factory direct supply din967 cross recess coiled hair flange screw fastener

Product Features

• Head and Flange DesignThe head of the screw is in the form of a pan shape, with a cross slot at the top, which is convenient for using a screwdriver to tighten and loosen the operation. The flange is located below the screw head, which plays the role of increasing the contact area and distributing the pressure, making the connection more stable, and can prevent the screw from looseness to a certain extent.
• Material diversityCommon materials include carbon steel and stainless steel. Carbon steel materials such as 4.8-grade and 8.8-grade carbon steel have high strength and hardness, capable of withstanding large tensile and shearing forces, and are relatively inexpensive; stainless steel materials such as 304, 316, etc., have good corrosion resistance and beauty, suitable for humid, corrosive environments or places with high aesthetic requirements.1。

Specifications and Dimensions

• Diameter SpecificationThere are various sizes such as M2, M2.5, M3, M4, M5, M6, etc. The smallest diameter usually starts from M2, and the largest diameter can reach about M10, but the more commonly used specifications are between M2 and M6.1。
• Length RangeThe length specifications are diverse, with common sizes such as 6mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, and 30mm. You can choose the appropriate length based on your specific connection requirements.

Application field

• ElectronicsIn the assembly of the casings of electronic products such as computers, mobile phones, and televisions, the design of the pan head flange allows the screws to fit tightly against the casing surface after tightening, resulting in a beautiful appearance. The cross-slot design also facilitates automated assembly, improving production efficiency.
• Mechanical ManufacturingUsed for the connection and tightening of various machine tools, motors, pumps, fans, and other mechanical equipment, flange structures can increase the stability of the connection, reducing the possibility of screw looseness caused by vibration and impact during equipment operation.
• Furniture manufacturingScrews with a flange are often used in the assembly of furniture, such as tables, chairs, cabinets, and beds. These screws can make the surface of the furniture more flat and beautiful, avoiding the exposure of the screw head to affect the appearance and safety of the furniture. At the same time, they provide reliable tightening force.
• Automobile IndustryIn the connection of car engine, chassis, interior decoration and other parts, it can provide reliable tightening force. Its flange design can reduce the impact on the car appearance and improve the overall beauty and safety of the car.
