M16 Hex Bolts

M16 Hex Bolts are externally threaded fasteners with a six-sided head, designed for general-purpose mechanical and structural fastening. The M16 designation indicates a bolt with a 16 mm nominal diameter, following ISO and DIN metric standards. These bolts are widely used due to their ease of installation and ability to transmit high clamping forces. Zeron Fastners supplies M16 Hex Bolts in a variety of materials, including high-tensile carbon steel (Grade 8.8 and 10.9) for heavy machinery and structural connections, and stainless steel (A2/304 and A4/316) for corrosion resistance in construction, automotive, and general manufacturing industries.
