Summary of information:We have more than ten years of production experience in the screw industry. The main products are: H59 injection molded ...

Screws are very small screws used for indispensable industrial necessities in daily life, such as cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; large screws are used for engineering, construction, and bridges; Transportation equipment, airplanes, trams, automobiles, etc. use large and small screws together. At present, in the machine assembly production line, when the flat washers, spring washers and screws are matched during the screw assembly process, the flat washers, spring washers and screws are easy to fall into the product due to their small size, resulting in low screw matching efficiency. If there are flat washers, spring washers, screws, etc. that fall into the product and are not found in time and left inside the product, it may cause damage to the machine structure, and even cause casualties in serious cases.

Drilling screw is a new invention of people in recent years. A screw is a common term for fasteners, an everyday colloquial language. The tail of the drill tail screw is in the shape of a drill tail or a pointed tail, and no auxiliary processing is required. Drilling, tapping and locking can be directly carried out on the setting material and basic material, which greatly saves construction time. Compared with ordinary screws, its toughness and pull-out force and maintenance force are high, and it will not loosen for a long time after combination. It is easy to use safe drilling and tapping in one operation. Drill tail screw Drill tail screw use: It is a kind of screw, mainly used in the fixing of color steel tiles of steel structures, and can also be used for thin plate fixing of simple buildings. It cannot be used for metal-to-metal bonding. Materials and models The materials are iron and stainless steel, of which stainless steel is divided into various materials. Models are: Φ4.2/ Φ4.8/ Φ5.5/ Φ6.3mm, the specific length can be agreed upon request. According to the different drill tails, it can be divided into: round head rice / cross / plum blossom, countersunk head (flat head) / rice seed / cross / plum blossom, hexagonal washer, round head washer (big flat head), horn head, etc.

A nut provided by Yueluo. The nut is in the shape of a casing and is provided with a threaded section. One end of the threaded section is provided with a protrusion on the wall of the hole. The nominal size of the segment or the distance from the rear end of the lug to the hole core in the screw-in direction is smaller than the nominal size of the threaded segment.

At present, injection molding screws are widely used in various electronic and automotive components, including a body, the middle of which is provided with a through hole 3, the body head 1 has a hexagonal cross-section, and the tail 2 is provided with screw teeth. When in use, the middle through hole 3 of the body will first put the wire harness, and then fix it by injection molding from the head I, and the threads of the tail 7 should be connected and installed with other components. Because the head I of the main body is hexagonal, the torque provided after injection molding is insufficient. Therefore, after the external thread is installed and connected with other components, the head is prone to slip, the installation is not reliable, and there is no push-pull force, resulting in product failure and increased safety hazards.

Usually, the pumped storage unit adjusts the opening of the guide vane through the movable guide vane to control the power generation output and the pumping head of the unit. The torque of the guide vane rotation depends on the relay to act on the control ring, and the torque is transmitted to the guide vane rotating shaft through the connecting rod and the arm. The torque transmission between the crank arm and the rotating shaft all acts on the pin located between them. When the unit is overhauled, it is necessary to remove the pin between the arm and the rotating shaft of the guide vane in advance when it comes to the replacement of the guide vane. However, due to the special position of the pin and the limited inspection space, the conventional method is not only time-consuming and laborious, but also has the risk of damaging the pin. Maintenance work brings inconvenience.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: thin head hexagon socket bolts, supply hexagon flange nuts, backrest pin rubber rings, set cup head nuts and other products, we can provide you with suitable products Your fastener solution.
