US PRO 7634 25pc Screw Extractor Set (Left-Hand Spiral, CR-MO)

The US PRO 7634 25 Piece Screw Extractor Set is engineered to tackle one of the most frustrating workshop problems—damaged or seized fasteners. Designed for professional mechanics, technicians, and serious DIY users, this versatile set provides reliable extraction across a wide range of bolt, screw, and stud sizes.

Each extractor features a left-hand tapered spiral design that bites aggressively into the damaged fixing as torque is applied. This reverse-thread action increases grip the harder it works, helping to loosen stubborn fasteners without slipping. The short extractor length improves access in confined areas such as engine bays, chassis rails, and machinery housings.

Manufactured from hardened chrome molybdenum (CR-MO) steel, the extractors offer excellent resistance to torsional stress and wear. The set covers sizes from 1/8" to 7/8" in precise 1/32" increments, making it suitable for a wide range of automotive, industrial, and maintenance tasks.

The extractors can be driven using a hand ratchet with socket, spanner, or wrench, depending on the hex size required. Supplied in a robust storage case, the set remains organised and protected between jobs.
