Screw is one of the common fasteners, and there are many types of screws, including drill tail screws and self tapping screws. The tail of the drill tail screw is in the shape of a drill tail or pointed tail, and does not require auxiliary processing. It can be directly drilled, tapped, and locked on the setting material and foundation material, greatly saving construction time. Compared to ordinary screws, it has high tensile strength and holding force, and will not loosen even after being combined for a long time. It is easy to use safe drilling and tapping to complete the operation in one go. Especially in the integration of construction, architecture, residential and other places, self tapping and self drilling screws are the best economical fasteners in te...
In the fastener industry, the role of washers goes far beyond the single function of protecting the surface of connectors from scratches caused by nuts. There are various types of gaskets, including flat gaskets, spring gaskets, anti loosening gaskets, and special purpose gaskets such as sealing gaskets. Each type of gasket plays an indispensable role in its specific application scenario. Firstly, as the supporting surface for threaded connections, the bearing capacity of the gasket cannot be ignored. In practical applications, due to excessive positional tolerance or hole size issues, sometimes the supporting surface of bolts or nuts cannot fully cover the holes on the connect...
Anchor, seemingly ordinary building accessories, actually play an indispensable role in modern architecture and daily life. They have become a bridge connecting stability and safety with their unique fixing mechanism and wide application fields. Anchors, as the name suggests, achieve a strong fixing effect through the frictional force generated by expansion. Their working principle is simple and efficient, that is, after the screw is inserted into the preset hole, the metal sleeve of the screw will expand and tightly fit the hole wall, thereby firmly fixing the bracket, equipment or other heavy objects. In the field of architecture, the application of anchors is almost ubiquitous, from the stable installation of large mechani...
