8-Piece Threading Set, Anti-corrosion Alloy Steel

【Anti-Slip Geometry】The integrated, burr-free, anti-slip geometry provides a smooth and precise engagement, preventing slippage or binding when manually threading bolts and pipes.
【Hardened Steel Core】The high-temperature hardened alloy steel core strengthens the cutting edges against deformation, enabling clean thread restoration on hardened steel, cast iron, and abrasive alloys.
【Corrosion Resistance】The polished alloy steel exterior resists oxidation in the workshop and moisture, preserving thread accuracy and extending the kit's operational life.
【Ferrous Metal Restoration】The kit easily cleans and restores internal and external threads on aluminum, malleable cast iron, carbon steel, and other hard-to-machine metals.
【Everyday Multi-Size Kit】Equipped with a variety of metric and standard thread pitches, this kit meets basic repair and manufacturing processes encountered in automotive maintenance and plumbing.
