Description
The DIN 34801 Hexalobular Head Bolts with Large Flange are high-performance fasteners featuring an external hexalobular drive (Torx® style) for improved torque transfer and reduced cam-out compared to standard hex or Phillips drives. These bolts are designed with a large integrated flange, providing increased bearing surface, which distributes clamping forces evenly—minimizing surface damage and improving joint security.
Ideal for automotive assemblies, machinery, electronics, and heavy equipment, these bolts are manufactured using premium carbon steel or stainless steel, and are available in grades 4.8, 8.8, 10.9, and 12.9 to meet varying strength requirements.
A wide range of surface finishes are offered—including plain, black oxide, zinc electroplating, hot dip galvanizing, copper plating, nickel plating, and zinc impregnation—to suit diverse environmental and corrosion resistance needs.
Fully compliant with DIN 34801, these bolts are also compatible with GB, ISO, ANSI/ASTM, BS, JIS standards. OEM services are available for non-standard sizes or customized designs, based on your drawings or samples. Free samples are available upon request.
