SET SCREW M2*L3

What is Set Screws?

SET SCREW M2L3 is a common fastener, a type of internal thread fastener, widely used in machinery, electronics, automobiles and other fields. It is usually used to fix and adjust the position of machine parts or components. The specification of this screw is M2L3, that is, the thread diameter is 2mm and the length is 3mm. It fixes the parts by screwing into the internal thread of the object, and has strong stability and efficient fixing function.

Key Features:

1.Miniature size design, suitable for precision parts

The size of SET SCREW M2*L3 is metric thread M2, and the length is only 3 mm, which is an ultra-small fastener. This miniaturized design is very suitable for electronic components, small machinery, precision instruments, sensors, micro motors and other products with extremely high space constraints. It does not take up extra space and has strong adaptability and flexibility in high-density assembly occasions.

2.High-precision thread to ensure fastening effect

This specification of screws adopts precision machining technology, with high thread finish and stable precision. It can accurately match the corresponding threaded hole to ensure tightness and reliability during locking. Thread accuracy directly affects the uniform distribution of fastening force, reduces the structural stress caused by eccentric locking, and effectively improves the assembly quality and service life of the product.

3.Made of high-quality materials, strong durability

The common materials of SET SCREW M2*L3 include carbon steel, stainless steel (such as SUS304, SUS316), alloy steel, etc. These materials have good strength, toughness and corrosion resistance. After heat treatment, surface blackening, electrogalvanizing, nickel plating and other processes, not only the overall hardness is improved, but also its anti-rust and anti-oxidation ability is enhanced, which is suitable for a variety of complex working conditions, such as use in humid, high temperature and corrosive environments.

4.A variety of end forms are available to meet different applications

SET SCREW M2*L3 has different end forms according to different uses, including:

Flat Point: Suitable for occasions where the contact surface is not damaged, suitable for repeated disassembly positioning;

Cone Point: The end is in the shape of a pointed cone, which can penetrate into the surface of the other part, providing stronger positioning force and anti-slip performance;

Cup Point: The end is concave, which can fit closely with the shaft surface to improve the bite force;

Oval Point: Suitable for assembly structures that need to be adjusted frequently to avoid damage to parts.

This variety of end form selection can provide the best solution for different working conditions.

5.Hexagonal design, convenient and efficient installation

SET SCREW M2*L3 mostly adopts hexagonal hole design, which is convenient for assembly with standard hexagonal wrench. The hexagonal structure is not easy to slip, and the force is evenly applied when torque is applied, which can quickly complete the tightening operation, greatly improve assembly efficiency and reduce construction time. It can also be used efficiently in mass production lines and automated assembly processes.

6.Dual functions of positioning and fixing

SET SCREW can not only be used for ordinary tightening purposes, but more importantly, its **"headless" structural design makes it particularly suitable for concealed installation**, such as for locking parts such as wheels, gears or couplings firmly on the shaft. This hidden locking can provide good positioning and anti-rotation functions without destroying the overall appearance and size of the parts.

Advantages:

1.Compact size, suitable for precision equipment

SET SCREW M2\*L3 has a thread diameter of 2mm and a length of only 3mm. It is compact and suitable for use in places with limited space. It is widely used in micro-equipment such as electronic products, precision instruments, model assembly, etc., without affecting the overall beauty and compactness of the structure.

2.Stable and reliable fixing effect

This type of screw usually adopts a hexagon socket head design. Through the torque tool, the screw can be firmly pressed on the shaft or hole. It is particularly suitable for fixing gears, couplings, sleeves and other components to prevent loosening or slipping during movement or vibration, and improve the operating stability of the equipment.

3.Excellent material, wear-resistant and rust-proof

SET SCREW M2\*L3 is often made of high-strength carbon steel or stainless steel. The surface is blackened, electroplated or oxidized. It not only has good mechanical strength and wear resistance, but also can effectively prevent corrosion and rust, and extend service life.

4.Easy installation and maintenance

During installation, you only need to use a standard hexagonal wrench to complete the tightening. The operation is simple and does not require complex equipment support. When you need to replace or adjust the position, you can also quickly disassemble it to improve maintenance efficiency.

5.A variety of head types are available to adapt to different working conditions

SET SCREW M2\*L3 can be equipped with different head types according to usage requirements, such as flat end, cone end, cup end, etc. Different end types can provide different degrees of bite force and positioning accuracy to meet the technical requirements of various application scenarios.

Diverse Applications of Set Screws:

SET SCREW M2*L3 has a wide range of uses in various industrial applications, mainly used to fix or adjust the position of mechanical parts to prevent parts from loosening due to vibration or other factors. It is often used in situations where high strength and reliability are required, such as:

Mechanical assembly: used to connect small components in machine tools, equipment and mechanical devices.

Electronic products: In the assembly of electronic components, SET SCREW M2*L3 can be used to fix components to ensure that the components do not loosen during operation.

Automotive industry: In the connection and adjustment of automotive accessories, SET SCREW M2*L3 also plays an indispensable role, especially in the connection between the engine and the body.

Household appliances: In the assembly process of some small electrical appliances, such as the fixing of motors in household appliances, SET SCREW M2*L3 is also a common fastener.
