Plow Bolts Flat Head Grey Phosphated Grade 10.9 12.9

Plow bolts feature a countersunk head and square neck to prevent turning when the nut is tightened or removed. They are used in plows and other heavy equipment. 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.

Heat treating makes the plow bolts high strength to Grade 10.9 or 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.
