Custom Black Pan Head Screw with Plastic Washer and Pilot Tip - China Suppliers & Factory for Stable Fastening
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.
Optimized Head & Protection
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.
Guiding Tail & Assembly Efficiency
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.

Frequently Asked Questions
What are the main design features of this customized combination screw?
This screw features a pan head cross groove structure, pre-installed plastic gaskets, a guiding tail design, and a black surface finish, which balances fastening stability, surface protection, and assembly convenience.
How do the pre-installed plastic gaskets protect the installation surface?
The pre-installed plastic gaskets form a protective buffer layer during fastening. This isolates direct metal contact, reduces vibration transmission, and prevents surface damage or indentation on sensitive components like electronic casings.
What is the advantage of the guiding tail design?
The guiding tail acts as a pre-positioning mechanism that helps align the screw with the installation hole. This minimizes assembly deviation and significantly speeds up manual or automated locking processes in tight spaces.
What materials and finishes are available for this screw?
We offer high-quality carbon steel or stainless steel material options. The surface can be treated with black oxidation or electroplating to enhance corrosion resistance and match aesthetic requirements.
Can these screws be customized to specific drawings?
Yes, we support full customization based on your drawings. You can adjust the size specifications, thread options (machine or self-tapping), gasket materials, tail structures, and surface finishes to suit your product requirements.
