Sealey 3/8" Drive Hexagon WallDrive Socket Metric

This 18mm socket serves various automotive and machinery applications, including some brake caliper bolts and suspension components. The 3/8" drive size pushes the boundaries of this drive specification, making it ideal for applications where 1/2" drive would be too bulky but adequate torque is still required. Manufactured through cold-forging of Chrome Vanadium steel with subsequent hardening and tempering, this socket delivers professional-grade durability. The WallDrive® socket configuration's innovative approach grips fastener flats rather than corners, providing superior torque transfer whilst minimizing rounding risks. The mirror-polished chrome finish combines aesthetic appeal with practical corrosion resistance, whilst the knurled ring ensures controlled handling.
