The Nepros Socket, No. NB2-10W, offers a compact design that allows it to access bolts in tight spaces and a high-precision cold forging that results in tolerances approaching zero, according to the company. The NB2-10W socket design helps disperse stress, making it more difficult to damage the bolt or nut edges, and ensuring sure transfer of force for tightening or loosening. With the stress spread out along a surface, the wall thickness that was necessary for line-type contact can be reduced.
