You will find the most direct, yet detailed answers to basic questions, you often ask about stainless steel hex lock nuts.

Without further ado, here we go:

1. What Is A Lock Nut?

The lock nut is a kind of nut widely used in machinery and other industries. The working principle of the nut is self-locking by the friction between the nut and the bolt. However, the reliability of this self-locking under dynamic load will be reduced. On some important occasions, it will need to take some anti-loosening measures to ensure the reliability of the nut locking. The lock nut is one of the anti-loosening measures.

The lock nut material includes carbon steel, stainless steel, copper, alloy, etc. And the lock nut is used to lock the close pipe nipples or other pipe fittings.

The anti-loosening effect of the lock nut mainly depends on the interaction force between the nut and the bolt engaging thread. There are many ways to improve the interaction force between meshing threads, such as structural improvement of nut threads and surface treatment of threads, etc.

Lock Nut Types

• The first type 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 together 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.
• The fourth type of lock nut is composed of two parts, each part has a staggered cam. Because the internal wedge design slope angle is greater than the bolt nut angle, this combination is tightly bitten into a whole, when vibration occurs At this time, the raised parts of the locknut are staggered to each other to generate lifting tension, so as to achieve a perfect anti-loosening effect.
• The fifth type is structural anti-loosening. Through the design improvement of the thread structure, it does not rely on other external factors to obtain its own locking function. Therefore, its applicability is wider than the above-mentioned methods, and the requirements for the environment are also relatively low.

2. What Is A Stainless Steel Hex Lock Nut?

The stainless steel hex lock nut, hexagonal in shape and internal thread, is cast from 304/316 stainless steel, which belongs to a kind of stainless steel threaded pipe fittings.

Stainless Steel Hex Lock Nut Advantages

Stainless steel lock nuts have excellent corrosion resistance and are used in food, chemical, petroleum, and other highly corrosive environments. And the use of stainless steel hex lock nuts lengthens the life of equipment, reduces maintenance and repairs, and can prevent injury or death from product damage. 

• Simple & effective all-steel construction.
• Requires no special tools for installation.
• Reusable and infinitely adjustable over and over for repeated maintenance.
• Do not damage or deform the bolt thread.
• Proven for decades in the most demanding applications.
• Holds in any position on the bolt.
