Hexagonal screw with collar DIN 6921 M5x16-10.9 without PU

Product detailed description

The DIN 6921 hexagon socket head cap screw, size M5x16, is made of 10.9 grade steel and is supplied without surface treatment. This type of screw is characterized by a hexagonal head with an integrated collar, which increases the contact area and improves pressure distribution during assembly. The collar also helps prevent the screw from loosening due to vibrations.

The thread diameter is M5 with a metric pitch of 0.80 mm. The total length of the screw is 16 mm. The head width (wrench size) is 8 mm and the head height including the collar is 5.4 mm. The collar diameter is 11.58 mm, which provides sufficient stability in the application.

This screw is intended for use in applications where high strength and reliability are required. Strength class 10.9 means that the screw has a minimum yield strength of 900 MPa and a minimum tensile strength of 1000 MPa, making it suitable for demanding industrial applications where high demands are placed on the mechanical properties of the fastener.

DIN 6921 is equivalent to EN 1665, which defines the technical requirements for hexagon socket head cap screws. This component is ideal for use in the automotive industry, mechanical engineering and other areas where high strength and resistance to dynamic loads are required. The screw is supplied without surface treatment, which allows it to be further processed according to specific application requirements, such as electroplating or applying anti-corrosion coatings.
