This M12 x 1.75mm hex tap bolt is manufactured from A4 (316) stainless steel, providing superior corrosion resistance in marine, coastal, chemical processing, and other demanding environments where standard 18-8 stainless falls short. The partial thread design leaves an unthreaded shank section below the hex head, reducing stress concentration at the bolt-to-joint interface and providing improved shear strength compared to fully threaded alternatives. A4 stainless contains molybdenum for enhanced resistance to pitting and crevice corrosion from chlorides and saltwater, making these tap bolts ideal for boat hardware, dock fittings, food processing equipment, and any application where long-term corrosion performance is essential.
