Sex screws are also known as male and female screws. Male and female screws are a combination of two parts, one male part is also called a screw and one female part is one kind of nut. The screws are used for connecting with the male part locking into the female part. Ever Hardware provides custom-made fasteners 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.
Zinc-Nickel plating is one of the best corrosion-resistant finishes available offering over 5 times the protection of conventional zinc plating and up to 1,500 hours of Neutral Salt Spray test performance. This plating is a combination of a High Nickel Zinc-Nickel alloy (10% – 15% nickel) and some variation of chromate. The most common mixed chromates include Hexavalent Iridescent, Trivalent, or Black Trivalent Chromate. Used to protect steel, cast iron, brass, copper, and other materials, this acidic plating is an environmentally safe option. Hexavalent Chromate has been classified as a human carcinogen by the EPA and OSHA.
