1. The cap nut and stainless steel hexagonal slotted nut are matched with an open pin and threaded bolt with holes to withstand vibration and alternating loads, which can prevent the nut from loosening and coming out. 2. Cap shaped nuts with inserts, which rely on tightening the nut to tap the internal thread, can provide anti loosening effect and have good elasticity. The purpose of the 3-cap nut is the same as that of the hex nut. Its characteristic is that when assembling and disassembling, a wrench is used to clamp the main nut, which is not easy to slip. However, only an adjustable wrench, a fixed wrench, a dual-purpose wrench (for the opening part), or a specially designed square hole socket wrench can be used for assembly and disassembly. Mostly used on rough and simple components. 4. Cap nuts are suitable for high-strength fasteners, mechanical fasteners, furniture fasteners, vehicle fasteners, machining special-shaped parts, cold heading special-shaped fasteners, double headed foot U-wires, and building decoration fasteners
GB858 stop washers for round nuts are mainly used to prevent loosening of round nuts and are widely used in electrical appliances, elevators, and mechanical fittings, especially when fixing rolling bearings, with significant effects.
In construction engineering, the expansion screw of hexagonal flange sleeve significantly improves installation efficiency and simplifies the installation process. Its design is exquisite, easy to operate, and greatly saves construction time and cost.
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.
It has a hanging function and is used to hang building decorations under cement prefabricated boards, wooden boards, gypsum boards, decorative boards or other board ceilings; The sheep’s eye bolt has a large cross-sectional diameter, long screw and thread lengths, and can withstand high loads when installed on suspended ceilings. It is safe, stable, and not easily loosened.
Connection function: Double headed bolts are mainly used to connect two connected parts, especially suitable for situations where one of the connected parts has a larger thickness or requires a compact connection method. For example, in the fields of mining machinery, bridges, automobiles, motorcycles, boiler steel structures, suspension towers, large-span steel structures, and large buildings, double headed bolts provide reliable fixed connection functions
Hexagonal locking thin nuts are also widely used in the production and manufacturing processes of various mechanical equipment, instruments, household appliances, etc.
1. Characteristic: The wall thickness of the expansion tube is thicker than that of ordinary expansion bolts of the same specifications;The expansion tube is longer than that of ordinary expansion bolts of the same specifications;Several more knurled grooves are added to the expansion tube to increase the tensile strength;The size of the screw head is larger than that of the ordinary expansion bolt head;The matching washer is a large washer. 2. Requirements: The drill bit required for drilling should be 6 sizes larger than the product size. 3. Application:Elevator expansion anchors are a type of fastener specially used for elevator installation. They are usually made of high-quality steel and have strong seismic resistance and gripping power.
DIN125 Flat Washer are mainly used to connect two objects, fill gaps, and play a role in sealing, supporting, and fastening. It is widely used in various mechanical equipment, pipeline systems and other connections, with good sealing performance and mechanical strength.
It is used to support structural steel columns, lamp posts, heavy equipment, highway signs, and many other applications. Its hook provides resistance, preventing it from pulling out of the concrete foundation when force is applied. Stainless steel bent anchor bolts are used to secure embedded plates, signage structures, columns, and many other structural objects to concrete.
1.DIN6923 hexagon flange nut and general hexagon nut compared with the size and thread specifications are basically the same, but more than the hexagon nut with one ring flange, equivalent to the washer and nut are integrated, and there is a ring of non-slip tooth grain on the flange surface, also known as tooth flange nut. 2. Widely used : hexagon flange nuts mainly play a role in increasing the contact surface with the workpiece, mostly used in pipelines, fasteners and some stamping parts and casting parts. The flange face of DIN6923 flange nut itself has the function of anti-slip and stop, and it does not need to add flat pad and spring pad when assembling, which is more convenient to use
DIN582 lifting ring nuts are mainly used to connect chains and steel wire ropes, and can also be used for lightweight lifting. The hanging ring nut refers to a component that is screwed together with a bolt or screw to provide a fastening effect, and is a necessary component for all production and manufacturing machinery.
Drop in anchors are mainly used for situations where the embedded depth is shallow, by tightening the nut to expand the expansion tube and achieve fastening. This type of screw is suitable for concrete substrates, easy to install, and has high bearing capacity.
The T-bolt can be directly placed into the aluminum profile groove, and it can automatically position and lock during installation. It is often used in conjunction with flange nuts and is a standard matching connector for installing corner pieces. It can be selected and used according to the width of the profile groove and different series of profiles.
1. Core type expansion bolt is a common connector, widely used in construction, bridge, mechanical equipment and other fields. It has the advantages of simple installation, high bearing capacity, good seismic performance and so on 2 Core expansion is mainly used in buildings to install suspended ceilings, walls, steel structures, wire trough pipe supports, air pipes, door and window frames and other places that need to be fixed. The expansion anchor has the characteristics of simple installation, reliable, strong bearing capacity and wide application range. At the same time, it can also adjust the distance between the fixed object and the substrate by tightening the screws.
1.The good expansion curve design greatly enhances the anchoring force of the anchor bolt, and the edge of the tube head can effectively prevent the expansion screw from entering the deep inside the hole due to drilling too deep 2. Widely used :Concrete, natural dense stone, solid brick, solid gray sand brick light concrete, hollow concrete brick, etc.;
