Double-ended bolts-also known as double-ended studs or stud bolts-are critical components in mechanical connections. Their unique feature lies in the threaded design at both ends, which allows for the selection of various specifications (including differing diameters) while being supported by the central shank.
【 Definition and Characteristics of Double-Ended Bolts 】
A double-ended bolt is a type of fastener featuring threads at both ends. Available in a wide variety of specifications, it can accommodate connection requirements involving different thicknesses and lengths. This design enables it to play a pivotal role across numerous industrial sectors.
【 Application Fields of Double-Ended Bolts 】
Double-ended bolts are widely utilized in diverse fields, including mining machinery, bridge construction, automotive manufacturing, motorcycle assembly, boiler steel structures, cranes, and large-scale architectural curtain walls. Their application in these areas underscores their indispensable status as connecting elements for heavy equipment and industrial applications.
【 Specifications and Materials of Double-Ended Bolts 】
Their specifications are typically denoted by information such as the nominal thread diameter (*d*), nominal length (*L*), and performance grade. Available specifications encompass a range of diameters and lengths, while common materials-such as Q235 steel and 45# carbon steel-are selected to suit applications requiring high-strength connections.
