Metric Hex Tap Bolts, Stainless Steel A4 (316), M12-1.75 x 100M

Diameter - Thread Pitch: M12-1.75
  • Hex head for standard wrench or socket installation
  • A4 (316) stainless steel – marine-grade chloride and corrosion resistance
  • Known as a hex cap screw or tap bolt, these are fully threaded
  • Tensile strength in the range of 500–700 MPa
  • M12 x 1.75mm coarse thread pitch – multiple lengths available

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.  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.
