Metric hex head screws / bolts part thread, defined in the DIN 960 standard published by the German Institute for Standardization (DIN), are externally threaded fasteners with a hexagonal washer-face head and a chamfered end to facilitate mating with an internally threaded component. Hex screws have a fully threaded, fine-threaded body and are manufactured to very tight tolerances. Hex head screws / bolt piece thread are manufactured in fine thread, plain and zinc plated steel, in diameters ranging from M8 to M24 and in lengths up to 150 mm.
Similarly, the ISO 8765 standard published by the International Standards Organization (ISO) describes the characteristics of hex head bolts with metric fine pitch threads with nominal thread diameters from 8 mm to 64 mm. This standard applies to product class A, nominal thread diameters from 8 mm to 24 mm and nominal lengths up to 150 mm, whichever is shorter, and product class B, nominal thread diameters over 24 mm or nominal lengths over 150 mm. Includes products for lengths (whichever is shorter).
Again in the ISO 8765 standard, the characteristics of metric fine pitch threaded hex head screws with nominal thread diameters from 8 mm to 64 mm are described. This standard applies to product class A for nominal thread diameters from 8 mm to 24 mm and nominal lengths up to 150 mm, whichever is shorter, and product class B for nominal thread diameters over 24 mm or nominal lengths over 150 mm Includes products for (whichever is shorter).
Our organization, among the numerous tests, measurements, analyses, and evaluations it provides for businesses in various sectors, also offers testing services for hexagonal head screws/bolts with fine threads according to the DIN 960 standard, for metric fine-pitch hexagonal head bolts according to the ISO 8765 standard, and for metric fine-pitch hexagonal head screws according to the ISO 8676 standard, with its trained and expert staff and advanced technological equipment.
