This 29-piece bolt extractor set is designed to handle a wide range of nut and bolt removal tasks, with sizes from 6mm to 3/4" suitable for automotive repairs, machinery maintenance, and home improvement projects. The set includes adapters and sockets compatible with 3/8" and 1/4" manual or power tools such as ratchets and electric wrenches, allowing convenient use with tools you already own. Constructed from high-strength Cr-Mo steel, the extractors provide excellent durability, break resistance, and corrosion protection thanks to a sandblasted finish. The reverse spiral design grips stripped or damaged bolts securely, while the hexagonal top prevents slipping for efficient removal. A waterproof Pp storage case keeps all tools neatly organized, easy to transport, and well protected from rust or damage.
