FEATURES

The DIN933 standard is applicable to full-threaded hexagonal bolts with thread diameters of M6-M56, product grades A and B. Class A: d≤24mm and l≤10d or l≤150mm (according to the smaller value). Grade B: d>24 mm or l>10d or 1>150 mm. (Press the smaller value). Different product grades have different values for the corresponding opposite side s, diagonal e, thickness k and length tolerance.

The general thread diameter specification is M6-M56, and the general carbon steel performance grade is mainly 8.8 and 10.9. When d≤39mm, refer to ISO898-1.

Surface treatment and thread tolerance: DIN933 hexagon bolts are generally metric (coarse) and fine pitch, with mm millimeters as the unit of measurement. DIN933 coarse thread tolerance is: 6g, the coating is mainly boiled black, electroplating (blue and white zinc, yellow color zinc), non-electrolytic zinc powder coating (GEO). The tolerance matching before coating is mainly 6g/6H, and the tolerance zone matching after galvanizing can be changed to 6h/6G. However, after coating, it is affected by the thickness of the surface coating. When the thread is inspected by the corresponding tolerance, it is also There may be situations where it cannot be matched, and only nuts with matching specifications can be tested.
