Damaged Screws & Bolts: This 8pc screw extractor set is engineered for right-hand threaded studs, bolts, large screws, and threaded pipes, making it ideal for stripped screw removal, broken bolt extraction, and flush-snapped fasteners where external extractors fail. Perfect for mechanic tools, automotive repairs, and industrial maintenance. Hardened Chromium-Vanadium Steel: Crafted from high-grade Cr-V steel, these extractors resist wear and deformation, ensuring reliable performance in impact socket sets, locking wheel nut removals, and heavy-duty bolt extraction. Built to handle rusted, corroded, or overtightened fasteners, when used correctly. Effortless Removal: Simply drill the broken bolt to the recommended size, then screw the corresponding extractor counter-clockwise for a tight grip. Ideal for rounded bolt removers, seized nut splitters, and DIY car repair kits, but requires proper technique to avoid tool breakage. Wide Range of Sizes (1 to 8): From small M3-M6 (3-6mm) screws to large M22-M26 (22-26mm) bolts, this extractor kit suits motorcycle repairs, exhaust fittings, and machinery maintenance. A must-have for professional-grade tool sets and serious DIY workshops. Expert-Recommended: Use with Caution! Designed primarily for loose or lightly stuck bolts, this set is NOT for average DIYers attempting seized stud removal without heat treatment. For rusted or frozen fixings, consult a highly experienced mechanic or exhaust fitter to prevent tool damage. Warning: Incorrect use can snap extractors!
