The integrated flange replaces the separate washers, which not only increases the friction between the screws and the contact surface, but also distributes the pressure, so that the screws remain stable for a long time after installation.\nSuper anti-loosening: The design of the flat screws with flange provides greater locking force and prevents the screw from loosening due to vibrations. The flange design also increases the contact surface between the screw and the contact surface, which further improves the anti-loosening performance.\nHigh-quality materials: The flat screws with torx are made of stainless steel, which has excellent tensile strength and shear strength. This material not only ensures the stability of the screws under heavy load, but also their performance in extreme environments.\nWide range of applications: Flat screws with countersink are very suitable for applications in areas that require high reliability and long service life, such as vehicles, aviation, mechanical engineering, precision instruments, model building, etc. Machine screws with washers can effectively prevent the screws from loosening and ensure a long-lasting fastening effect.\nProduct parameters: Size: M6 x 20 mm; Quantity: 20 pieces; Material: 304 stainless steel (A2).
