Automotive fasteners automotive nuts and bolts hardware

Automotive fasteners are made of SCM435 with heat treating to reaches grade 10.9/12.9 and then galvanizing. The total length can be 89/100/102/111/114/115/120/128mm. Ever Hardware provides automotive fasteners and customizable packaging.

Dacromet is the leading inorganic coating specified by automotive companies worldwide and is a proven coating system in many industries. A water-based, VOC compliant coating, dacromet is comprised mainly of overlapping zinc and aluminum flake in an inorganic binder.
Four Way Corrosion Protection
 Barrier Protection: Overlapping zinc and aluminum flakes provide an excellent barrier between the steel substrate and the corrosive media
 Galvanic Action: Zinc corrodes to protect steel
 Passivation: Metal oxides slow down the corrosion reaction of zinc and steel to provide 3 times greater corrosion protection than pure zinc
 Self-Repairing: Zinc oxides and carbonates migrate to the damaged area of the coating to actively repair the coating and restore barrier protection

Heat treating makes the automotive fasteners 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.
