DIN 931 10,9 zinc hex Bolt with partial thread

Overview

The DIN 931 bolt with strength class 10.9 has a hexagonal head and partial metric thread. In this case, the thread covers only part of the shank, while the rest remains smooth, which reduces friction and ensures stability of the connection. Diameters range from M6 to M36 and can be customised to project requirements, in accordance with metric thread standards. The use of DIN 931 bolts is appropriate in situations where high strength and reliability of the connection are important, and the smooth part of the shank allows them to be used as support elements. These bolts are often used in mechanical engineering and construction, where increased breaking and deformation characteristics are required.

Technical specifications

Technical specifications for DIN 931 hexagon head bolts with partial thread, class 10.9, zinc-plated:

• Nominal diameters: from M8 to M30 mm.
• Thread pitch: metric standards, in particular, M8-1.25; M10-1.5; M12-1.75; M16-2.0 and others.
• Thread length: for bolts with a length of L ≤ 125 mm - approximately 15-25 mm, for L from 125 to 200 mm and above - in accordance with the standard.
• Strength class: 10.9, which provides high resistance to mechanical loads, especially in structures requiring reliability.
