Hex Bit Socket

IET Allen Key Sockets are designed to use with Hydraulic, Pneumatic or electric Tools.
They are made manufactures by slotting and broaching for good grip on nut to avoid hex breakage.
Length of hex are not long in order to avoid bending.
All Allen Key sockets are made from high strength alloy steel.
These are heat treated for the best strength and impact resistance.
Sockets are made from 1/4" to 1.1/2" Square Drive.
