STANLEY 66‑166‑A 100+ SLOTTED SCREWDRIVER – 5/16 IN x 6 IN

Purpose‑built for industrial duty, the Stanley 66‑166‑A 100+ Slotted Screwdriver combines high‑torque performance with job‑site durability. A fluted, full‑size acetate handle withstands heavy use and resists chemicals, while the alloy‑steel round shank is fully ground, polished, and chrome‑plated for long‑term corrosion resistance. The 5/16 in keystone slotted tip is precision‑formed for a secure, repeatable fit in fasteners, helping reduce cam‑out and improving control during installation and removal. The 6 in shank length provides practical reach without sacrificing leverage, making this a reliable go‑to for electricians, mechanics, MRO teams, and general contractors.
