GB897B is a specification for double stud full thread stud specified in the Chinese national standard. Characterized by threads on both ends and a smooth rod in the middle, these double-ended studs are typically used to connect two thicker components, where a threaded hole in one component accommodates one end of the stud and the other end passes through a through-hole in the other component and is used with a nut.

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

HIGH STRENGTH: GB897B double-ended studs are usually made of high-strength materials and are able to withstand large preloads and working loads. RELIABILITY: With threads on both ends, these studs provide a reliable connection for applications requiring high strength connections. Reusable: Compared to welded or other permanent connections, double-ended studs allow for disassembly and reuse for easy maintenance and repair. Versatility: GB897B standard double-ended studs are available in a wide range of sizes and lengths to suit different applications.

Scope of Application

Mechanical connections: In mechanical manufacturing, double head bolts are commonly used to connect parts that require high strength connections, such as engine parts, pumps and compressors. Steel construction: In steel construction, double head bolts are used to connect beams, columns and other structural components, especially where high strength and removability are required. Bridge construction: In bridge construction, double-ended bolts are used to connect various parts of the bridge, such as the deck and supporting structures. Mining Machinery: In mining machinery, double head bolts are used to connect heavy mechanical components such as excavators and drilling rigs.
