5‑Piece Screw Extractor Set, M3–M18 Range, Left‑Hand Spiral, Storage Box

This 5‑piece screw extractor set removes damaged or snapped fasteners across common metric sizes and includes clearly stepped sizes for quick selection. The slow/left‑hand spiral flute profile grips tighter as counter‑clockwise torque is applied, helping back out stuck screws and bolts without damaging the parent thread. Supplied in a durable plastic storage box to keep each extractor organized for field or workshop use.
