Hot galvanized bolts

Galvanized screws, also known as hot galvanized bolts or screws electricity, is placed above 500 degrees screw zinc solution so screws to attach the zinc layer reaches the surface rust and corrosion requirements. Galvanized screws (galvanized screws) usually with galvanized nuts used for outdoor tower, electrical equipment and other wet environments or corrosion demanding applications. Galvanized screws (galvanized bolts) zinc layer thickness between 50-70 microns, for outdoor environments up to 30 years does not rust. With the development of the domestic industry, galvanized screws (galvanized bolts) technology matures, many had the occasion to use ordinary galvanized screws gradually switch galvanized screws (galvanized bolts). After years of galvanized screws (galvanized bolts) sales process, many first-time users to buy, will be mistaken galvanized screws (galvanized bolt) is a special screw thread diameter to be done before galvanizing smaller, it is not true, galvanized screws (galvanized bolt) is placed in ordinary screw attach a high temperature molten zinc zinc layer. Although hot dip galvanized zinc coating thickness increased after the thread diameter but after reaming process with galvanized nuts, does not affect the normal use of galvanized screws. Galvanized screw surface was dark gray, similar to screw with the Dacromet colors, unless a long time under water, or generally for decades will not rust, needs to be noted that in accordance with the hot-dip galvanizing process to avoid screw bolt severe wear, leading to open at the end bolts rust coating. Currently, the market many dealers do not know hot dip galvanizing process, orders will be commissioned by ordinary nut factory galvanized hot dip galvanizing, resulting in galvanized nuts and galvanized screws (galvanized bolts) can not properly fit. Customers are advised to purchase galvanized screws (galvanized bolts) product first ask the seller to provide the best galvanized screws (galvanized bolts) and sample confirmation galvanized nut to prevent the purchase of hot galvanized bolts products can not be used as required. And with the use of galvanized screws usually have galvanized and galvanized flat washers spring washers and other accessories, Haiyan fastener can Fung matching supply! The company produces hot-dip galvanized bolts and nuts look pretty good quality, good service, short delivery flexibility is great standard non-standard parts can be customized to welcome customers to handle it.
