Alloy Stainless Steel Nuts Of Size M3 - M12 Grade 4.8 Cap Type​​ Description

Alloy Stainless Steel Nuts Of Size M3 - M12 Grade 4.8 Cap Type. The use of a lock nut is one of the anti-loosening measures.

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

Here are also three types of Alloy Stainless Steel Nuts Of Size M3 - M12 Grade 4.8 Cap Type:

The first is to use two identical nuts to screw on the same bolt, and add a tightening torque between the two nuts to make the bolt connection reliable.

The second type is a special lock nut, which needs to be used with a lock washer. The special lock nut is not a hexagonal nut, but a middle round nut. There are 3, 4, 6 or 8 notches on the circumference of the nut (depending on the size of the nut and the product series of the manufacturer). Several notches are not only the focus of the tightening tool, but also the entry point of the locking washer.

The third type is to drill through threaded holes from the outer surface of the nut to the inner thread surface (usually two, distributed at 90 on the outer surface), which are used to screw in small diameter countersunk screws for the purpose of threading Apply a centripetal force to prevent the lock nut from loosening. A lock nut with better quality on the market is inlaid with a small copper piece on the inner surface of the nut that is consistent with the thread of the lock nut to prevent the radial jack screw from directly contacting the locked thread and damaging the latter. . This kind of lock nut has gradually begun to be applied in the occasion of the shaft end locking of rotating parts, such as the anti-loosening of the bearing at the mounting end of the ball screw.

Hexagon nuts (GB6170/DIN934), thin nuts (GB6172/DIN439), heavy nuts (metric, American), nylon lock nuts (DIN985-DIN982 thick type), all metal lock nuts (DIN980M), cap nuts (DIN1587) ), flange nut (GB6177/DIN6923), flange nut nylon lock nut (DIN6926), four-corner weld nut (DIN928), hexagon weld nut (DIN929), butterfly cap (GB62, DIN315, American), K cap Wait. Specification: M1.6-M64
