1/2 Inch Drive Deep 6-Point Impact Socket Set with Rails and Tray, 31-Piece (8-3

Full-Length Socket Well - Not only is the socket a deep length, but the interior well also extends far into the socket, which allows for better fastener engagement in more situations. Fully Stepped Shoulders - The narrowed socket diameter goes all the way down to the base of the socket on small deep-length sizes. This allows for better reach into tight, recessed areas. Prevents Fastener Round-Off - Radiused corners prevent fastener round-off by applying force to a fastener's flat sides, rather than its corners.
