Dacromet Coated Bolts Grade 8 Pan Torx Head Dacrotized Screws Supplier

Dacromet coated bolts are comprised mainly of overlapping zinc and aluminum flake in an inorganic binder. 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. Ever Hardware provides custom-made fasteners and customizable packaging.
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

Torx screws are commonly found on automobiles, motorcycles, bicycle brake systems (disc brakes), hard disk drives, computer systems and consumer electronics. Initially, they were sometimes used in applications requiring tamper resistance, since the drive systems and screwdrivers were not widely available; as drivers became more common, tamper-resistant variants, as described below, were developed. Torx screws are also becoming increasingly popular in construction industries.

Heat treating makes the dacromet coated bolts high tensile. 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.
