Heavy Duty Screw Extractor

EXTRACUT Heavy-Duty Screw Extractors industrial-grade fastener removal tools engineered for the most challenging extraction scenarios: large-diameter corroded bolts, snapped-off studs in engines and machinery, and seized fasteners that have been exposed to extreme heat, chemicals, or years of environmental exposure. Built from premium alloy steel with aggressive flute geometry, these extractors generate the gripping force needed to break free fasteners that would destroy standard extractors.

Key Features

• Aggressive Spiral Flute Profile — Deeper, coarser spiral flutes with increased helix angle generate 40% more gripping torque than standard extractors on large-diameter fasteners.
• Large-Diameter Capacity — Sizes up to M25 (1") and beyond for heavy industrial fasteners found in construction equipment, mining machinery, and marine engines.
• Impact-Rated Construction — Designed to withstand hammer-assisted extraction technique where impact blows help break corrosion bonds.
• Premium HSS-Co Material — Cobalt-alloyed high-speed steel (M42 equivalent) provides the hardness and heat resistance needed for large-bolt extraction.
• Pilot Drill Integration — Larger sizes include integrated pilot drill point for the "drill-out then extract" technique on completely destroyed fastener heads.
• Industrial Packaging — Heavy-duty storage case with individual compartments protects each extractor and includes size reference chart.

Applications

Heavy equipment maintenance (excavator, bulldozer, loader track and chassis bolts), marine engine overhaul (seized cylinder head and exhaust manifold studs), mining machinery (crusher and conveyor drive bolts), oil & gas (wellhead and valve body fasteners), bridge and structural steel (corroded high-strength bolts), and any industrial scenario involving large-diameter (>M12) severely damaged or seized fasteners.
