Double headed bolt is a type of bolt with threads on both ends.

Its middle is usually the bare rod part, and the threads on both ends can be of the same specification or different specifications. Double headed bolts are commonly used to connect two thicker parts or components that require frequent disassembly.

Its advantages include:

1. Secure connection: It can provide reliable fastening force to ensure the stability of the connecting components.

2. Easy to disassemble: In situations where frequent disassembly is required, using double headed bolts is more convenient.

3. Adapt to different thicknesses: The position of the nut can be flexibly adjusted according to the thickness of the connecting components.

Double headed bolts are widely used in fields such as mechanical manufacturing, equipment installation, and construction engineering. Common materials include carbon steel, alloy steel, stainless steel, etc., to meet different working environments and strength requirements.

Here are some common double headed bolt standards:

GB/T 900-1988: This is a national standard for double headed bolts.

GB/T 897-901: Double headed bolts are manufactured according to this standard, and the materials used include Q235, 45 #, 40Cr, 35CrMoA, Q345D, etc. The specification range is M3mm-M100mm, and the length can be customized according to user needs.

The national standard for double headed bolts usually references other relevant standards, including the following:

GB 2: End of externally threaded parts for fasteners.

GB 196: Basic dimensions of ordinary threads.

GB 197: General thread tolerances and fit.

GB 1167: Transition fit threads (threaded into cast iron or steel bodies)

GB 1180: Overcurrent fit thread (screwed into aluminum bowl).

GB 3098.1: Mechanical properties of fasteners - Stainless steel bolts, screws, studs, and nuts.

GB 3098.6: Mechanical properties of fasteners - Stainless steel bolts, screws, studs, and nuts.

GB 3103.1: Fastener tolerances for bolts, screws, and nuts.

GB 5267: Electroplated coatings on threaded fasteners.

GB 5779.1: General Requirements for Surface Defects of Fasteners - Bolts, Screws, and Studs.

GB 5779.3: Special Requirements for Surface Defects of Fasteners - Bolts, Screws, and Studs.
