Product information

The DIN933 standard is applicable to fully threaded hexagonal bolts with thread diameters M1.6-M52 and product grades A and B. Grade A: d≤24mm and l≤10d or l≤150mm (according to the smaller value). Grade B: d>24 mm or l>10d or 1>150mm. (according to the smaller value). Different product grades have different corresponding opposite side s, diagonal e, thickness k and length tolerance values.

The general thread diameter specifications are M3-M64, and the general carbon steel performance grades are mainly grade 8.8 and grade 10.9. When d≤39mm, refer to ISO898-1. Stainless steel is usually A2-50/A2-70/A4-70/A4-80. When d≤39mm,refer to ISO3506-1 or DIN267-11.

Surface treatment and thread tolerance: DIN933 hexagonal bolts are generally metric (coarse thread) and fine thread, measured in mm. The

tolerance of DIN933 coarse thread is: 6g. The coatings on the market mainly include black boiling, electroplating (blue and white zinc, yellow colored zinc) and non-electrolytic zinc powder covering coating (GEO). The tolerance fit before coating is mainly 6g/6H, and the tolerance zone fit after galvanizing can be 6h/6G. However, after coating, it is affected by the thickness of the surface coating. When testing the thread with a pass-and-stop gauge of the corresponding tolerance,it is also There may be situations where they cannot be matched, and only nuts with matching specifications can be installed and tested.
