Carbon Steel DIN 792-1976 Cylindrical countersunk head nib bolts Details
The design of the cylindrical countersunk head with tenon bolt combines the cylindrical countersunk head with the internal tenon structure and is designed for engineering applications that seek extreme performance and exquisite appearance.
Functional characteristics
Functional characteristics
- Cylindrical countersunk head design: The bolt head presents a round cylindrical shape, and when screwed into the pre-set countersunk hole, it can form an almost seamless fit with the workpiece surface, eliminating any possible protruding parts and providing a smooth, clean appearance interface.
- Built-in tenon structure: The end of the bolt is integrated with a tenon, which can accurately butt with the embedded mortise during installation, increase the firmness of the connection, prevent loosening when subjected to transverse or torsional forces, and ensure the stable connection between the structural components.
- High precision manufacturing standards: The use of advanced CNC machine tools and laser cutting technology to ensure that each bolt can achieve extremely strict tolerance control, so that the product has excellent interchangeability and assembly accuracy, reducing the time cost of field debugging.
- Selected material and treatment process: the main body is mostly made of high-strength stainless steel or special alloy, after quenching, tempering and a series of heat treatment processes, supplemented by plating, coating and other surface protection measures, in order to cope with various harsh environments, such as high temperature, corrosive gas and other challenges.
- Aerospace: In the connection of critical structural elements of aircraft skin, wing ribs, fuselage frame, etc., cylindrical countersunk head with tenon bolts through their precise mortise and tenon structure ensure the stability of the connection and shock absorption effect, while also reducing weight.
- Automotive industry: high-end models of the car outside the trim, hood, trunk lid and other locations, the use of such bolts can ensure the smooth connection, improve the appearance of the vehicle.
- Precision mechanical equipment: In the assembly of chip manufacturing, packaging and testing equipment, these bolts are used to connect high-precision positioning guides, fixtures and sensor brackets to ensure micrometer operating accuracy.
