Description
The GB/T 35481 Hexagon Head Flange Bolts with Reduced Shank are specially designed for use in applications where precise torque, flexibility, and even load distribution are essential. The reduced shank design allows for improved fatigue resistance and performance under varying stress conditions, making them ideal for automotive assemblies, industrial equipment, and heavy machinery.
These bolts feature a hexagonal head with an integrated flange, which eliminates the need for a separate washer and distributes clamping load over a larger area. Manufactured from carbon steel or stainless steel, and available in strength grades 4.8, 8.8, 10.9, and 12.9, they offer robust mechanical performance and excellent corrosion resistance.
Surface treatments include plain, black oxide, zinc electroplating, hot dip galvanizing, copper plating, nickel plating, and zinc impregnation, providing reliable protection for indoor and outdoor environments.
These bolts conform to the GB/T 35481 standard and are cross-compatible with DIN, ISO, ANSI/ASTM, BS, and JIS standards. OEM customization is available per customer drawings or samples. Free samples are provided upon request. Packaged securely in wooden boxes, pallets, cartons, plastic bags, or nylon bags to meet shipping and storage needs.
