What Is Double End Stud Bolt?
A standard double end stud bolt is a metal stud with threaded sections at both ends and an unthreaded smooth middle section. One end screws into the tapped hole of the workpiece, while the other end passes through the mating part and is locked by hex nuts.
Most industrial‑grade double end studs are made of carbon steel, finished with black oxide treatment for anti‑rust performance. Common strength grades include 8.8, 10.9 and 12.9, covering metric sizes from M6 up to M48. Custom length and thread specifications are available for special project requirements.
Core Advantages of Double End Stud Bolt
- Strong tensile performance High‑strength double end stud bolt can bear large tensile load, suitable for heavy‑load equipment such as ball mills, crushers and pressure vessels. It maintains stable pre‑tightening force under continuous vibration.
- Adapt to narrow installation scenarios Without bolt head, it works well where there is no room for wrench operation on one side of the component. It is very popular for internal assembly of large mechanical equipment.
- Easy‑to‑maintain structure When parts need disassembly and replacement, only the nuts need to be removed. The stud itself can stay mounted on the base workpiece, reducing repeated disassembly damage to the base thread hole.
- Wide‑range material & grade options Carbon steel black oxide double end stud is the mainstream choice for general‑purpose heavy‑duty applications. For corrosive environment, stainless steel grades can be selected as alternative solutions. Standard compliance with DIN938, DIN939, GB/T901 guarantees interchangeability for global customers.
Main Application Scenarios for Double End Stud Bolt
- Mining industry: Fastening for ball mill, crusher and screening equipment, matched with high‑strength hex nuts.
- Mechanical manufacturing: Gear boxes, engine bases, large‑size equipment housing connection.
- Petrochemical & pressure vessel: Flange connection for pipelines and reaction tanks.
- Steel structure & construction: Heavy‑duty assembly for engineering equipment and support frames.
- Heavy‑duty truck & engineering vehicle: Chassis and component fastening.
