bolt stud
Exhibitor Information
Handan Yongnian District Jihao fastener manufacturing Co., LTD
A bolt, particularly referring to larger-diameter fasteners, may also be headless, such as double-ended bolts. Typically, these are not called "bolts" but rather "studs", with the most common double-ended stud design featuring threaded ends and a polished central shaft.

Main Applications: Designed for large equipment requiring accessory installation. Examples include observation lenses, mechanical seal seats, and speed reducers. In such cases, double-ended bolts are used where one end is screwed into the main body and the other end into the accessory. After installation, a nut is attached to the end. Since accessories are frequently removed, threads can wear out or become damaged. The use of double-ended bolts makes replacement very convenient.
