The Phillips screws is made of iron and stainless steel. The iron Phillips screws is also called carbon steel screws. The stainless steel Phillips screws has stainless steel SUS201 and stainless steel SUS304, stainless steel SUS316 Phillips screws.
The plating of the Phillips screws generally refers to the plating of the iron Phillips screws. The stainless steel Phillips screws is rarely plated. The Phillips screws plating color is environmentally friendly and non-environmental. The environmental protection plating color has environmentally friendly white zinc, environmentally friendly blue. Zinc, environmentally friendly color zinc, environmentally friendly black zinc, environmentally friendly white nickel, etc., non-environmental white nickel, white zinc, color zinc, black zinc, black nickel, black, blue zinc.
From the beginning of ordering from the Phillips screws wire material into our production screws industry, we must first check the wire diameter of the screws wire and the material of the test screws. Generally, the screws wire diameter is measured by the caliper. The size of the self-order is the same. After detecting these, it is detected during the production process, starting from the head of the screws, determining the head size, head to side, diagonal, cross groove depth, screws tolerance range and so on.
These are all detected with a caliper. In all aspects of the detection of tooth decay, the main thing is whether the thread can pass the pass gauge. Again, the plating measurement problem. After electroplating, is it in line with environmental requirements and can not exceed the time required for salt spray? The tools are environmental testing machines and salt spray testing machines.
