These screws have a sharp point that cuts its own thread as it is screwed into the material These screws have a sharp point that cuts its own thread as it is screwed into the materialtek screw types. Self-tapping screws are commonly used in drywall, furniture assembly, and other applications where pre-drilling is not practical.Applications of Self-Drilling Screws
- Coating and Corrosion Resistance For outdoor or harsh environments, select bolts with the necessary coatings to prevent rust and corrosion.
No matter how big they are, dogs seem to love touching noses with people and other animals. In fact, nose touching is a form of social interaction for dogs, much like shaking hands and hugging humans. But dogs don’t rub their noses with every person or animal. They choose who to rub their noses with. If they don’t like you or don’t know you at all, they won’t touch your nose. However, adult dogs will touch the nose of almost every puppy. They will not only touch the puppy’s nose, but also smell the puppy.
The surface coating of galvanized wire can be seen whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire. High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer, we can generally judge the quality of galvanized wire.
When the barbed rope is installed in different places, the choice of barbed rope column is different. Usually, the barbed rope column we install is cement column, but the use of cement column also has its drawbacks. For example, it’s not so convenient if we install it on a steep hill where transportation is not very convenient. This time can use barbed rope with the composite column to install.

Operating procedures: When using cold galvanized wire, all tools and stacked objects obstructing activities should be removed from the work site and equipment. When pickling, put the wire into the cylinder slowly to prevent acid splashing on the body. When adding acid, it is necessary to pour the acid into the water slowly. It is forbidden to pour the water into the acid to prevent the acid from splashing out. Wear protective glasses when working. Do not push or beat cold galvanized wire and other articles when handling them.
The spray blade has strong adhesion and mechanical strength, and is widely used in the isolation and protection of the boundary of grassland and railway, as well as the protection of garden apartments, units and prisons. The following Haorong for you to introduce the characteristics of spray blade rope.
Large roll galvanized wire is made of low carbon steel wire rod processing, is made of low carbon steel, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling and other surface treatment process processing. Large roll galvanized wire is divided into hot dip galvanized wire and cold galvanized wire (electric galvanized wire). Although galvanized galvanized wire and silver powder paint spray effect appearance is not much different. But the effect is very different, galvanized wire surface is zinc layer, good adhesion, good corrosion resistance.
