About this product
The Sealey SX1821S features socket sizes of 21mm and 21.5mm, perfectly suited to the mid-range wheel nut sizes commonly found across a wide variety of passenger cars, vans, and light commercial vehicles where swelling has rendered standard sockets ineffective. When a nut swells beyond its standard 21mm dimension, engagement becomes unreliable and risks rounding — this socket's half-size increment ensures a firm, precise fit for controlled, damage-free removal. Built from tempered and anodised Chrome Molybdenum, it combines toughness with excellent corrosion resistance for reliable long-term performance. Slim socket walls allow use with impact tools even in restricted spaces, and the double-ended 6-point configuration with external sleeve keeps alloy wheels and nut faces protected throughout the job.
