General description

DIN 7984 is a bolt (screw) with an internal star drive (Torx) or hex socket for a wrench and a cylinder head. The screw shank has a partial metric thread. The Torx or hex socket bolt is used for joining structural elements in mechanical engineering, instrument making, and other industrial, manufacturing and construction sectors, together with nuts and washers of corresponding sizes.

The DIN 7984 Torx bolt is made of carbon steel, A2 and A4 stainless steel, brass. A screw made of zinc-plated steel can be additionally galvanized.

Applications

The bolt is used in mechanical engineering, construction, furniture manufacturing, and everywhere dynamic, cyclic and impact loads are present. It is used in pressurized engine units. The material for manufacturing bolts is selected from low-carbon steels, alloy steels and alloys with high corrosion resistance.
