Bolts, also known as screws or fasteners, are essential tools that utilize the principles of inclined plane circular rotation and friction force to tighten parts together. They are indispensable in both daily life and industrial production, often referred to as "industrial meters" due to their widespread importance.
| Automotive | In high-strength applications such as automotive engines, heavy-duty machinery, and bridge construction, they are preferred for their larger support area and better anti-loosening performance. |
| Mechanical | Used in mechanical, electronic, automotive, construction and other fields to connect various mechanical parts, circuit boards, engines, transmissions, building structures, etc. |
| Energy | For the energy industry, brackets and fixtures used to connect power generation equipment and transmission lines. |
| Architectural | In construction engineering, shipbuilding, and petrochemical industry, used to connect building structures, improve navigation safety and stability of ships, and ensure safety of petrochemical equipment. |
| Aluminum | Excellent thermal and electrical conductivity but naturally soft. May produce gelatinous buildup after processing and requires proper operation for cutting. |
| Titanium | EDM machining is well suited due to ability to withstand viscosity. Requires deionized water as medium to control heat during processing. |
| Steel | Very strong metal that generates significant heat during processing, requiring special precautions. |
| Brass | High tensile strength and easy to machine, but requires slow cutting speed due to softness. |
Good high-temperature performance: Stainless steel 316 offers better strength and oxidation resistance at high temperatures compared to the 304 series, making it suitable for high-temperature environments.
Ordinary bolt heads are very thick and difficult to deform, requiring re-tightening if vibration occurs. Flange bolts with thinner parts can slightly deform for a more secure lock. Flange bolts also allow tool access in confined spaces and provide better fastening in softer materials without causing perforation.
