3mm 4mm 6mm Stainless Steel Tubular Rivets SUS304 316 316L Semi Tube Rivet

3mm 4mm 6mm Stainless Steel SUS 304 316 316L Flat Head Semi Tubular Rivet DIN7338

1,Description:

A rivet is a mechanical fastener or connector with the head and tail on opposite sides. It has a head, a smooth cylinder, and a tail that looks more like a metal needle.

Rivets are usually made of aluminum or steel, but some are made of other materials. These types of fasteners are not tightened like the usual bolts and nuts. The use of a unique rivet mounting method helps ensure permanent part assembly or connection.

The rivet is installed in a drill hole that is approximately 1.5 mm larger than the diameter of the rivet itself to better hold the rivet in place. Once the rivets are installed, the tail will come out the other end and deform there. When you hit or smash the tail of the rivet, it flattens the material, which usually causes the tail to unfold or unfold. It expands to about one and a half times its original size. In other words, you can create a dumbbell-sized rivet by tapping or pulling to snap the tail off one end and create a new head on the other. After that, the tail is dumbbell shaped. In this way, the joint is riveted

3,Specifications:

Hollow rivet: hollow end

Full hollow rivets - they have deeper holes than their counterparts. They are also generally weaker than semi-tubular rivets. However, they can easily Pierce softer materials such as fabrics and plastics.

Countersunk Head Open End Blind Rivets With Aluminum Mandrel And Head DIN7337

Solid rivets: The most common type of rivets

These rivets are the most common type of rivets. They are simple, reliable and the oldest form of connection material.The headless part of the other end is deformed using a rivet gun or hammer. A solid rivet consists only of a shaft and head, which can be deformed using a rivet gun or hammer. These types of rivets can be equipped with a 100 degree countersunk head or a round universal head. Solid rivets are often used in situations where safety and reliability are critical. For example, one typical application is the structural parts of aircraft. These simple tools consist of a solid shaft that, once punched, will have a head on a specific side.

Blind rivets: also known as pop rivets

Blind rivets are also known as hollow or pop rivets. These metal rivets are tubular fasteners with a mandrel in the center. The manufacturer inserts blind rivets into the drill holes on the parts for joining. The blind end of the rivet expands, causing the mandrel to break. Unlike solid rivets, you can install blind rivets in the joint from the side of the part. In this way, they are "blind" to the other side. Cored rivets are suitable for situations where the back end of the joint is difficult to see. As with any other rivet, its application is very simple and fast. It is the most important combination of aerospace, electronics and shipbuilding industries.

Some common blind rivets available are: Pull core rivets - are special double countersunk blind rivets that provide flush surface rivets on both sides of their application. Here, the mandrel head does not fall off, providing a consistent clamping force. In addition, the tight radial setting in these rivets increases the structural stiffness. Threaded rivets - also known as blind riveted nuts or threaded inserts. 

The manufacturer can fix this variant of the standard blind rivet from the side of the mounting part. Available with standard and heavy threaded rivets. The standard options satisfy almost all permanently installed blind applications. However, heavy rivets have heavy side walls and heads. As such, they contribute to high-performance and more demanding applications. Drive pin rivets - These types of core-pulling rivets have short mandrel protruding from their head. Once the drive pin rivet is inserted into the hole, its mandrel can be worked with a hammer or other material. This opens the end of the rivet in the hole. Drive pin rivets are more popular in construction and other aesthetic applications because they do not require drilling. However, you must note that they have less clamping force compared to many other types of rivets.

4,Feature Advantage:

Stainless steel screw surface corrosion prevention treatment refers to the use of various methods to apply a maintenance layer on the metal surface, its role is to isolate the metal and the corrosive environment, to inhibit the corrosion process, or reduce the corrosive medium and the metal surface contact, so as to avoid or reduce the purpose of corrosion.

Corrosion resistance, wear resistance, high hardness,

Stainless steel screws are made of metal, and metal corrosion prevention methods mainly have four aspects, that is, the nature of the material itself, the use of the environment, the interface of data and the environment and the improvement of metal structure design, if the use of complete corrosion resistant alloy to manufacture stainless steel screws, unless there are special needs, otherwise in the economic concept is not cost-effective, It is also impractical to completely isolate the external surface of the screw from corrosive environmental elements. Improved metal structure design can improve the impact of special circumstances in a certain situation, but the design of most stainless steel screws can not be fully corrected, and its maintenance role is not permanent, so this method can not deal with the basic problem, as long as the surface corrosion prevention, that is, the appearance of corrosion prevention treatment is the most widely used method.
