### Proven Expertise in Fasteners Manufacturing
Founded by a team of industry veterans who have been active in the fasteners business since 2008, Qingdao Donsen International Trading Co., Ltd leverages over a decade of experience in delivering expertly engineered products. The company’s strategic location in Qingdao — a major industrial and shipping hub in China — provides a significant logistical advantage, facilitating efficient distribution to global markets.

### Flange Bolts: Precision Engineering for Secure Fastening
Flange bolts are specialized fasteners featuring a wide flange under the head that acts as an integrated washer, distributing the clamping load over a larger area. This feature helps increase the bearing surface, reducing the risk of damage to the parts being clamped and eliminating the need for a separate washer.
Recognizing the critical role flange bolts play in achieving strong, vibration-resistant joints, Qingdao Donsen has enhanced its manufacturing capabilities to serve customers seeking fasteners that guarantee long-term durability and safety. The company’s flange bolts are crafted from high-grade carbon steel and alloy steel, with options for various finishes such as zinc plating and black oxide to provide corrosion resistance and aesthetic appeal.
### Wide Range of Applications
Flange bolts produced by Qingdao Donsen International Trading Co., Ltd cater to multiple industries that require secure and reliable fastening solutions. Some of the primary applications include:
- **Automotive Industry:** Flange bolts are widely used in engine assembly, chassis fastening, and other critical automotive components where vibration resistance and load distribution are paramount.
- **Construction and Infrastructure:** The bolts offer reliable connections in steel structures, bridges, and heavy machinery assemblies.
- **Oil and Gas:** Their robustness and thread integrity make them suitable for onshore and offshore equipment that operates under extreme conditions.
- **Machinery Manufacturing:** The bolts ensure tight fastening of heavy-duty industrial machines that experience constant dynamic forces.
