What are precision screws?
The definition of precision screws is simply a small screw. The focus of the screw before is precision, and the so-called precision refers to the relatively high, precise and sharp dongdong. Relatively small dongdong. Compare standard, accurate dongdong. Therefore, the definition of precision screws is relatively simple to understand is more accurate, accurate small screws, referred to as small screws, also known as tiny screws, is a tiny fastener that connects product materials, the shape is small, but the key part of the product material connection can play a key role. Widely used in electronics, electrical, electrical appliances, furniture, mechanical equipment and so on.
Precision screws need to be hardened
If there are hardness requirements for precision screws on product materials, they generally need to be hardened. Because many unhardened precision screws are easy to slip teeth or break easily when using product materials. The most fundamental reason for sliding teeth and broken teeth is that the hardness of precision screws is not enough. Therefore, the precision screws with hardness requirements must be taken to harden them.
Precision screw materials are different
The material of precision screws is iron and stainless steel, and iron precision screws are generally made of iron wire piers, and the materials are low carbon steel, medium carbon steel, and high carbon steel. Screw wire has 1010A, 1018, 10B21, 45 steel, etc. Stainless steel precision screws are generally made of stainless steel screw wire piers. Its materials are stainless steel SUS201, stainless steel SUS304, stainless steel SUS776, stainless steel SUS316, stainless steel SUS404 and so on.
Precision screw plating is different
Electroplating of precision screws generally refers to iron precision screws, stainless steel precision screws generally do not require electroplating, unless required by customers. Precision screw plating color is divided into environmentally friendly and non-environmentally friendly. Non-environmental protection precision screw plating colors are color zinc, white zinc, black zinc, black zinc, white nickel, black nickel, blue zinc and so on. The environmentally friendly precision screw plating colors are environmentally friendly color zinc, environmentally friendly white zinc, environmentally friendly blue zinc, environmentally friendly black zinc, environmentally friendly nickel, environmentally friendly black zinc and so on.
