All-aluminum blind rivet The body of the rivet is also made of high-quality aluminum wire, which is beautiful and durable after riveting and will never rust: Compared with ordinary blind rivets, rivets have lower riveting strength and are suitable for connectors with relatively soft materials. . Split Stainless Steel Rivet: This rivet is a high-tension, corrosion-resistant choice. Round head rivets are mainly used in riveting occasions subject to large lateral loads, and are the most widely used. Flat cone head rivets are often used in riveting occasions with strong corrosion such as ship hulls, boiler water tanks, etc.

Customized Level 12.9

Ordinary nuts are suitable for use in fixed-load equipment. Ordinary nuts are used to fix on stationary workpieces and cooperate with flat and spring washers to ensure the reliability of the nut. However, on moving workpieces with vibration loads, the equipment may The vibration caused the nut to loosen. As a kind of nut, the slotted nut is used to connect the two mechanical equipment tightly. It is mainly used in the occasions with vibration load or alternating load. It is used in conjunction with the split pin to ensure the nut lock. The reliability of tightening is often used as a lock nut to prevent the main nut from loosening back.

The gasket side of the above-mentioned nut assembly is in contact with the mounting surface. When the nut is tightened, the gasket squeezes the outer cone surface to make it shrink, and the cone tip faces the same direction as the nut, thereby preventing the nut from tightening, so that the nut fixing effect is not good, and at the same time When multiple nuts need to be superimposed and fixed, two adjacent nuts cannot interact with each other, resulting in poor fixing effect.

How to use, what is a rivet nut? Usually, rivet nuts used inside elevators are used to install some kind of screws when installing various parts on cars or individual boards on aviation. Commonly used places are very important connection parts, so the choice of rivet nut material is very important. How to use the rivet nut? Let's watch it together. Rivet nuts are used in the fixing fields of various metal plates, pipes and other manufacturing industries, and are widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decoration. It is designed to solve the shortcomings of sheet metal, thin-walled pipe welding nut, substrate welding deformation, internal thread taper, etc. It does not require internal thread, welding nut, rivet efficiency, and is easy to use.
