How to choose combination screws?

The function of combination screws: They have excellent fastening and pressure line capabilities. They are used for high and low voltage contacts, high and low voltage air conditioning wiring, and significant improvements in current, voltage, power, frequency, and performance of electrical appliances. Compared with traditional separate screws, they have advantages such as saving labor, time, etc.

1. First, consider the material requirements for the screws, whether stainless steel or iron is needed.

2. Consider the national specification number requirement for the combination screws. Common specifications include GB9074.8, GB9074.4, GB9074.13, etc.

3. Consider the mechanical strength requirements for the combination screws, such as whether a grade 4.8 or 8.8 is required, and whether the screws need to be hardened.

4. Finally, it is important to note that there are many types of combination screws, such as triple combination screws, hexagon combination screws, cross pan head combination screws, hexagon socket combination screws, stainless steel combination screws, high-strength combination screws, etc. Iron combination screws need to be plated, while stainless steel combination screws do not.
