Introduction to Flange Bolts
Flange bolts are a type of fastener that combines the functions of a bolt and a washer. They have a circular flange under the head that acts as an integrated washer, providing a larger bearing surface area. This feature helps to distribute the load more evenly, reducing the risk of damage to the connected materials and preventing loosening due to vibration. Flange bolts are commonly used in various industries, including automotive, construction, machinery manufacturing, and piping systems, where reliable and secure connections are crucial. Flange Bolt
