The 21mm socket serves specialist applications in automotive and machinery work where this less common metric size is specified. This 3/8" drive variant pushes the capabilities of this drive size, making it ideal for situations where accessibility is paramount but adequate torque is still required. Cold-forged from Chrome Vanadium steel and heat-treated for enhanced strength, this socket handles demanding fastening tasks. The innovative WallDrive® configuration grips fasteners on their flats, delivering superior torque whilst significantly reducing the risk of corner rounding. The mirror-polished chrome finish combines visual appeal with practical corrosion resistance, whilst the knurled ring provides essential grip security.
