We will provide detailed information about commonly used metric threads for fastening, including diagrams and tables.
In the fastening of mechanical structures (screw fasteners), screws are important components. They can be removed when necessary. The ability to repair mechanical structures and reuse them is a key feature. According to the screw fastening general rules (JIS B 1083:2008), screw fastening is defined as the method or state of joining two or more items by fitting the threaded part of a bolt with the nut or the internally threaded part formed in the item, and tightening the screw. A screw fastening assembly is defined as the entire structure with a screw fastening part or a part of the structure that includes the screw fastening part. Our technical information site "Screw Fastening Technology Navigation," which contributes to solving screw fastening challenges, provides detailed information about "the structure of screws." Please take a look through the related links. *For more details, please feel free to contact us.
