Square Taper Washers
Product introduction
Square tapered washers, specialized auxiliary fasteners, are designed for connecting inclined surfaces such as those of channel steel and I-beams. Their unique square shape with a sloped surface (commonly an 8% slope) seamlessly conforms to inclined surfaces, effectively preventing bolts from bending under load during nut tightening, ensuring stable and reliable connections. Available in diverse materials, carbon steel models offer cost-effective solutions for general industrial applications, while 304 and 316 stainless steel variants withstand harsh environments like moisture and chemical exposure. Some washers feature grooves on the surface, not only distinguishing between I-beam and channel steel types but also enhancing friction to prevent displacement during use.
The specifications of square tapered washers match closely with bolt sizes, typically ranging from M6 to M36, and are widely used in machinery, automotive manufacturing, electronics, and other fields. In the Chinese national standard system, GB 852 and GB 853 respectively standardize square tapered washers for I-beams and channel steel; internationally, the German DIN434 double-groove square tapered washers are commonly adopted. When in use, careful selection of material and size according to working conditions, correct installation of the sloped surface, and strict control of nut tightening torque are essential. With standardized design and flexible adaptability, square tapered washers have become indispensable components in industrial connections.
