Top 10 flange bolt Manufacturers in China 2025

Introduction to Flange Bolts

Flange bolts are a type of bolt with a circular flange under the head. This flange acts as an integrated washer, which provides a larger bearing surface area compared to a regular bolt. The larger bearing surface helps distribute the load more evenly, reducing the risk of damage to the connected parts and improving the overall stability and reliability of the joint. Flange bolts are widely used in various industries, such as automotive, machinery, construction, and pipeline systems, due to their excellent performance and convenience.
