JX2407 SPECIAL DESIGNED MULTI STEP MACHINE BOLT
Coarse Thread: Coarse - thread mechanical screws have a relatively large pitch between threads. They are easy to install and provide strong fastening in applications where high precision is not required. Coarse - thread screws are often used in woodworking and some general - purpose mechanical assemblies.
Fine Thread: Fine - thread screws have a smaller pitch, which allows for more precise adjustment and higher holding power. They are suitable for applications where a tight and secure connection is needed, such as in precision mechanical systems and some high - load - bearing structures.
