Faithfull 3/8" Drive Hexagon Socket Metric 3/8" 21mm

About this tool

The Faithfull 21mm 3/8" Drive Hexagon Socket represents one of the larger sizes in this range, specifically designed for substantial fasteners found in heavy-duty automotive applications, agricultural machinery, and industrial equipment. This 21mm socket is particularly useful for larger suspension components, differential work, and heavy chassis fasteners. Forged from premium chrome vanadium steel, this socket is engineered to handle higher torque loads whilst maintaining dimensional accuracy. The hardening and tempering process ensures the socket retains its strength even under sustained professional use, whilst the satin chrome plated finish guards against corrosion in demanding workshop environments. The precision hexagon design creates secure contact across all fastener faces, preventing rounding and allowing confident application of the higher torque often required for larger fasteners. The chamfered end design facilitates easy nut location and entry, particularly beneficial when dealing with longer studs or recessed applications.
