Service HotlineGuangdong Yueluo Hardware Industry Co., Ltd. relates to a connecting piece, especially a Torontowood screw used for fixing on non-rigid materials such as wood or plastic. Guangdong Yueluo Hardware Industry Co., Ltd. has a threaded part with a taper angle and a screw head. The head of the screw can be countersunk, hemispherical, or other shapes. As for the grooves for screwing, the grooves can be straight-line grooves, concave cross grooves, or grooves of other shapes.
The gasket side of the above-mentioned nut assembly is in contact with the mounting surface. When the nut is tightened, the gasket squeezes the outer cone surface to make it shrink, and the cone tip faces the same direction as the nut, thereby preventing the nut from tightening, so that the nut fixing effect is not good, and at the same time When multiple nuts need to be superimposed and fixed, two adjacent nuts cannot interact with each other, resulting in poor fixing effect.
series of nuts are known in the prior art, generally comprising an internal thread which can be threaded onto the external thread of a screw of corresponding design, or a threaded bolt. Nuts of the described type are used, for example, as nuts for fastening screw-like cable connections in conduits of sheet metal housings. Sheet metal housings of this type typically have walls so thin that they cannot be threaded, so a threaded connection of this type is required to complete the installation.
The earless retaining ring for the hole is mostly installed in the annular groove on the inner wall of the pipe fitting. The outer diameter of this kind of retaining ring is slightly larger than the diameter of the assembly round hole. When assembling, the earless retaining ring needs to be pressed into the pipe fitting. Since the inner wall of the pipe fitting is relatively smooth, the earless retaining ring is easily skewed in the pipe fitting. It needs to be adjusted several times before entering the annular groove, and the assembly efficiency is low.
In the prior art, there are two ways to feed the screws of the locking screw machine, the air blowing type and the air suction type. The air suction type is suitable for relatively small screws. If the screw size is larger than M2, smaller than M5, and the length-diameter ratio is larger than 1.4, the air-blown screw machine can be selected.
