Featurers of high strength hot dip galvanized bolts High strength hot dip galvanized bolt is a typical anodic coating, which is mainly used to improve the corrosion resistance of the substrate. Because of its thin coating thickness, it is mainly used for surface anti-corrosion protection under general environmental conditions. After chromate passivation treatment, the corrosion [...]
Application advantages of high strength hot dip galvanized bolt High strength hot-dip galvanized bolts are widely used. Compared with other paint coatings, the cost of hot-dip galvanized bolts is very low, but they can also play the role of rust prevention and corrosion prevention, so they are welcomed by manufacturers and enterprises. Application advantages of [...]
High Strength Blackened Bolt Blackening process is blackening during tempering in heat treatment process. Different blackening process will directly affect the quality of screws. Attention should be paid to the following problems in the treatment process of high strength blackened bolt: Acid and alkali substances are strictly prohibited, which will damage the film-forming function of [...]
How to reduce the rust of high strength hot dip galvanized bolts? What measures can be taken to reduce the rust probability of high strength hot dip galvanized bolts? High strength hot-dip galvanized bolts in the production of processing surface, hot-dip galvanizing process will be carried out on the surface, which can enhance the anti [...]
Anti corrosion treatment method of hexagon socket bolts surface In the production of hexagon socket bolts, one of the most important links is to carry out anti-corrosion treatment on the surface. You may ask "how to carry out anti-corrosion treatment?" in fact, different corrosion conditions lead to different anti-corrosion treatment methods. Today, we will briefly [...]
Heat treated high strength fastener should be quenched and tempered according to the technical requirements. The purpose of heat treatment and tempering is to improve the comprehensive mechanical properties of fasteners to meet the specified tensile strength and yield ratio of products. Heat treatment process has a vital impact on high-strength fasteners, especially its internal [...]
There are three kinds of materials for high strength hexagon bolts, as follows: (1) carbon steel. Generally, hexagonal bolt manufacturers distinguish low carbon steel, medium carbon steel, high carbon steel and alloy steel according to carbon content in carbon steel. 1. Low carbon steel C% ≤ 0.25% is usually called A3 steel in China. It [...]
High quality hexagon bolts are mainly used to fix pipes, pipelines and other pipe diameter products. The internal radian of hexagon bolt is very important, and its radian is required to be natural and consistent with the radian of the installed pipe diameter, which is close to and wrap the pipe diameter to be fixed. [...]
The advantage of high strength Dacromet bolt is due to the development of Dacromet, which has become a necessary technical requirement in some workplaces. The main reasons are as follows: 1. Electroplating not only pollutes the air, land and water, but also does great harm to operators. The state has repeatedly declared that it is [...]

The countersunk hexagon bolt is often used in machinery, which has the advantages of easy fastening, disassembly and not easy to slide angle. The hexagon wrench is generally a 90 ° bend, one end of the bend is long and the other side is short. When the short side is used to bolt, holding the [...]
Hot dip galvanized hexagon bolts are divided into ordinary and reamed ones. According to the head shape: there are hexagonal head, round head, square head, sink head and so on. The hexagon is the most commonly used. The countersunk head of hot-dip galvanized bolt is generally used in the place where connection is required. The [...]
The following problems should be paid attention to in the construction of high strength bolts: (1) Surface rust, oil stain, burr and weld bead on bolt hole wall shall be cleaned. (2) After treatment, the contact friction surface shall meet the requirements of anti scratch coefficient. The high-strength bolts used shall be matched with nuts [...]
