factory direct supply din968 cross headband introduction self-threading pin fastener

Standard and Specification

• Standard VersionThere are versions such as DIN968-1994, DIN968-2002, and DIN968-2008, and the current effective version is DIN968-2008.5。
• Specification RangeThe standard specifies the dimensions from ST2.9 to ST6.3, product grade A for cross-reinforced cap head self-tapping screws with a screw thread and a clamp ring.5。

Product Features

• Head with cross-slot designThe head is in the shape of a pan, with a cross-shaped groove at the top, which is convenient for using a screwdriver to tighten and remove the operation. The design of the cross-shaped groove can achieve automatic installation and disassembly, improving the assembly efficiency.
• "带介结构"可以翻译为"with an intermediary structure"。With a card sleeve, that is, a shim, it can increase the contact area and distribute the pressure, making the connection more stable, and at the same time, it can prevent the screw from loosening 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 and 316 have good corrosion resistance.With aesthetics and suitability for humid, corrosive environments or situations with high aesthetic requirements.1。

Application field

• ElectronicsIn the assembly of the casings of electronic products such as computers, mobile phones, and televisions, the design of the headless with insert 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, the medium structure can increase the stability of the connection, reducing the loosening of the screws due to vibration and impact during equipment operation.
• Furniture manufacturingScrew with a plate head is often used in the assembly of furniture, such as tables, chairs, cabinets, and beds. This type of screw 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, it provides a reliable tightening force.
• Automobile IndustryIn the connection of car engine, chassis, interior decoration and other parts, it can provide reliable tightening force. The design of the medium can reduce the impact on the appearance of the car and improve the overall beauty and safety of the car.
