Acorn Lug Nuts Caps Car Wheel Lock Nuts Tuner Wheel Nuts

Acorn lug nuts are a type of fastener that gets its name from its shape. Acorn nut is its common name and it is also called a crown hex nut, blind nut, cap nut, or domed cap nut. It is a nut that has a domed top to cover the threads. This is to prevent contact with the external thread to protect the threads or protect other things the threads would rub against. In addition, the dome gives a more finished appearance. It is usually made of brass, steel, stainless steel (low carbon content), or nylon. It can also be chrome-plated and given a mirror finish.
There are two types of acorn nuts. One is low, or the standard acorn nut. The other is the high acorn nut. The high acorn nut is wider and higher and will protect extra long studs. There are also self-locking acorn nuts that have distorted threads in the hex area to create a tight friction fit to prevent the nut from vibrating loose.

The nut made of SCM435 with heat treating to reaches grade 10.9/12.9 and then galvanizing. The size can be M14/M18/M19/M20/M22/M24/M27/M28/M30/5/8″/3/4″/7/8″/1″/1 1/8″. Ever Hardware provides custom-made fasteners and customizable packaging.

Heat treating makes the acorn lug nuts 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.
