Automotive wheel studs car steel lug nuts metric wheel studs
Automotive wheel studs are made of SCM435 with heat treating to reaches grade 10.9/12.9 and then phosphate. The size can be M12/M14/M18/M20/M22/M24/M30/7/8″/1″/1 1/8″. Automotive fasteners are a collection of products that are used in automotive and vehicle assembly. They are usually designed for specific makes/models of vehicles. Ever Hardware provides automotive wheel studs and customizable packaging.
Phosphate coatings are a crystalline conversion coating that is formed on a ferrous metal substrate. The process of Phosphate coating is employed for the purpose of pretreatment prior to coating or painting, increasing corrosion protection and improving friction properties of sliding components. In other instances, phosphate coatings are applied to threaded parts and top coated with oil (P&O) to add anti-galling and rust inhibiting characteristics.
The phosphating process relies on the basic pickling reaction that occurs on the metal substrate when the process solution comes in contact with the metal. The main benefits that phosphating provides are strong adhesion and corrosion protection. Typically, phosphate coatings used on steel parts but can also be used on aluminum. Metal coatings offer both zinc phosphate and manganese phosphate coating. Our phosphate coatings additionally are offered in both dark gray & black.
Heat treating makes the automotive wheel studs high tensile to be Grade 10.9/12.9. Heat treating is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve the desired result such as hardening or softening of a material. Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, normalizing and quenching. It is noteworthy that while the term heat treatment applies only to processes where the heating and cooling are done for the specific purpose of altering properties intentionally, heating and cooling often occur incidentally during other manufacturing processes such as hot forming or welding.
