Hot Dip Galvanized High Corrosion grade 4.8/8.8 Hex head bolts , galvanized bolts


Description:


This is Jiaxing Haina ,welcome to visti our company website.

Hex head bolts, commonly called hex head cap screws, are bolts with a hexagonal or six sided head,also called hexagon head bolts, hex head cap bolts, allen bolts or machine bolts and so on, are a very common choice when it comes to construction and repair. A common feature on a hex cap screw is a washer surface directly under the head which creates a better seal.


As a result of the action of zinc sacrificial anode protection with steel base, can greatly prolong the service life of steel workpieces.So early people take the lead and zinc processing of galvanized as a common long-term anticorrosion measures, steel galvanized become the most important use of zinc.

Abroad have produced many kinds of series and the brand of hot galvanizing alloy, its performance is superior to the traditional hot dip galvanized (Calvanized).Early use of Galvalum alloy (2 n - 55% of Al and Al 2 n - 55% - 55% Si) has excellent corrosion resistance.The recent development of Galfan alloys n Al - 5% - 5% of rare earth (2) low melting point, good liquidity, can better protect steel exposed edges, in use in the bad water 30% ~ 500% higher than that of traditional galvanized steel corrosion resistance, corrosion of the addition of rare earth can prevent to produce tiny points, also has the ductility and plasticity, spot welding and deep drawing performance and shading performance improvement, etc.


Because of its fully threaded body, this is used in many of applications such as in the vehicle repair industry when attaching a motor to a machinery. Different form a screw TYPE, hex bolts are designed to be inserted through holes in assembled parts, because these do not have their own mating internal threads and are tightened by torqueing the head. Hex bolts are not pointed where hex bolt have a chamfered point to protect the first thread from damage and to faciliate entry into an internally threaded part such as a nut or tapped holes.Also, these can be used with pulley to adjust the belt tension.


A Chinese factory production of zinc - aluminium - lead alloy, used for steel hot dip plating, is on the basis of zinc, add the right amount of aluminum and lead in lead and zinc production line in the power of 540 kw within 20 t induction furnace melting system.The chemical composition of the materials (%) as follows:


Electrolytic zincZn >99. 99,Ph0. 005,Cu <0. 001.Cd <0.002.Fe<0.003;
AluminumAl >99. 99;
Electrolytic leadPstrong > 99. 99. Cu < 0.0004, Bi < 0.003.

Application:


Also known as hot dip galvanized, hot dip galvanized he is under the high temperature melt, the zinc ingots in add a few auxiliary material, and then immerse metal structure in the zinc bath, attached to a layer of zinc layer on metal components.Hot dip galvanized anti-corrosion advantage lies in his ability, good adhesion and hardness of the galvanized layer.

This product is widely used in machinery and transport, architecture, hot industry, light industry, electricity, etc
