This 21mm non-sparking socket offers reliable performance for substantial fasteners in hazardous environments. Crafted from beryllium copper, this 1/2" drive socket eliminates spark risks whilst maintaining the strength and durability required for demanding industrial applications in potentially explosive atmospheres. The die-forged manufacturing process ensures superior robustness, whilst Sealey's WallDrive® 12-point design grips fasteners on their flat sides, distributing forces evenly to minimize rounding and extend the life of both socket and fastener.
