Product Description

Product Description

 

    The square nut, also known as the square-headed nut or the square-shaped nut, is a common fastening accessory.It has a square shape with four flat surfaces and an internal thread. This shape allows it to be easily installed and removed using common tools,the internal thread matches the external thread of the bolt. By screwing the bolt, two or more components can be fastened together.
 

 

Materials of Square Nut

Carbon steel: It has a relatively low cost and high strength. After appropriate surface treatment, it has relatively good corrosion resistance and is suitable for general mechanical connections and some occasions where the requirements for corrosion resistance are not high
Stainless steel: It has good corrosion resistance, oxidation resistance and high temperature resistance. It is applicable to corrosive environments such as outdoors, humid conditions, acids and alkalis
Alloy: Through the combination of different metal elements, specific properties can be obtained, such as high strength, high hardness, wear resistance, etc., to meet the requirements of some special working conditions.
 

 

Product Parameters

Thread Specifications	Common metric thread specifications include M3, M4, M5, M6, M8, M10, M12, etc.
Nut Height	The heights of square nuts with different specifications also vary. Generally speaking, as the thread diameter increases, the nut height also increases correspondingly.
Opposite Side Width	The opposite side width of a square nut refers to the distance between two opposite sides of the square nut.
Surface treatment	Zinc Plating White Galvanizing Nickel Plating Blackening Treatment
