Is the surface of the extra long socket head cap screws environmentally friendly?
What is environmental protection? Some people do not drive a car, in order to reduce the emissions of car exhaust, travel or bicycle. Some people use plastic bags when shopping, use their own shopping bags and recycle them. In the screw industry, there is also environmental protection, mainly in the plating, then the surface of the extra long socket head cap screws is environmentally friendly?
When the extra long socket head cap screws are plated, the solution required for electroplating is manually configured. Some customers will require that the plated screws do not contain six heavy metals. 6 heavy metals refer to heavy biomarkers such as mercury, cadmium, lead, chromium, vanadium, and metalloids.
If the customer asks that the extra long socket head cap screws are environmentally friendly, then it is necessary to talk to the screw manufacturer. The screw manufacturer will feedback it to the electroplating factory. The electroplating factory will pay attention to the solution when it is configured. Heavy metal materials, such as the electroplated screws are environmentally friendly.
