Acorn nut, also referred to as crown hex nut, blind nut, cap nut, domed cap nut, or dome nut (UK), is a nut that has a domed end on one side. When used together with a threaded fastener with an external male thread, the domed end encloses the external thread, either to protect the thread or to protect nearby objects from contact with the thread. In addition, the dome gives a more finished appearance.

Acorn nuts are usually made of brass, steel, stainless steel (low carbon content) or nylon. They 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.

There are standards governing the manufacture of acorn nuts. One is Society of Automotive Engineers (SAE) Standard J483, High and Low Crown (Blind, Acorn) Hex Nuts. Another is Deutsches Institut für Normung (DIN) 1587, Hexagon Domed Cap Nuts.

Hex acorn nut, also known as rivet nut, pull cap, instant pull cap, used in the fastening field of various metal sheet, pipe and other manufacturing industries, widely used in automobiles, aviation, railways, refrigeration, elevators, switches, instruments , the assembly of electromechanical and light industrial products such as furniture and decoration. Developed to solve the shortcomings of thin metal plate, thin tube welding nut and easy to slip internal thread, it does not need to tap internal thread, no need to weld nut, riveting, high efficiency, easy to use


Hex acorn nut type


Flat, small, hexagonal, semi-hexagonal acorn nuts, with through holes, blind holes, knurled and knurled.


Use of hexagonal acorn nut


If the nut of a certain product needs to be installed outside, and the space inside is small, the indenter of the rivet machine cannot be put into the riveting and the method of pumping buds cannot reach the strength requirement, then the riveting and the riveting are not feasible. Must be riveted. Applicable to the field of fastening of various thickness plates and pipes (0.5MM-6MM). The pneumatic or manual rivet gun can be riveted at one time, which is convenient and firm; instead of the traditional welding nut, it can make up for the thin metal plate, the thin tube is welded and melted, and the welded nut is not smooth.


When we choose, or when the customer comes back to purchase the product, the production function is installed. Installation must be achieved through the "press riveting" operation, and you must not use the brute force to enter. Twist slowly along the thread. Therefore, it is very important that the rivet nut passes through the stop gauge. If the material is made of stainless steel, the tail number is indicated by "S". The end face of the nut column is indicated by "C" for the straight tooth. The through hole nut column has a length of 10 mm or less and is full of wire. The hole can be reamed in the hexagonal end face (I type) or the round end face (type II).
