Copper nuts are made of various embossed wires (usually lead brass, such as H59, 3604, 3602). The embedded knurled copper nuts that we encounter on a daily basis are machined with precision automatic lathes. The following editor will show you how many types of copper nuts are there? What are the contents of the standard, welcome to read!
 
How many types of copper nuts are there?
 
Embedded nut
 
Copper nuts are made of various embossed wires (usually lead brass, such as H59.3604.3602). The embedded knurled copper nuts we touch every day are made by precision automatic lathes. The reference standard for embedded knurled copper nuts comes from the national standard GB/T809.
 
Knurled copper nut
 
Knurled copper nuts are mainly used for hardware springs, special-shaped springs, craft gift springs, battery springs, spring antennas, key rings, phosphor bronze springs, CNC automatic lathe cutting parts (copper car parts, iron car parts, aluminum car parts), Metal stamping parts, electronic hardware, iron shafts, single flower shafts, multi-flower shafts, iron pins, non-standard screws and nuts, connectors, fasteners, wire forming (metal wire business card holder, model aircraft landing gear, S hook, R type bolt, triangle buckle, D type buckle)
 
Injection-molded copper nut
 
Injection-molded copper nuts can be understood as inlaid copper nuts or inlaid copper nuts. At present, injection-molded copper nuts on the market are different and have different uses.

What are the standards for copper nuts?
 
1. Nuts are nuts that are tightened with bolts or screws, and are used to fasten parts. One of the originals that all manufacturing machinery must use. Nuts are available in a wide variety, including national, British, American and Japanese standards. Nuts are classified into carbon steel, high strength, stainless steel and plastic steel according to different materials. According to product attributes, different national standard numbers are divided into ordinary, non-standard, (old) national standard, new national standard, American system, British system, and German standard. Threads of different sizes are divided into different specifications. General national standard. German standards are represented by M (such as M8.M16), and American standards are represented by fractions or # (such as 8#.10#.1/4.3/8).
 
2. Nuts are parts that tightly connect mechanical equipment. It can only be connected together by means of internal threads, nuts and screws of the same size. For example, M4-0.7 nuts can only be matched with M4-0.7 screws (in nuts, M4 refers to the inner diameter of the nut is about 4mm, and 0.7 refers to the distance between the two thread teeth is about 0.7mm); beauty products are also in this way. For example, a 1/4-20 nut will only mate with a 1/4-20 screw (a 1/4-finger nut has an inside diameter of about 0.25 inches, and a 20-finger has 20 teeth per inch).
