Self-drilling self-tapping screws have many different head types, and many people do not know that the head types are different, and their roles are also different. There are several commonly used hea

The tail-drilling screw uses the tail-drilling at the tail to chip off the tapped object (steel plate, aluminum plate, etc.), then tap the thread directly, and then tighten it. This seemingly simple t

In addition to being used in some engineering projects, self-drilling screws are also suitable for home decoration. Compared with other screws, the self-drilling screw has the characteristics of direc

For the fracture of ferrous screws, it is very easy to encounter in practical applications. However, the fracture of stainless steel screws is rarely seen. The reason is that the material of the stain

A few days ago, the Disco metal surface treatment technology was introduced. Here I will introduce another metal surface treatment technology-Dacromet.Dacromet is a relatively new type of corrosion-re

Slotted and cross-slotted screws can be seen everywhere in life. In contrast, the inner and outer hexagons are also very common. In addition, there are many other styles of drive slots.Briefly talk ab

1. Electro-galvanizedElectro-galvanizing is the most commonly used coating for commercial fasteners. It is cheaper: it looks good, and it can be black or army green. However, its anti-corrosion perfor

With the continuous update and iteration of modern industrial technology, the fields involved in mechanized production are becoming more and more extensive. In the past, operations that were absolutel

Concrete self-tapping anchors are still vacant in the domestic market. Compared with the foreign penetration rate, domestic concrete anchors are still skeptical. This is understandable. After all, the

Compared with traditional expansion anchors, concrete self-tapping anchors not only have advantages in performance, but also have obvious gaps in construction efficiency. Concrete self-tapping anchors

Like expansion anchors, rear expansion anchors are widely used for installation and fastening in concrete structures, but rear expansion anchors are more cumbersome in terms of installation efficiency
