M2 screw

M2 screws are small fasteners used in a wide range of applications, such as automotive, electronic equipment, and construction. The M2 refers to the metric diameter screw thread, which is about 2 millimeters. These screws are available in different lengths, materials, head types, and finishes to suit specific applications. Some screws are self-tapping with a sharp point and threads that cut into the material with ease. Buy M2 screws in bulk and get discounted prices for your retail store on Alibaba.com.

Head type of M2 screws

The head type of M2 screws varies to serve different purposes. Pan head M2 screws have a large diameter with a rounded head and flat underside. They are common in applications that require a raised finish. These screws can handle high torque as the head diameter offers a good clamping force. Flat pan head screws have a flat head with a cone-shaped underside. They sit flush with the surface, providing a smooth and seamless finish. Button head M2 screws have rounded top surfaces with a larger diameter than pan head screws. They provide a decorative finish while offering good bearing and clamping force. Button head screws are well-suited for applications that require a functional fastener with an aesthetic touch. Hex head screws have a cylindrical head with an internal hexagonal socket drive. The hex head design allows for greater torque and force applied on the screw head. They require a socket, Allen key, or wrench to drive in the screw.

Material and finishes of M2 screws

Different types of materials, such as steel, stainless steel, carbon steel, aluminum, plastic, and titanium are used to make M2 screws. Many 2mm screws are made of steel because they are strong and durable. Stainless steel screws offer excellent rust and corrosion resistance. They are a great choice for outdoor or marine applications. Aluminum screws are lightweight and corrosion-resistant. They work well in applications where low weight is an important factor. Titanium M2 screws are strong, lightweight, and resistant to corrosion. They cost more and are commonly used in medical and aerospace applications. Plastic M2 screws are less expensive and resistant to corrosion and chemicals. They don’t conduct electricity to suit most electrical applications.

M2 screw sizes have coatings or finishes that enhance appearance and provide extra protection. Zinc-plated screws have a shiny silver or yellow finish that fights corrosion. Black oxide finish gives M2 screws an attractive black or dark gray appearance. Nickel-plated M2 screws offer a smooth, lustrous finish and corrosion resistance. They are suitable for both decorative and functional purposes.
