Features and applications of stainless steel self-tapping screws

Stainless steel self-tapping screws are a kind of standard fastener whose primary function is to connect two or more parts firmly. Compared with standard screws, stainless steel self-tapping screws have better corrosion and oxidation resistance, so they are widely used in marine, chemical, petroleum, food and pharmaceutical fields.

Stainless steel self-tapping screws are usually manufactured from stainless steel (e.g., 304, 316, etc.), which is characterized by high strength, good corrosion resistance, and long life. At the same time, the head of stainless steel self-tapping screws is usually hexagonal or rounded to facilitate the use of wrenches or drivers for tightening.

The use of stainless steel self-tapping screws is very simple; you need to align the tip of the self-tapping screw with the part to be connected and then rotate it with force. The tip of the self-tapping screw can be used to punch a hole directly into the part, creating a thread that allows the thread to be securely fastened into the part.

Features of stainless steel self-tapping screws

Stainless steel self-tapping screws with a curved triangular cross-section of the thread for the ordinary thread, the thread surface also has a high degree of hardness, so in the connection, the screw can also be connected in the connection of the threaded bottom hole tapped out of the internal threads, to form a connection. This screw is characterized by low screwing torque and high locking performance, is better than ordinary self-tapping screws, has better working performance, and can be used instead of machine screws.

1. Wallboard self-tapping screws are used for the connection between the gypsum wallboard and metal keel. Its thread is a double-head thread; the thread surface also has a high hardness (≥ HRC53) and can not make a prefabricated hole under the conditions of fast screwing into the keel to form a connection.

2. Stainless steel self-drilling self-tapping screws and ordinary self-tapping screws is different from ordinary self-tapping screws in the connection, subject to drilling (drilling threaded holes) and tapping (including fastening connections) two processes, and self-drilling self-tapping screws in the connection, the drilling and tapping of the two processes are combined to be completed at once. It first drills holes with the drill in front of the screw and then taps with the screw (including fastening connections), saving construction time and improving construction efficiency.

3. Pan head and hexagonal head stainless steel tapping screws are suitable for the occasions where the drill bit is allowed to be exposed; hexagonal head tapping screws can be larger than the pan head tapping screws with enormous torque. The countersunk head and hexagonal flower-shaped self-tapping screws for nail head are not allowed to reveal the occasion; hexagonal flower-shaped self-tapping screws can be more than the passive head self-tapping screws with a more significant moment; semi-sedentary head self-tapping screws for nail head allowed to be slightly exposed to the occasion. Self-tapping screws when mounting and dismantling, slotted self-tapping screws need to use screw screws, cross slot self-tapping screws need to use cross-shaped screw screws, hexagonal flower-shaped self-tapping screws need to use hexagonal flower-shaped wrenches, hexagonal head self-tapping screws need to be used with dull wrenches, wrenches, socket wrenches, or live wrenches.

Stainless steel self-tapping screws have excellent corrosion resistance and high strength, so they are widely used in aviation, shipping, chemical industry, electric power, communications, construction and other fields.Stainless steel self-tapping screws, in addition to general screws, there also have critical anti-rust characteristics and long-term use, not easy to rust.
