Application and Features
1. DIN931 external hexagonal bolts with coarse threads are often used in conjunction with nuts. The threaded connection is used to connect the two parts into a whole, which is a detachable connection.
2. Fine-thread Plain Stainless Steel external hexagonal bolts are the same as coarse-thread ones, but fine-thread external hexagonal bolts have good self-locking performance and are mostly used in areas subject to large impact vibrations or alternating loads. They can also be used to adjust fine-tuning mechanisms. .
3. When using the external hexagonal bolts, pay attention to preventing them from loosening, otherwise they will affect normal work and cause accidents.
Anti-loosening methods include: friction anti-loosening, mechanical anti-loosening or other anti-loosening measures.
External hexagonal bolt connection is simple to assemble, easy to disassemble, highly efficient and widely used. It is mainly used in the production, installation and maintenance of various mechanical equipment, electronic products, communication equipment, furniture equipment, construction industry and other industries.
