Hex flange bolts

Our hex flange bolts are engineered for secure, vibration-resistant fastening in automotive, construction, and industrial applications. The integrated washer-like flange under the head distributes clamping load evenly and eliminates the need for a separate washer, saving assembly time and improving joint integrity. We manufacture hex flange bolts to international standards including DIN 6921, ISO 4162, JIS B1189, and ANSI/ASME B18.2.1, with serrated or smooth flange faces. Available in a wide range of materials, grades, sizes, and surface finishes to meet your exact requirements. As an ISO 9001 certified fastener factory, we offer OEM/ODM services, consistent quality, and competitive wholesale pricing for distributors, OEMs, and construction projects worldwide.
