Hex head screw with toothed collar RIPP M8x20-10.9 without PU

Product detailed description

The RIPP M8x20-10.9 hex head screw with serrated collar is designed for applications where a reliable connection with high strength and resistance to loosening is required. This screw is made of grade 100 steel, which guarantees high tensile strength and resistance to mechanical stress. The strength grade 10.9 means that the minimum yield strength of the material is 900 MPa and the minimum tensile strength is 1000 MPa, which allows it to be used in demanding industrial applications.

The screw has a metric M8 thread with a pitch of 1.25 mm, which is a standard thread for this diameter, allowing compatibility with common nuts and threaded holes. The total length of the screw is 20 mm, while the diameter of the serrated collar head is 18.2 mm. The hexagonal head is 13 mm wide and 7 mm high, allowing easy handling with standard tools such as wrenches or sockets.

The serrated collar under the screw head increases the friction between the screw and the connected material, reducing the risk of the joint loosening due to vibration or dynamic loading. This design feature is particularly useful in applications where it is necessary to ensure long-term stability of the joint without the use of additional securing elements such as washers or adhesives.

The screw is supplied without surface treatment, which means that it is not protected against corrosion. Therefore, it is suitable for use in environments where it is not exposed to moisture or aggressive chemicals, or where additional surface treatment is planned according to specific project requirements. The screw is ideal for use in mechanical engineering, the automotive industry and other industries where high strength and reliability of joints are required.
