Precision machining, made of heat-treated steel, with corrosion-resistant black phosphate surface.   The 360-degree omni-directional motion enables the U-joint rotary socket to rotate completely, reaching a narrow space and approaching the fasteners that are difficult to reach.   High contrast size marks are permanently laser, which can be easily read even in low light conditions.   A ball with a spring at the end of the rod locks the socket in place to ensure safety and prevent it from falling.      Packaging includes:   1 x 1/2 inch universal joint rotary socket adapter   1 x 3/8 inch universal joint rotary socket adapter   1 x 1 /4 inch universal joint rotary sleeve adapter   Colour:black   Material:steel      Package Contents:   3 x Wrench socket attachment
