Flange Bolts Size Guide & Specifications
DYN Fasteners manufactures high-quality Flange Bolts designed for maximum strength, durability, and ease of assembly. These bolts feature an integrated washer-like flange that distributes the clamping load evenly, reducing the need for separate washers and ensuring superior fastening performance.
Our flange bolts are widely used in automotive, machinery, construction, and heavy equipment industries. Each bolt is precision-engineered and tested for tensile strength, dimensional accuracy, and corrosion resistance to meet international standards such as DIN 6921.
