Metal Nut

Metal nut is the nut, screwed with the screw or screw together to play the role of fastening parts, all manufacturing machinery must use a component. A wide variety of nuts, we have common GB, German standard, British standard, American standard, the standard of the nut.

Nuts according to the different materials, divided into carbon steel, high strength, stainless steel, steel and other major types. According to the product attributes corresponding to different national standard number is divided into ordinary, non-standard, (old) GB, the new national standard, US, British, German standard. Different sizes, different threads are divided into different specifications. (Such as M8, M16), the United States, the British system with the score or # that specifications (such as 8 #, 10 #, 1/4, 3/8)
2, the nut is the mechanical equipment connected to the parts, through the inside of the thread, the same specifications of nuts and screws to connect together, for example, M4-0.7 nut can only be used with M4-0.7 screw (in Nuts, M4 refers to the nut diameter of about 4mm, 0.
7 refers to the distance between the two thread teeth 0.7mm); US-made products are the same, such as 1 / 4-20 nuts can only be with 1 / 4-20 of the screw with (1/4 refers to the nut diameter of about 0 .25 inches, 20 fingers in each inch, there are 20 teeth).
DISC-LOCK Lock nut is composed of two parts, each part has a staggered cam, because the internal wedge design slope angle is greater than the bolt
Nut angle, this combination will be tightly bite into a whole, when there is vibration, DISC-LOCK loose nuts raised part of the convex parts of each other, resulting in lifting tension, so as to achieve the perfect anti-loose effect.
Folding embedded nut
Using a variety of embossed wire production (usually lead brass, such as H59,3604,3602) made of copper nut. Our daily access to the embedded rosette copper nuts are made of precision automatic lathe processing. The reference standard for embedded rosette copper nut comes from GB / T809.
The main operation of the embedded rosette copper nut is injection molding, after heating into the plastic parts inside or direct mold injection, if the use of mold injection, PA / NYLOY / PET melting point are above 200 ° C, embedded nut was hot After the plastic parts of the temperature quickly become high, after injection molding, the rapid cooling of the plastic body crystal hardening, if the embedded nut temperature is still at high temperatures, it may fall to the copper nut and plastic parts of the place began to loose or cracks The So in the injection of nuts are used in the copper nut instead of carbon steel nut.
There are two ways of forming the outer copper thread of the embedded copper nut. One kind is the production of the raw material of copper. After the flower is formed on the upper equipment, the general pattern of the flower pattern is straight and the other is Light round copper material directly in the production process while tapping the edge of embossing, this processing can produce some non-standard size of the rolling copper nut, embedded copper nut embossed shape can be selected with the user, such as textured, Eight words embossed, embossed characters and other rolling patterns.
Stainless steel nut series
