21MM 1/2" Impact Scaffold Socket With Ring & Pin

The Blue Spot 21mm 1/2" Impact scaffold socket is manufactured from chrome molybdenum for increased durability, with a blackened phosphate coating which protects against corrosion. 52mm deep and lighter than a regular deep socket, it is the most common socket used by scaffolders. The socket has a safety pin and ring which keeps the socket secure and in place on the impact driver, making it the ideal socket to be used at heights.
