NUT

Nut is a part that is screwed together with bolts or screws for tightening. It is a component that all manufacturing machinery must use. According to different materials, it is divided into carbon steel, stainless steel, non-ferrous metals (such as copper), etc. type.

Nuts are parts that tightly connect mechanical equipment. Through the inner threads, nuts and bolts of the same specifications can be connected together. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts (in the nut , M4 means the inner diameter of the nut is about 4mm, and 0.7 means the distance between the two thread teeth is 0.7mm); the same goes for American-made products, for example, a 1/4-20 nut can only be matched with a 1/4-20 screw ( The inner diameter of a 1/4 finger nut is approximately 0.25 inches, and there are 20 teeth in each inch of a 20 finger nut).

Nuts are divided into the following categories according to different materials:

Stainless steel

1. Self-locking nuts, lock nuts, locking nuts, four-claw nuts, screw-in nut safety nuts, thin rod screw connecting nuts, self-locking hexagonal cap nuts, nuts for special anchor screws, hexagonal crown thin nuts, Eye nut.

2. Fine thread full metal hexagon flange face lock nut, full metal hexagon flange face lock nut, fine thread non-metallic insert hexagon flange face lock nut, fine thread hexagon flange face nut

3. Welded square nuts, welded hexagonal nuts, fastening nuts, embedded round nuts

4. Slotted round nuts, round nuts with holes on the side, round nuts with holes on the end, small round nuts

5. Round nuts, ring nuts, wing nuts

Copper

Copper nuts, inlaid copper nuts, knurled copper nuts, embedded copper nuts, injection molded copper nuts, etc.

Alloy

Zinc copper alloy nuts, etc.

Anti-loosening principle

The DISC-LOCK lock nut is composed of two parts, each part has a staggered cam. Since the internal wedge design has a slope angle greater than the nut angle of the bolt, this combination is tightly meshed into a whole. When vibration occurs When the DISC-LOCK anti-loosening nut is moved, the convex parts of the lock nut move against each other to generate lifting tension, thereby achieving a perfect anti-loosening effect.
