The function of the hot-dip galvanized pin is to locate and fix the parts. There are generally two types: cylindrical and conical. Hot dip galvanized pins are usually installed by two methods: pressing method or soft metal tapping method. Pins are usually conical, pointed or peaked wood, small metal nails, used to nail or fasten (boards, tiles, soles, uppers, furniture molds and components) or repair holes.

In short, the hot-dip galvanized pin is a connecting piece, sometimes it also plays a role in positioning and fixing. According to the nature of connection, it can be divided into rigid pin and elastic pin. The rigid pin cannot move when connected, while the elastic pin leaves a certain range of relative motion. Pay attention to the bearing capacity when connecting pins. Because the section of the pin is relatively small, it is not suitable for use when the transmission load is large.

There are many types of hot-dip galvanized pins, and each type has different specifications. However, no matter which one is, it is very convenient to disassemble and assemble, and the positioning accuracy is also very high. No matter how many times it is disassembled, it can be properly installed in its original position. The removal of the hot-dip galvanized pin is also very simple, as long as there are tools to remove the pin, it is easy to remove it.

1. Appearance: the surface is smooth and flat, coated with antirust oil, and the chamfer is smooth without burrs. The surface shall be free of black skin, cracks, folds and inclusions.

2. Dimension: inspect according to drawings or sealed samples.

3. Surface roughness: the surface roughness shall not be greater than 3.2.

4. Hardness: inspect according to drawing requirements or sealed samples.

5. Thread: the thread end of the shaft shall be screwed in with a nut with appropriate tightness.

6. Rust proof test: no rust when tested with 10% salt water.
