Stainless Steel SS304 ISO7380 DIN7985 Pan Flat Round Csk Head Machine Screw

Product Description

Product Description

    Machine screws are a common type of mechanical fasteners, usually used for fixing and connecting various mechanical components to ensure the stability and normal operation of equipment. They come in a variety of specifications and models to meet different application scenarios and assembly requirements.
 

Materials

Carbon Steel: It includes low carbon steel such as Q235, 1018, 1022, etc., which is used for products without hardness requirements; medium carbon steel such as No. 35 and No. 45 steel has higher strength and hardness; high carbon steel with a carbon content greater than 0.45% has high strength and hardness but poor toughness, and is less used.

Stainless Steel: There is austenitic stainless steel such as SS302, SS304, SS316, etc.

Alloy Steel: It is made by adding alloy elements to carbon steel, such as 42CrMo, etc., which can improve the strength, hardness, toughness and other properties of screws, and is used for components that bear large loads and work in harsh environments.

Copper Alloy: Brass is composed of copper and zinc, has good mechanical properties and processing performance, and is not easy to rust; bronze is composed of elements such as copper and tin, and has high strength, hardness, wear resistance, corrosion resistance and electrical conductivity.

Aluminum Alloy: It has a small density, light weight, good electrical conductivity, thermal conductivity and corrosion resistance, but relatively low strength, and is used in light-load application fields with strict weight requirements.

Titanium Alloy: It has superior corrosion resistance, heat resistance and high strength-to-weight ratio, can work stably for a long time in extremely harsh environments, but has a high cost, and is used in special occasions with extremely high requirements for material properties.

 

Product Parameters

 

Diameter	Common machine screw diameters include M2, M3, M4, M5, M6, M8, M10, etc. Screws of different diameters are suitable for connecting components with different thickness and strength requirements.
Length	The length range is relatively wide, ranging from a few millimeters to dozens of millimeters. Appropriate lengths of machine screws can be selected according to specific assembly requirements to ensure the stability of the connection.
Pitch	The pitch of coarse threads is relatively large. For example, the pitch of the coarse thread of M4 is 0.7 mm, while the pitch of fine threads is smaller. For example, the pitches of the fine threads of M4 include 0.5 mm, 0.35 mm and other different specifications.
Surface treatment	After surface treatment processes such as zinc plating, nickel plating, and blackening
