DIN931 and DIN933 are two different standards for hexagonal bolts in the German industrial standard. DIN931 bolts usually refer to hexagonal head bolts with partial threads, which are suitable for a variety of fastening needs.
DIN933 bolts refer to hexagonal head bolts with full threads, which are often used in situations where higher connection strength or longer connection length is required.
In terms of surface treatment, DIN931 and DIN933 hexagonal bolts can be treated with different surface treatment methods, such as black boiling, electroplating (blue-white zinc, yellow-colored zinc) or non-electrolytic zinc powder coating, etc., to improve their corrosion resistance and aesthetics.
Hexagonal head bolts have different performance grades, such as 8.8, 10.9 and 12.9, where the number represents the ratio of the tensile strength to the yield strength of the bolt.
