Built with drop-forged, heat-treated S2 alloy steel bits and hardened chrome vanadium steel sockets, this set is aimed at reducing wear while increasing turning power. The sockets feature a fully polished, chrome plated mirror finish, while the bits use a zinc phosphate treatment for rust and corrosion resistance.
For easier day-to-day use, the bit ends are precision chamfered to help them insert smoothly, and sizes are stamped on both the sockets and the heavy-duty storage case for quick identification. The set meets and exceeds ANSI and is backed by LEXIVON’s lifetime limited warranty.
