Applications and Features of Stainless Steel Tapping Screws for Sheet Metal

For Stainless Steel Tapping Screws for Sheet Metal people who don't know much about screws don't know why they are called Stainless Steel Tapping Screws for Sheet Metal?

There are many kinds of Stainless Steel Tapping Screws for Sheet Metal: head hexagon, pan head, countersunk head, hexagon socket, bevel head, with pad head, the use of self-tapping locking, wall plate self-tapping, self-tapping self-drilling, ordinary self-tapping screws and so on.

Although there are many kinds of Stainless Steel Tapping Screws for Sheet Metal, such as a quick release fastener, all sorts of self-tapping screws still have some common points, such as material, heat treatment, hardness, surface treatment, production process, and so on.

Self-tapping screws must be heat-treated, such as carbon steel, to be carburized and stainless steel, to do solution hardening treatment to ensure that the self-tapping screws meet the relevant mechanical properties and performance standards. The production of self-tapping screws is used in the cold heading process, used mainly in high-speed cold heading machines and high-speed thread rolling machines or high-speed rolling machines; the reason why the emphasis on high speed because high-speed machine raw salt pumping self-tapping nails head molding is good, thread quality is also high, can guarantee the quality of the product.

18-8 Stainless Steel Phillips Rounded Head Screws for Sheet Metal: It refers to the screw head for the disk head, that is, rounded head, or called half-round head of stainless steel material self-tapping screws.

18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. They penetrate 0.025" and thinner sheet metal. Length is measured from under the head.

Super-Corrosion-Resistant 316 Stainless Steel Phillips Rounded Head Screws for Sheet Metal: More corrosion resistant than 18-8 stainless steel screws, these have excellent resistance to chemicals and salt water and may be mildly magnetic. They penetrate 0.025" and thinner sheet metal. Length is measured from under the head.

High-Strength 410 Stainless Steel Phillips Rounded Head Screws for Sheet Metal: Stronger and more wear-resistant than 18-8 and 316 stainless steel, these screws are magnetic and mildly chemical resistant. They're not for use with aluminum. Screws penetrate 0.025" and thinner sheet metal. Length is measured from under the head.

18-8 Stainless Steel Square-Drive Rounded Head Screws for Sheet Metal:18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. They penetrate 0.025" and thinner sheet metal. Length is measured from under the head.

Super-Corrosion-Resistant 316 Stainless Steel Square-Drive Rounded Head Screws for Sheet Metal: More corrosion resistant than 18-8 stainless steel screws, these have excellent resistance to chemicals and salt water and may be mildly magnetic. They penetrate 0.025" and thinner sheet metal. Length is measured from under the head.

Black-oxide stainless steel screws have a dark surface color.

It is used to connect the product material fastening role, make different materials and materials between the roles of the connection,d lot is ck and stabilize the material. When used without punching the bottom hole and tapping internal teeth, directly with the tool screwed into the product can be locked—Stainless Steel Tapping Screws for Sheet Metal in the drilling into the substrate after no chips out. Because the threads of Stainless Steel Tapping Screws for Sheet Metal are different from the general ones, the head is pointed. The pitch of the teeth is more significant, which is a bit similar to the chipless tapping screws, so it can be screwed in directly without tapping, and the metal and plastic are usually connected by this method.

The main features of stainless steel self-tapping screws include:

1. Material selection: usually made of carburized steel, can also be stainless steel or non-ferrous metals.

2. Heat treatment: the product must be heat-treated; carbon steel self-tapping screws need carburizing treatment, while stainless steel self-tapping screws need solution-hardening treatment to ensure that the mechanical properties and performance of use meet the standard requirements.

3. Surface treatment: the product surface hardness, core toughness, and the so-called "soft outside," which is a significant feature of the performance requirements of stainless steel self-tapping screws. If the surface hardness is low, it is difficult to screw into the matrix; if the core toughness is poor, it is easy to break. 4.

4. Protective treatment: The product surface needs protective treatment, generally electroplating. Some products need phosphate treatment (phosphating).

5. Production process: To ensure product quality, the production cold heading process recommends using a high-speed cold heading machine and high-speed thread rolling machine or planetary thread rolling machine. This production of stainless steel self-tapping screws head molding good, high thread quality，

Stainless steel self-tapping screws are favored because of their unique characteristics and a wide range of applications, such as high-speed rail, petrochemicals, glass curtain walls, electrical appliances, aviation manufacturing, hardware machinery, automotive, shipbuilding, lighting equipment, etc. These screws can be cemented in the material, relying on their threads. They will be cemented body "tapping - drilling, extrusion, pressure" out of the corresponding threads so that they fit each other closely to connect and fix a variety of materials effectively.

Stainless steel self-tapping screws and screws made of other materials are stainless steel screws with imitation rust, imitation corrosion, high temperature, and other good performance. One of our standard austenitic stainless steels has better overall performance, strength, and plasticity, and hardness is not high, which is conducive to molding.

Stainless steel self-tapping screws and machine screws to compare the advantages: machine screws in the connection of the installation need to be drilled and tapped, and self-tapping screws, as long as the drilling, do not need to be tapped, because the self-tapping screws in the screwing of their tapping, saving the time and cost of construction, the title of the high use of efficiency, and do not need to be used in conjunction with the use of the nut, the use of the more convenient.
