Rock Support Steel Nut Tighten Role


Rock Support Steel Nut Tighten role

Nut is nut and bolt or screw fastening screw together to the function of parts, all production machinery must use a components according to different materials, the divided into carbon steel, stainless steel, non-ferrous metals such as copper and so on several big types.

Nut is closely connected parts machinery and equipment, through the inside of the thread, the same specification nuts and bolts to connect together, for example, the M4 - P0.7 nut only with M4 bolts - P0.7 series connection (in the nut, the M4 refers to the nut inside diameter is about 4 mm, 0.7 refers to the distance between the two thread is 0.7 mm). U.s.-made products are the same, for example, a quarter - 20 nut only with 1/4-20 screw (1/4 refers to the nut inside diameter is 0.25 inches, about 20 every inch, there are 20 teeth).

The disc-lock anti-loose nut is made up of two parts.

Each part has staggered CAM, due to internal wedge Angle design of slope Angle is greater than the bolt nut, the combined tightly bite into a whole, when the vibration occurs, DISC - LOCK raised portion are performed.the locknut, raising tension, so as to achieve the perfect effect of locking.
