I. DIN967 Standard Specification
DIN967 is a standard under the German Industrial Standards (DIN) that applies to cross-recessed pan head flange screws (i.e., round-head cross recessed machine screws). This standard sets out detailed and strict regulations on product dimensional specifications, technical delivery conditions, and other aspects, ensuring consistency and reliability in the quality and performance of products. Every parameter—from thread diameter and head size to screw length and cross-recess specification—is precisely defined to meet the needs of different industries and application scenarios. For instance, the thread size covers a variety of specifications ranging from M3 to M8, corresponding to different usage strength and connection requirements.
II. Analysis of Product Features
The most prominent appearance feature of the DIN967 round-head cross recessed machine screw is its round-head design. This shape not only has an aesthetic appeal but also prevents scratches on surrounding objects to a certain extent, making it suitable for occasions where appearance is a requirement. The cross-recess design enables better torque transmission when using a cross screwdriver. Compared with slotted (flat-head) screws, it is less likely to slip during tightening, which can improve installation efficiency and the firmness of the connection.
Beneath the head, there is a large disc-shaped flange (also called a washer). During installation, this flange increases the contact area with the connected part, distributes pressure, and prevents damage to the surface of the connected part. At the same time, it enhances the stability of the connection and effectively prevents loosening. Functionally equivalent to an integrated washer, it eliminates the need for a separate washer, simplifying the installation process.
III. Wide Range of Application Fields
Thanks to its excellent performance features, the DIN967 round-head cross recessed machine screw is widely used in numerous industries.
In the 3C (Computer, Communication, Consumer Electronics) manufacturing field, electronic products have compact internal structures and impose extremely high requirements on the precision and stability of components. The DIN967 round-head cross recessed machine screw, with its precise dimensions and reliable connection performance, is used to fix key components such as circuit boards and casings. This ensures that electronic products do not malfunction due to loose components during long-term use.
In the automotive manufacturing industry, the DIN967 screw is indispensable for engine assembly, body structure connection, and the fixing of interior components. Its high strength and stability enable it to withstand various vibrations and impacts during vehicle operation, safeguarding the safety performance of automobiles.
Additionally, it plays an important role in industries such as construction, rail transit equipment manufacturing, and medical device manufacturing, providing guarantees for the stable operation of various facilities and equipment.
IV. Material and Surface Treatment
Common materials for the DIN967 round-head cross recessed machine screw include plain carbon steel and stainless steel.
Plain carbon steel has a relatively low cost and a certain level of strength, making it suitable for general connection needs in ordinary environments. Stainless steel, on the other hand, has excellent corrosion resistance and can maintain stable performance in harsh environments such as humidity, acid, and alkali. It is often used in outdoor equipment, medical devices, and other occasions that require high corrosion resistance.
In terms of surface treatment, to further improve product performance and service life, treatments such as galvanizing, black oxide coating, and nickel plating are usually applied:
- Galvanizing forms a zinc protective film on the product surface, enhancing its rust resistance.
- Black oxide coating creates a dense oxide film on the surface, which not only provides rust protection but also improves the product’s aesthetic appeal.
- Nickel plating increases the surface hardness and gloss of the product while enhancing its corrosion resistance.
In summary, with its strict standard specifications, unique product features, wide application fields, and diverse material and surface treatment options, the DIN967 round-head cross recessed machine screw has become a reliable and important fastener in the field of industrial connections, continuously contributing to the development of various industries.
