| 1. Improve connection tightness: The internal locking washer uses its locking teeth to fill the gap between it and the connecting body by applying pressure during equipment assembly, thereby achieving fastening and locking effects. This design can effectively reduce the risk of connection failure, improve equipment efficiency, and reduce maintenance costs 2. Preventing loosening: The internal tooth locking washer will generate a backward thrust after tightening, which can prevent the nut or bolt from loosening and ensure the stability of the connection. This is particularly important for equipment operating under vibration or dynamic load conditions 3. Load dispersion: Internal tooth locking washers can increase the contact area between connecting components, thereby dispersing the load force. This not only improves the load-bearing capacity of the connecting parts, but also provides some protection for the connecting components, avoiding damage caused by local stress concentration |

1.The biggest feature of drywall screws in appearance is the trumpet head shape. They are divided into double-line fine-thread drywall screws and single-line coarse-thread drywall screws. The biggest difference between the two is that the former has double threads. 2. Easy installation: Drywall screws are easily driven through the drywall sheet and secured to the frame by hammering it directly into place without the need for pre-drilled holes. 3.High Strength: Drywall screws are made of metal and have high strength and compression resistance. 4. Wide application: Drywall screws are usually used for interior decoration to install various gypsum boards, ceilings, lightweight partitions, light steel keels, etc.
Solar panel aluminum middle clamps are designed for 30-50 mm solar modules with frames. The design is accurate. The middle clamp provides a solid connection between the panels and secures the panels to the guide rail.
DIN6921 flange bolts are widely used in various mechanical equipment and engineering structures, especially in application scenarios facing high tension or strong shear working conditions. Its design features include high strength, high precision, corrosion resistance, and mature technology, ensuring the safety and quality of the connection.
Hollow wall anchor bolts, also known as hollow wall anchors or hollow expansion screws, are mainly used in hollow walls, gypsum boards, fiberboards, plastic boards, wooden boards and other walls. They are light load anchor bolts. The heads and nuts at both ends are of two types: “welded” and “integrated”. They can be directly installed with an electric screwdriver or pulled with special tools. Installation method: 1. The teeth on the head of the casing can be embedded in the hollow substrate, which can effectively prevent the casing from rotating in the hole during installation. 2. After installation, the expansion arm is opened behind the hollow substrate to form a large radius and large area of contact, providing a reliable anchoring effect. 3. The matching screws can be easily removed, and the mounting parts can be repeatedly disassembled and assembled without affecting the anchoring effect. 4. Ordinary flat-blade or cross screwdrivers can be used for installation. If special installation tools are used, it can be more suitable for large-scale professional use occasions.
GB854 Tab Washers With Long Tab is mainly used to prevent bolts or nuts from loosening in vibration environments, ensuring the stability of the connection.

How to use:The new American-style core expansion nail only needs to make a 6mm hole on the ground or wall. The depth is the same as that of the expansion nail. Put the expansion nail into the hole and hammer the head of the expansion nail with a hammer. The tail of the core nail will expand during the hammering process. The nail will be tightly stuck in the casing and will not be pulled out. The use process saves time and effort, and is more beautiful than the pull-out screw. ① Drill a hole in the wall according to the size requirements; ②Insert the expansion screw through the fixed object into the hole; ③Hit the iron nail to expand the inside.
