Hexagon Bolt M8 9/16 Inch Grade 4.8 Galvanized Corrosion-Resistant Industrial Applications
Product Description:
This hexagon bolt is crafted from SS304 stainless steel, which
offers superior resistance to corrosion, rust, and oxidation. SS304
is highly durable in both fresh and saltwater environments, making
it an excellent choice for applications in harsh industrial
settings or outdoor installations. The bolt features an M8 size
with a 9/16-inch thread, offering a secure fit and reliable
fastening in various mechanical assemblies. Graded at 4.8, it
provides sufficient strength for general industrial use, such as in
equipment, machinery, and piping systems. Additionally, the
galvanized finish adds another layer of corrosion protection,
particularly useful in coastal or humid environments where exposure
to water and chemicals is frequent. The bolt is suitable for
industries such as manufacturing, construction, and automotive,
where long-lasting, rust-resistant performance is crucial.
Applications
Galvanising is a surface treatment technique whereby a layer of
zinc is deposited on the surface of a metal, alloy or other
material to provide aesthetic appeal and to prevent rusting.The
main method used is hot-dip galvanising.
Zinc is soluble in acids and alkalis, so it is called an amphoteric
metal.Zinc hardly changes in dry air.In humid air, a dense film of
alkaline zinc carbonate is formed on the surface of zinc.In
containing sulfur dioxide, hydrogen sulfide and marine atmosphere,
zinc corrosion resistance is poor, especially in the high
temperature and high humidity containing organic acid atmosphere,
zinc coating is very easy to be corroded.The standard electrode
potential of zinc is -0.76V, for the steel substrate, zinc coating
belongs to the anodic coating, it is mainly used to prevent the
corrosion of steel, its protective properties of the advantages and
disadvantages of the thickness of the coating is very big.Zinc
coating can significantly improve its protective and decorative
properties after passivation treat
There are two types of galvanising solutions: cyanide plating solutions and cyanide-free plating solutions.Cyanide plating solution is divided into microcyanide, low cyanide, medium cyanide, and high cyanide categories.Cyanide-free plating solutions include alkaline zincate plating solution, ammonium salt plating solution, sulphate plating solution and ammonia-free chloride plating solution.Cyanide zinc plating solution has good even plating ability, and the plating layer obtained is smooth and detailed, which has been used for a long time in the production.However, due to cyanide toxicity, serious environmental pollution, in recent years has tended to use low-cyanide, micro-cyanide, cyanide-free zinc plating solution.
