The Sealey 9 Piece Stud and Bolt Extractor Set is a professional extraction tool kit designed for removing broken or damaged studs and bolts from engines, machinery and equipment. This comprehensive set provides mechanics and engineers with the essential sizes needed to tackle seized fasteners across a range of applications. Featuring a left-hand tapered spiral design, each extractor bites progressively tighter into the pre-drilled stud or bolt as more torque is applied, ensuring a secure grip on damaged fasteners. The set includes extractors in two drive sizes: 3/8" square/17mm hex drive for smaller fasteners (2, 3, 4, 5, 6mm at 36mm length) and 1/2" square/22mm hex for larger applications (8, 10, 12, 14mm at 45mm length). Ideal for automotive workshops, plant maintenance and general engineering tasks, the extractors are supplied on a socket rail for organised storage. The dual drive configuration allows use with both ratchets and spanners, providing versatility when working in restricted access areas where different tool approaches may be required.
