K-Cap Nut Overview

The K-cap nut is a special nut with a movable flower tooth pressed into one end of the hexagonal nut by stamping. From the side, its profile presents the shape of the letter “K”. It has a standard internal thread and can be used with a screw or bolt. The two semicircular openings make it easy to clamp or release the bolt or screw.

Advantages

• Excellent anti-loosening performance: The elasticity and anti-slip teeth of the flower tooth play a role when the nut is locked, and can tightly bite the bolt or screw with it, greatly reducing the risk of loosening under vibration, impact, and other working conditions. The anti-loosening effect is better than that of ordinary nuts.
• Easy installation: There are two openings. When installing and removing, there is no need to completely disengage like traditional hexagonal nuts. The nut can be directly inserted or removed from the bolt through the opening. The advantage is particularly obvious in some places with narrow space or inconvenient operation.
• Reduce wear: During the tightening process, the additional friction provided by the flower teeth is more evenly distributed, which can reduce the wear between the threads and thus extend the service life of the bolt or screw and the nut itself.
• Precise positioning: Compared with some ordinary nuts, the flower teeth of K-cap nuts can assist in positioning to a certain extent during installation, ensuring that the nut and bolt match more accurately and improving the installation quality.
• Wide range of applications: It can be made of a variety of materials, such as stainless steel, carbon steel, aluminum alloy, etc., which can adapt to different working environments and application scenarios, and meet the requirements of different industries for strength, corrosion resistance, and other performance.

Application

• Mechanical manufacturing: In various machine tools, industrial robots, transmission equipment, and other mechanical equipment, it is used to connect and fix key components, such as the connection between the motor shaft and the coupling, the installation and fixation of the gearbox, etc., which can ensure the stability of the connection of components during the operation of the equipment and prevent loosening due to vibration.
• Automobile manufacturing: Commonly used in automobile engines, chassis, body, and other parts, such as the assembly of engine cylinders, the connection of chassis suspension systems, the fixing of body interior parts, etc., to ensure the reliable connection of various components during driving and improve the safety and stability of the car.
• Electronic equipment: In the production of electronic equipment such as computers, mobile phones, and servers, it is used to fix circuit boards, radiators, housings, and other components to prevent components from loosening due to vibration during transportation and use, which can affect the performance of the equipment.
• Furniture industry: In the assembly of furniture such as tables, chairs, cabinets, and sofas, it can be used to connect metal frames, fix hardware accessories, etc., to ensure the firmness of the furniture structure and improve the quality and life of the furniture.
• Sports equipment: Such as bicycles, fitness equipment, etc., K-cap nuts can be used to connect and fix components such as frames, pedals, and handles to meet the requirements of sports equipment for component connection strength and stability during use.
