Premium S2 steel bits not only have the length to reach, they have the strength to free stubborn screws.
Bit ends are precisely milled for an exact fit in fastener head, eliminating extra play that could cause damage.
Notched-end sockets lock onto any 3/8 in. drive ratchet, preventing them from being dropped or stuck in fastener.
If a bit becomes damaged or broken, simply loosening the retaining screw allows it to be removed and repaired or replaced.
