Plough Bolts Metric Plow Bolts Grade 8 Flat Head Plow Bolts

Plough bolts are also known as plow bolts. 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.

Heat treating makes the plough 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. 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.

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.
