Sealey 1/2" Drive Double Ended Socket for Swollen Wheel Nuts

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.

Features and Benefits:
• 21mm and 21.5mm ends provide precise fitment for swollen nuts in this common size range
• Tempered and anodised Chrome Molybdenum for corrosion resistance and durability
• Thin walls for use with impact tools in confined spaces
• Double-ended 6-point design for versatile application
• External sleeve prevents damage to alloy wheels and nuts
• 1/2" drive for compatibility with standard drive tools
