Non-metallic insert hexagon nylon lock nut standard introduction

What is the meaning of a non-metallic insert nylon lock nut?

A non-metallic insert lock or nylon lock nut is an effective torque-type lock. It is embedded in the top of the nut with a nylon ring whose inner diameter is similar to the small diameter of the thread and fixed by riveting.

Non-metallic insert lock nuts rely on nylon locking rings and bolt threads between the interference fit to increase the friction between the threads to achieve the locking function. Non-metallic insert lock nut locking performance can be illustrated from the following three aspects:

1. As the inner diameter of the nylon ring is smaller than the outer diameter of the bolt when the bolt is screwed into the nylon ring, the nylon ring is squeezed by the bolt threads. The nylon ring fills the gap on the side of the threads (similar to the tapping process of self-tapping nails), and the friction resistance on the side of the threads increases.

2. After the bolt is screwed into the nylon ring, it forms threads on the nylon ring and closely matches the threads on the bolt. Additional friction is generated between the bolt and the nylon ring due to the elastic pressure of the nylon. In this way, it is equal to increase the friction coefficient of the thread contact surface, thus increasing the anti-loosening performance of the nut.

3. Nylon's elasticity is good, and the mechanical properties are also relatively good; at the same time, fatigue resistance can absorb space, both in the transverse load impact, due to the bolt and the nylon ring on the extruded threads' close fit, eliminating the gap between the bolt and the nut, to control the swing of the bolt, to prevent it from moving relative to each other. Hence, the vibration of the nylon locking nut against the loosening of the life of the nut is very high.

Non-metallic inserts are inlaid with a layer of non-metallic material around the internal threads of the nut (generally made of nylon 66), which plays a locking role when it is tightened and is typically used for non-removable occasions. Locking principle: the inner thread of the nut is covered by a layer of non-metallic materials; when screwed into the outer thread, non-metallic materials are destroyed and will be threaded with the gap to fill, increasing the resistance when rotating back to play a role in locking the anti-loosening. If you need to manufacture or supply a Non-metallic insert hexagon nylon lock nut fastener, contact our customer service team at Email:adelajonly@gmail.com or www.juxinfasteners.com.

Standard specifications for hexagon nylon non-metallic insert locknuts:

Before choosing the non-metallic insert hexagon locknut, we need to know the relevant information about the product, including thread specification, material, surface treatment, and locking performance. Usually, the non-metallic insert hexagonal lock nut material has plastic, nylon, fiberglass, etc.; its thread specification is usually M2-M20. In addition, we also need to choose the corresponding surface treatment according to the actual needs, such as zinc plating, chrome plating, anodic oxidation, and so on.

Hexagonal nylon lock nut is a commonly used fastener that uses the elasticity and friction of the special material nylon to achieve tightening. Its specifications, size, and performance will be different. The following are some common standard specifications: M3,M4,M5,M6,M8,M10,M12,M14,M16,M18,M20,#6-32,#8-32,#10-32,1/4-20",5/16-18",3/8-16",1/2-13" and so on.

Hexagonal non-metallic inserts nylon lock nut precautions and selection skills:

1. Correctly select the specifications and sizes to avoid damage or jamming due to size inconsistency.

2. To ensure the locking effect, Clean the object's surface to fasten it before use.

3. When using the material in high-temperature and humid environments, consider its nature and use conditions.

4. Select the appropriate torque and loosening strength to avoid unnecessary damage caused by over-tightening or over-loosening.

Hexagonal non-metallic insert nylon lock nut FAQs:

1. Why do hexagonal nylon locknuts have a locking effect?

A: The nylon material's elasticity and friction enable it to clamp the threads tightly and prevent loosening tightly.

2. What is the applicable temperature range of hexagonal nylon locknuts?

A: Generally speaking, the applicable temperature range is between -40℃~+110℃.

3. Why does the hexagonal nylon locknut not damage the fastened object?

A: The softness and elasticity of nylon material can ease the collision strength when fastening to avoid damage.

The above are the standard specifications, characteristics, and application areas of the hexagonal nylon lock nut and the introduction of precautions and selection techniques. It is recommended that when purchasing, products that meet the specifications, dimensions, and performance requirements be chosen according to the actual needs and use of the environment.
