Bolt DIN 933 M6x45 A2

Overview

DIN 933 A2-70 Hexagon head bolt with full thread is a reliable fastener with a hexagon head and a thread that runs from the head to the very end of the shaft. Made of A2-70 stainless steel, this bolt offers high corrosion resistance and strength under load. Its strength makes it the ideal choice for applications where reliability and durability of connections are important, particularly in outdoor environments.

Technical specifications

Technical characteristics of DIN 933 A2-70 bolt with hexagonal head and full thread:

• Standard: DIN 933, equivalent to ISO 4017
• Material: A2 stainless steel, which provides high corrosion resistance
• Strength class: 70, which guarantees good mechanical strength and reliability
• Diameters: M6, M8, M10, M12, M14, and other options are available
• Lengths: standard options from approximately 10 mm to 150 mm, depending on the selected diameter
• Thread pitch: metric thread with typical pitches of 1; 1.25; 1.5; 1.75 mm for diameters M6–M12, as well as larger ones in accordance with the standard
• Coating: no additional coating, as stainless steel already has high corrosion resistance, but options with other coatings may be available depending on operating conditions.
