The CTA 10mm Socket Set, No. 3805, features five popular style 10mm sockets in 1/4" and 3/8" drives. The included designs are stubby, standard, deep, flex, and magnetic impact sockets. The magnetic impact sockets are manufactured using chrome molybdenum for durability and are also coated with manganese phosphate to better withstand corrosion. All other sockets have a polished chrome finish and a knurled non-slip ring for maximum grip when in hand (except on the two U-joint sockets). All 10mm sockets come packed on a socket rail for an organized and easy storage solution.
