Service HotlineThe nuts in the prior art are easy to fall off during work, especially in harsh environments or environments with large vibrations. Sometimes it is necessary to add parts such as gaskets to prevent them from falling off, but they are still easy to fall off and cause harm.
Slotted round nut, side hole round nut, end face hole round nut, small round nut round nut, ring nut, wing nut copper nut, inlaid copper nut, knurled copper nut, embedded copper nut, injection copper Nuts and other alloys zinc-copper alloy nuts and other anti-loosening principles Edit the locking nut The locking nut DIC-LOCK locking nut is composed of two parts, each part has a staggered cam, due to the internal wedge design, the slope angle is greater than the bolt's The angle of the nut, the combination is tightly integrated into a whole. When vibration occurs, the raised parts of the DIC-LOCK locknut stagger with each other to generate lifting tension, thereby achieving the anti-loosening effect.
Convex washers are mainly punched out of iron plates. The shape is generally a flat washer with a hole in the middle. Flat washers are usually thin pieces of various shapes to reduce friction, prevent leakage, isolate, prevent loosening or Dispersing pressure, the rationality of its design structure and the safety during use are very important.
Screw (pinyin: luógǎn, English: screw): a cylinder with a spiral groove cut on the outer surface or a cone cut with a tapered spiral groove. The screw has a different head, the head is called an external hexagon screw. There are others, such as large flat screws, socket head screws and so on.
The bolt performance grade label consists of two parts of numbers, which represent the nominal tensile strength value and yield ratio of the bolt material respectively. For example: a bolt with a performance level of 4.6, its meaning is: 1. The nominal tensile strength of the bolt material is 400MPa; 2. The yield ratio of the bolt material is 0.6; 3. The nominal yield strength of the bolt material is 400×0.6=240MPa Grade 10.9 high-strength bolts, after heat treatment, can reach: 1. The nominal tensile strength of the bolt material reaches 1000MPa; 2. The yield ratio of the bolt material is 0.9; 3. The nominal yield strength of the bolt material reaches 1000×0.9=900MPa class
