Coating Thread Inserts Plated With Tin And Zinc Inserts For Different Purposes

Information

1. The surface coating can be used for the surface treatment of different specifications and different purposes. It can be plated with silver, cadmium, tin and zinc.

2. The surface coating Thread Inserts is selected according to the specific requirements of the service environment. High temperature environment (aircraft engine) choose silver plating, eliminate potential difference (ship, radio wave) choose cadmium plating.

3. At the same time, it has all the functions of conventional Thread Inserts.

Wire thread insert is a new internal threaded fastener for threaded connection, and screwed into a threaded hole in the fastening member are connected in one, formed in standard thread, bolts (or screws) and then screwed wherein Also known as threaded wire sleeve, wire sleeve for short. It is a high-strength, high-precision, smooth surface of the cold-rolled stainless steel wire precision diamond machining made of a spring-like member concentric with and external thread, used to enhance the protection of the internal thread and of a low-strength material. The principle is to form an elastic connection between the screw and the thread in the base, eliminate thread manufacturing errors, and improve the connection strength. A threaded hole embedded wire thread insert engineering materials low strength aluminum, magnesium alloy, iron, steel, glass, plastic and the like, can be accurately formed in accordance with international standards of thread, having a high connection strength, shock, impact and wear-resistant Function, and can disperse stress to protect the thread of the base body, greatly extend the service life of the base body, and is widely used in electronic applications.

Specification

Advantage

1. Wire thread inserts are used in various low-strength materials, which can greatly improve the wear resistance of screw connections and avoid damage to the connecting threads.

2. Due to the certain elasticity of the wire thread insert, the load distribution on each circle of the thread can be more even, the pitch and tooth form deviation between the screw and the screw hole can be eliminated, and vibration can be absorbed, thus improving the connection strength and resistance Fatigue strength.

3. The locking wire thread insert can lock the screw in the threaded hole, so that the screw will not loosen when it is subjected to shock and vibration, and the process performance is better than that of the usual locking device.

4. Compared with the method of inserting steel or copper bushings, under the same strength conditions, screws with smaller size and higher strength can be selected, which can reduce the volume and reduce the weight.

5. The hardness of the wire thread insert is higher than that of the screw, so it is less worn during the assembly and disassembly process of the screw connection and can be used repeatedly. According to relevant experimental studies, the tensile strength of the wire thread insert is more than 7 times that of the screw, so the wire thread insert will not be damaged even if the screw is broken.

Application

1. Enhance connection strength and improve connection conditions. Low-strength materials such as aluminum and magnesium are selected for the wire thread insert, which can avoid slippage and wrong teeth, and obtain excellent connection performance.

2. Wear resistance. Used in frequently disassembled parts, it can greatly improve the service life of the thread.

3. Increase the bearing surface. It is used in places where strong connection force is required and the diameter of the screw hole cannot be increased.

4. Anti-loosening. It is especially used in occasions where products such as spacecraft require high insurance coefficients.

5. Easy to maintain. Install the damaged screw hole into the wire screw sleeve and continue to use it after repair to avoid the possibility of damage to the workpiece.
