Faithfull 1/2" Drive Hexagon Socket Metric

The FAISOC1221 is a 21mm hexagon socket with 1/2" square drive, ideal for larger fasteners commonly encountered in automotive, agricultural and heavy machinery applications. This size is particularly useful for wheel nut applications and larger structural bolts where substantial torque is required.

Forged from professional-grade chrome vanadium steel, this socket undergoes hardening and tempering processes to ensure exceptional strength and resistance to wear, even under demanding working conditions. The satin chrome plated finish provides excellent corrosion protection, maintaining performance and appearance over extended service life.

The precision hexagon design ensures an accurate and secure fit on both nuts and bolts, reducing the risk of rounding or slippage during torque application. A chamfered end allows for quick nut location and entry, improving efficiency when working with multiple fasteners. The 1/2 inch square drive offers the optimal balance of strength and versatility, making it the most popular drive size throughout the UK and Ireland.
