DIN 933 Duplex Bolt with hexagonal head and full thread

Overview

DIN 933 Duplex Hexagon Head Full Thread Bolt is a high-quality fastener with a hexagonal head and full thread that runs from the base of the head to the end of the shank. Made of duplex stainless steel, this bolt combines high strength and corrosion resistance, making it ideal for use in aggressive environments. Available in various strength grades, it provides a secure connection in structures where load resistance and service life are important.

Technical specifications

Technical specifications of DIN 933 Duplex bolt with hexagonal head and full thread:

• Standard: DIN 933, equivalent to ISO 4017
• Material: duplex steel, combining the properties of austenitic and ferritic stainless steels, providing high corrosion resistance
• Diameters: M6, M8, M10, M12, M14, and others
• Lengths: standard options from approximately 10 mm to 150 mm, depending on the selected diameter
• Thread pitch: metric thread, usually 1; 1.25; 1.5; 1.75 mm for diameters M6–M12, larger ones - according to standards
• Coating: depending on the specifics of use.

Analogs

Equivalents of DIN 933 Duplex:

• ISO 4017 - a standard corresponding to DIN 933, with a hexagonal head and full metric thread.
• GOST 7798-70 - a standard that is analogous to DIN 933 and ISO 4017.
