Expansion anchor
The expansion anchor bolt consists of several main parts: the ring cylinder, gasket, and nut. When in use, make a hole in the wall and insert the expansion bolt into the hole. When tightening the bolt, the ring cylinder will be squeezed and stretched open, and will be stuck in the hole to provide a fixing effect.
Expansion anchor bolts are widely used in the field of construction to secure supports/hangers/brackets or equipment to walls, floors, and columns. Its advantages include easy installation, good fixing effect, and the ability to withstand large tensile and shear forces, making it suitable for a variety of materials and structures. -

M3 M4 M5 M6 M8 M10 M12 M14 M16 DIN6926 Stainless Steel 304 Nylock Nut Flange Nylon Insert Locking Nuts
Flange anti loosening nut is a type of nut with special structure and performance. The following is a detailed introduction for you:
characteristic:
- Flange design: There is a wider flange at the bottom of the nut, which not only increases the contact area between the nut and the connecting piece, reduces the pressure per unit area, thereby reducing damage to the surface of the connecting piece, but also helps to improve the bearing capacity and stability of the nut.
- Excellent anti loosening performance: Through various anti loosening mechanisms, such as adding special coatings on threads, using deformed threads, embedding elastic materials (such as nylon rings), etc., it can effectively resist loosening caused by factors such as vibration, impact, and temperature changes, ensuring the reliability and safety of the connection.
- High strength: usually made of high-strength materials, capable of withstanding large loads.

Washer
Spring washer’ usually refers to a spring washer.
It is a commonly used anti loosening component in fastening connectors. By its own elastic deformation, a continuous pressure is applied to the threaded connection after tightening the bolt or nut, thereby increasing friction and preventing loosening.
There are various types of elastic pads, including standard, light, heavy, etc. Different types have differences in elasticity, size, etc., to adapt to different working conditions and connection requirements.

Factory Custom Yellow Zinc Plated Carbon Steel Hex Flange Head Bolt M6 M8 M10
A flange bolt is a type of bolt with a flange on the head.
Its characteristics include:
- Increase contact area: The presence of flanges increases the contact area between bolts and connectors, disperses pressure, and reduces damage to the surface of connectors.
- Improve anti loosening performance: Compared with ordinary bolts, flange bolts have better anti loosening effect in vibration environments.
- Easy installation: The edges of the flange are usually chamfered or rounded, making it easy to install and position.

Carbon Steel Grade 4.8 8.8 10.9 Zinc Plated Rail Fish Bolt Plate And Nut Fishtail Fastener For The Tower Railway
Fish tail bolt, also known as fish tail bolt or fish tail screw, is a commonly used fastener for railway track connections.
Its shape resembles a fish tail, hence its name. Fish tail plugs are usually made of high-strength steel, which has good tensile strength and fatigue resistance.
Its main function is to tightly connect the steel rails and sleepers together, ensuring the stability and safety of the railway track. The specifications and dimensions of fish tail bolts may vary depending on the type of steel rail and sleeper.
When installing and using fishtail bolts, it is necessary to strictly follow relevant standards and specifications to ensure their fastening effect and the safety and reliability of railway operation.
