1. Choose the appropriate type

The recommendation for direct sales of precision small screw manufacturers is the most common way for users to choose this accessory. The reason is that there are many classifications of fine and thin screws in terms of types and specifications. Generally, micro screw manufacturers can find suitable purchases without wasting everywhere to find suitable types. energy. Now fine and thin screws have self-tapping and wire types. The biggest difference between the two is whether the tail is top-level, and the top-level tail can be screwed directly into the object without tapping. Users can rely on this feature to most intuitively distinguish whether they meet the requirements when purchasing.

 

2. Choose the appropriate material

Fine slender screws have different material requirements according to different application occasions. For example, some occasions require the use of stainless steel materials, and some require the use of iron materials, so you need to choose according to the requirements. In addition to its own materials, the selection of various types of fine and thin screws also needs to look at the surface material, whether it needs electroplating, whether the electroplating material is environmentally friendly, etc., all require consumers to classify it as a selection condition.

3. Select the appropriate characteristics

Fine and thin screws are also provided with a variety of options according to the environmental characteristics and application characteristics of different operations. For the preparation of work with temperature requirements, heat-resistant and wear-resistant fine and thin screws are introduced; for the work that requires oxidation and corrosion resistance, it is A type that is better represented here has been introduced; but in general, more work is required on the hardness of small screws. However, the area of ​​the fine and thin screw itself is very small. Assuming that you want to tighten the product better, you can ask the manufacturer for hardening. The small size of the product increases the difficulty of hardening, so the user assumes that the hardness is higher and needs to be measured before purchasing.
