Summary of information:We have more than ten years of production experience in the screw industry, the main products are: large cap screws GB10...

The advantage of wood screws is that the consolidation ability is stronger than that of nails, and they can be removed and replaced, which is more convenient to use without damaging the wood surface. This is a kind of nail specially designed for wood, and after entering the wood, it will be embedded in it very firmly. If the wood is not damaged, it is impossible to pull it out, and even if it is pulled out forcibly, it will bring out the nearby wood. Another point to note is that the wood screws must be screwed in with a screwdriver. Never knock them in with a hammer, as it will damage the surrounding wood. A screwdriver is a tool for loading and unloading wood screws. The shape matches the groove shape of the wood screw head, and there are two types: one-word and cross-shaped. In addition, there is a special screwdriver installed on the bow drill, which is suitable for loading and unloading large wood screws. Convenient and labor-saving. [2]

In the riveting connection of various structural parts, waterproof lantern rivets have been widely used in riveting environments that require waterproofing. After the riveting parts are riveted, the waterproof structure area of the mandrel and the waterproof structure of the rivet body There is no complete close fit between the areas. In some riveting ranges, the waterproof performance of the rivet is affected. The main reason is that the traditional processing technology of the mandrel and the materials used bring many troubles to the riveting process. is a problem to be solved at present.

④ Screw tooth type A: Self-tapping sharp tail (Japanese standard type 1) sparse AB: Self-tapping sharp tail (Japanese standard type 4) dense; B: Self-tapping flat tail (Japanese standard type 2) sparse; C: Self-tapping Tapping flat tail (the third type of Japanese standard) dense; P: double wire teeth Type triangle teeth CCT: C type triangle teeth PTT: P type triangle teeth STT: S type triangle teeth

The grooved embedded parts are usually connected by bolts, and there are many types of T-bolts used with the grooved embedded parts. position, so that the T-bolt can form a stable connection with the groove-type embedded part, but in the actual installation process, the T-bolt pressed into the groove-type embedded part is prone to loosening problems, so it is difficult to better Fixed in trough embedded parts.

At present, shaft retaining rings are mainly divided into three categories: elastic retaining rings for shafts, flattened wire retaining rings for shafts, and wire retaining rings for shafts. Among them, the spring retaining ring for the shaft is generally installed with circlip pliers, and the flattening wire retaining ring for the shaft and the wire retaining ring for the shaft are generally installed with a sharp screwdriver or needle-nose pliers. The defects and deficiencies of these two methods will be discussed in detail below: First, the above two installation methods require the operator to use a large force to open the retaining ring, which is more laborious; For the installation of the flattened steel wire retaining ring for the shaft and the steel wire retaining ring for the shaft, because the wire retaining ring has low elasticity and has no force point, it is very easy to cause the retaining ring to break or the installation tool to slip during the installation process. Higher skills and experience can be competent for the installation of wire retaining rings.
