Description

The Sealey S1221D 21mm deep socket with 1/2" drive is another extremely common size for wheel nut applications, particularly on European vehicles and many commercial vehicles. This 21mm variant is the standard fitment for numerous car manufacturers, making it essential for tyre shops, mobile mechanics, and vehicle owners who perform their own wheel changes and maintenance. Cold-forged from premium Chrome Vanadium steel, this socket delivers the strength and durability necessary for frequent wheel changing operations and high-torque applications. The deep hexagon profile accommodates recessed wheel nuts common on modern alloy wheels, whilst the WallDrive® configuration provides maximum contact with the fastener, reducing the risk of rounding expensive wheel nuts and protecting wheel finishes. The half chrome, half satin finish offers excellent resistance to road salt, brake dust, and environmental corrosion, ensuring reliable performance season after season. The knurled ring enhances grip security during roadside wheel changes or when working with oily hands in workshop conditions. Hardened and tempered for enhanced strength, this 21mm socket withstands repeated high-torque applications without compromising performance or accuracy. A must-have tool for any comprehensive automotive toolkit. Backed by Sealey's comprehensive lifetime guarantee.
