preventing the corners from rounding off.
