The use of stainless steel hex screws

Stainless steel hex bolts also known as stainless steel hex screws, or referred to as stainless steel hex bolts. Its material is stainless steel, which is a hexagonal bolt made of stainless steel screw wire. stainless steel hex screws have stainless steel 201, stainless steel 304, stainless steel 316 and so on. According to the different stainless steel materials, the market pricing is also different, the better the material, the higher the price.

Stainless steel hex screws are commonly used in the series of stainless steel fasteners. They are used in conjunction with nuts and are used in places where the product has higher anti-corrosion requirements and surface finish requirements. Stainless steel hex screws generally have full teeth and half teeth. The products of the half-tooth are divided into thick-rod half-tooth and thin-rod half-tooth. Production of stainless steel hex screw material commonly used have SUS304 and SUS316 two. Most of the circulating stainless steel hex screws are full teeth

The stainless steel outer hexagonal screw used in automobiles refers to the hexagonal bolt made of stainless steel screw wire, and it is made of stainless steel 201, 304, 316 and other materials. It is mainly used in auto parts. In addition, it also uses Torx screws, self-tapping screws, etc. The screws selected according to the requirements of the product are different, and nuts and bolts on some accessories are also used.

Stainless steel screws in the very wet conditions, the sun every day, the wind and rain. After a long time, it will definitely rust.

1. The attachment of dust or heterogeneous metal particles, in the humid air, the attachment and the condensed water of the stainless steel screw connect the two into a micro-battery, causing an electrochemical reaction, and the protective film is damaged, which is called electrochemical corrosion.

2, in the polluted air (such as containing a large amount of sulfide, carbon oxide, nitrogen oxide atmosphere), the case of condensed water, the formation of sulfuric acid, nitric acid, acetic acid liquid point, causing chemical corrosion.

3, stainless steel surface adhesion containing acid, alkali, salt substances (such as the decoration of the wall of alkaline water, lime water splash), causing local corrosion.

Stainless steel hexagon screws to solve the way:

Step: First, use stainless steel hexagon screw cleaning agent to remove oil, rust and various substances on the surface. After three minutes of treatment, the workpiece is bright as new, which can restore the original luster of the workpiece, does not hurt the substrate of the workpiece, and has short antirust performance. It is safe and environmentally friendly to use, does not volatilize and does not leave any residue.

Step 2: Stainless steel passivation solution can be used for rust prevention of stainless steel hexagonal screws. The operation is simple and only needs to be used at normal temperature with a plastic groove. The passivation time is 1 hour. After passivation, the size and appearance of the workpiece will not be changed. At the same time, a passivation film is formed on the surface, which can prevent the workpiece from rusting again. After passivation, the workpiece has a bright and clean surface and can prolong the service life of stainless steel screws.
