DIN933 Hex Bolt

DIN933 is a hexagon bolt that conforms to the German standard. This type of bolt comes in full thread and is available in sizes ranging from M1.6 to M52. The carbon steel grades used in manufacturing the bolts are typically 4.8, 8.8, and 10.9. For metric coarse thread, DIN931 and DIN933 are the standard options, whereas for metric fine thread hex bolts, you have DIN960 and DIN961. In addition, you can also go for ASME hex bolts such as ASME B18.2.1 hex cap screws or hex heavy bolts, depending on your needs. And if you require JIS hex bolts, JIS B1180 hex bolts would be the ideal choice.

Hex head bolts come in various sizes and specifications, and it is important to understand the different standards that define their detailed dimensions. For instance, when looking at a specific hex bolt like the M10X30, these standards outline the specific hex head dimensions and thread dimensions that the bolt can be produced with. This information proves to be extremely helpful in understanding the exact requirements of customers when it comes to hex bolts. By referring to the standards, one can easily determine the specific dimensions and characteristics needed for a particular hex bolt, ensuring that the right product is provided to meet the customers' needs and specifications.

The prescribed tolerance fit for pre-galvanizing is 6g/6h, while the post-galvanizing factory belt fit can be altered to 6h/6g. However, the thickness of the surface coating impacts it following the coating process. Occasionally, when testing the corresponding GO or Stop gauge with the thread, it might fail to match. Thus, testing the nut installation is the only option available that meets the specifications. It is imperative to keep these factors in mind for optimal results.

DIN933 hex bolt are very widely used in the market. Because there are national standard, so many countries can use the same standard. The most material are carbon steel hex bolts and stainless steel hex bolts.

Because of its unique anti-corrosion ability and bright appearance, stainless steel hexagon bolts are widely used in environmental protection equipment, communication equipment, food machinery, power facilities, medical equipment, electronic products, petrochemicals, ship assembly, pump valve piping, building installation, etc. Production installation, repair and maintenance in the industry. Of course, in some specific locations in these fields, other products are also used, such as rail bolts, flange nuts, U-bolts, flat head hex bolts, T-bolts, round head square neck bolts and round head hex bolts.
