About this item
  • 【6-POINT DESIGN】The 6-sided design allows the socket to fit tightly against the six sides of the nut, avoiding local stress concentration and reducing the risk of slipping. It can provide more reliable operational stability during aerial work. It can also protect the integrity of the bolt and reduce replacement costs.
  • 【HIGH QUALITY IMPACT SOCKET】Mr.wintek 1/2 drive 21mm impact socket is designed for erecting scaffolding outdoors or at height. It can securely tighten the nuts on the scaffolding clamps and also ensure that the socket will not fall off when the scaffolding is dismantled.
  • 【55MM INNER DEPTH】 81.5mm full length + 55mm inner depth is designed for scaffolding applications that require extended reach, such as deeply recessed nuts in larger couplers, long bolts, or adjustment spindles on base jacks. The extra depth ensures full engagement when fasteners sit deeper than typical sockets (e.g., 35mm inner depth) can reach.
  • 【CR-MO MATERIAL】Mr.wintek 21mm socket is made of cr-mo material, which has excellent hardness and wear resistance. It can better withstand impact and is not easy to break even when the nuts on the scaffolding clamps need to be frequently disassembled and assembled. The surface of the socket has a black phosphating coating, which can further resist corrosion and is suitable for long-term outdoor use.
  • 【RETAINING PIN AND O-RING】The retaining pin and O-ring are made of high-quality materials and are not easy to damage. The two work together to lock the socket and the impact wrench to prevent the socket from loosening due to vibration or tilting during operation, thereby causing safety hazards. The fixed structure can also reduce the slippage between the socket and the impact wrench, so that it does not slip during high torque operations.
  • 【TWO SIZE MARKINGS】Mr.wintek socket surface is simultaneously laser-etched and embossed to allow for quick identification even when the surface is worn or in dim environments, further improving operational efficiency.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
