There are various specifications for self tapping screws, including diameters ranging from 3mm to 12mm and lengths ranging from 10mm to 100mm. The specific specifications will also be adjusted according to different application scenarios and materials.

The classification and specifications of drill tail screws can be divided into various types based on their use, material, and shape, such as cross groove pan head self tapping screws, cross groove countersunk head self tapping screws, hexagonal flange self tapping screws, etc.

Spring washer’ usually refers to a spring washer. It is a commonly used anti loosening component in fastening connectors. By its own elastic deformation, a continuous pressure is applied to the threaded connection after tightening the bolt or nut, thereby increasing friction and preventing loosening. There are various types of elastic pads, including standard, light, heavy, etc. Different types have differences in elasticity, size, etc., to adapt to different working conditions and connection requirements.

Flat washer DIN125 Grade: 4.8, 8.8, 10.9, 12.9 Material: Q235, 35K, 45K, 40Cr, 35Crmo, 42Crmo, Surface Treatment: Blackened, Electrogalvanized, Dacromet, Hot-dip Galvanized, Galvanized, etc! Flat pad is a type of gasket that is flat in shape. Its main functions include: increasing the contact area, dispersing pressure, and protecting the surface of the connected parts from scratches; Reduce the pressure damage of nut or bolt heads on the surface of the connected parts; Sometimes it can also play an auxiliary role in preventing loosening. There are various materials for flat pads, including metal (such as carbon steel, stainless steel, etc.), plastic, rubber, etc. Its size and specifications vary depending on the usage scenario and the requirements of the connecting components.

Square gasket is a type of square washer. It is usually used to increase the contact area between the connecting piece and the connected piece, disperse pressure, reduce wear, and protect the surfaces of the connecting piece and the connected piece.

Fish tail bolt, also known as fish tail bolt or fish tail screw, is a commonly used fastener for railway track connections. Its shape resembles a fish tail, hence its name. Fish tail plugs are usually made of high-strength steel, which has good tensile strength and fatigue resistance. Its main function is to tightly connect the steel rails and sleepers together, ensuring the stability and safety of the railway track. The specifications and dimensions of fish tail bolts may vary depending on the type of steel rail and sleeper. When installing and using fishtail bolts, it is necessary to strictly follow relevant standards and specifications to ensure their fastening effect and the safety and reliability of railway operation.

Grade: 4.8, 8.8, 10.9, 12.9, Material: Q235, 35K, 45K, 40Cr, 20Mn Tib, 35Crmo, 42Crmo, Surface Treatment: Blackened, Electrogalvanized, Dacromet, Hot-dip Galvanized, Galvanized, etc!

A flange bolt is a type of bolt with a flange on the head. Its characteristics include: Increase contact area: The presence of flanges increases the contact area between bolts and connectors, disperses pressure, and reduces damage to the surface of connectors. Improve anti loosening performance: Compared with ordinary bolts, flange bolts have better anti loosening effect in vibration environments. Easy installation: The edges of the flange are usually chamfered or rounded, making it easy to install and position.

Grade: 4.8, 8.8, 10.9, 12.9, Material: Q235, 35K, 45K, 40Cr, 35Crmo, 42Crmo, Surface Treatment: Blackened, Electrogalvanized, Dacromet, Hot-dip Galvanized, Galvanized, etc!
