Hexagon screw with partial thread DIN 931 M16x85-10.9 galvanized

Product detailed description

The partially threaded hexagon bolt according to DIN 931, also corresponding to ISO 4014, ČSN 021101 and EN 24014, is designed for applications requiring high strength and reliability. This bolt has a metric thread with a diameter of M16 and a length of 85 mm, with a thread pitch of 2.00 mm. The bolt is made of steel with a strength class of 10.9, which makes it suitable for use in demanding conditions where high tensile and shear strength is required.

The bolt head is hexagonal, with dimensions of width s 24 mm and width e 26.75 mm, with a head height k of 10 mm. This head shape allows for easy use of common tools such as wrenches and sockets for assembly and disassembly. The screw is equipped with a partial thread, which increases its strength in the joint and allows for better distribution of forces when used in structures.

The surface treatment of the screw is made with white zinc plating, which provides increased corrosion resistance and extends the life of the component in environments with higher humidity or chemical aggressiveness. This treatment is performed by galvanic zinc plating, which is subsequently baked, achieving high surface quality.

The screw is suitable for use in mechanical engineering, construction and various assembly assemblies, where high demands are placed on the strength and reliability of joints. It is ideal for fixed joints with higher stress, where it is necessary to ensure long-term stability and resistance to mechanical stress.
