Product Number: SP1221
Variations
When working on wheel nuts, suspension components, or other high-torque fasteners, a socket that rounds off under pressure is not just an inconvenience it can bring a job to a complete halt. The Sealey SP1221 is a 21mm standard-depth socket with a 1/2" square drive, drawn from the Premier Hand Tools range and designed for daily professional use. Cold-forged from Chrome Vanadium steel and hardened and tempered for added strength, it is built to withstand the demands of heavy-duty workshop use. The WallDrive® socket configuration contacts the flat faces of the fastener rather than the corners, reducing the likelihood of rounding under high torque a critical feature when dealing with wheel nuts and other heavily loaded fixings commonly encountered in automotive and HGV work. The chrome-plated, fully polished finish gives corrosion resistance and keeps the socket looking professional in daily use. A knurled ring ensures a secure, confident grip even with oily or gloved hands. Backed by a lifetime guarantee, the SP1221 is a dependable, long-lasting socket for professionals who cannot afford downtime.
