Carbon Steel DIN 6921-1983 Hexagon flange bolts with standard design
Product details
Hexagon flange bolts thread specifications range from M5 to M20, with a pitch varying from 0.8mm to 2.5mm. The material is carbon steel, which has many grade to choose. According to customer needs, surface treatments such as blackening (heating or chemical), electric galvanizing, hot dipping zinc can be carried out to improve the corrosion resistance and aesthetics of bolts.Product tolerances and accuracy meet the relevant requirements of DIN standards to ensure the stability and reliability of product quality.
Product Characteristics
- Hexagonal head design: easy to use tools such as wrenches to tighten and loosen, improve work efficiency.
- Flange: located below the head, increases the contact area with the connector, enhances the fastening stability and anti-loosening performance. Flanges can be divided into two kinds according to demand, flat bottom and tooth, tooth flanges have better anti-slip effect.
- Screw: A cylinder with external threads used in conjunction with the nut to achieve a tight connection of two through hole parts.
- High quality materials: Made of high-quality steel or stainless steel to ensure sufficient strength and durability of the product.
ApplicationThe product is widely used in a variety of mechanical connections, because it has a large contact area and strong shear resistance, especially suitable for the need to bear a large lateral load or need good sealing performance occasions. Hexagon flange bolts are widely used in automobile engine, heavy machinery, crane and other important equipment and structures because of their excellent fastening performance and wide applicability.
