This product is a non-standard customized combination screw with a pan head cross groove structure, equipped with pre installed plastic gaskets and a guide tail design, which balances fastening stability and assembly convenience. It is suitable for precision assembly scenarios that require surface protection and installation efficiency. The overall appearance is treated in black, combining functionality and visual unity.
The screw head adopts a disc head design, with a large force area, which can effectively disperse pressure during the locking process and reduce the risk of indentation on the surface of the connected part.
Combined with pre installed plastic gaskets, a buffer layer can be formed during the fastening process, which can protect the surface, isolate contact, and reduce vibration transmission. It is particularly suitable for the connection requirements of electronic product casings or precision structural components.
The tail of the product is designed as a guiding section structure, which can play a pre positioning role in the actual assembly process, making it easier for screws to align with the installation holes.
This structure reduces assembly deviation and improves locking efficiency. It is particularly practical in automated assembly or space constrained environments, effectively improving the smoothness of operations.
This type of non-standard combination screw is widely used in electronic devices, household appliances, precision instruments, and automation equipment structures, especially suitable for application scenarios that require a balance between fastening strength and surface protection.
The product supports customization according to the drawing, and can flexibly adjust the size specifications, gasket materials, tail structure, and surface treatment methods to provide more matching fastening solutions for different products.
The pre-installed plastic gasket creates a protective buffer layer that disperses pressure, prevents surface indentations or scratches on delicate housings, isolates contact, and helps reduce vibration transmission.
The guiding section acts as a self-positioning feature that quickly aligns the screw with the pilot hole, minimizing misfits, cross-threading, and assembly deviation in high-speed or restricted automated production lines.
We supply both carbon steel and stainless steel options, paired with machine threads (suitable for tapped metal parts) or self-tapping threads (engineered for plastic and soft composite housings).
Standard options include black oxidation and electroplating, both engineered to enhance anti-corrosion performance while providing a consistent, clean black aesthetic finish.
Yes, full customization is available based on customer engineering drawings, including dimensions, thread pitch, tail geometry, gasket polymers, and surface plating treatments.
It is widely used across consumer electronics, household electrical appliances, precision instruments, and automated industrial machinery where cosmetic integrity and fastening stability are essential.
