Hexagonal screw with collar DIN 6921 M6x25-8.8 galvanized

Product detailed description

Hexagonal bolt with collar according to DIN 6921, dimensions M6x25, is made of steel of strength class 8.8. This component is intended for applications where high strength and resistance to mechanical stress are required. The bolt is surface-treated with white zinc plating, which provides increased protection against corrosion, and is suitable for use in environments with moderate humidity.

The bolt head has a hexagonal shape with an integrated collar, which ensures better pressure distribution on the joined material and increases the stability of the joint. The head width (s) is 10 mm and the head height (k) is 6.6 mm. The collar diameter (dk) is 14.2 mm, which contributes to more efficient load transfer.

The bolt has a metric thread with a diameter of M6 and a pitch of 1.00 mm. The bolt length is 25 mm, while the thread length (b) is 18 mm. This type of thread is standardized and ensures a reliable connection with compatible nuts or threaded holes.

The screw is comparable to the EN 1665 standard and is part of the group of hexagonal collar screws, which are commonly used in mechanical engineering, the automotive industry and other industries where a strong and reliable connection is required.
