What do you know about DIN982 prevailing Torque Type Hexagon Thick Nuts with Non-Metallic inserts in industrial machinery structure connection?

DIN982 prevailing Torque Type Hexagon Thick Nuts with Non-Metallic inserts, also often called nylon locknuts, are an effective torque type locknut. The nylon lock nut is embedded in the top of the nut, with an inner diameter approximately equal to the small diameter of the thread nylon ring, through riveting pressure fastening to fix it.

DIN982 prevailing Torque Type Hexagon Thick Nuts with Non-Metallic Insert Locking Principle

DIN982 prevailing Torque Type Hexagon Thick Nuts with Non-Metallic Insert mainly rely on the interference fit between the nylon locking ring and the bolt threads to increase the friction between the threads to realize the locking function. The locking performance of Thick Nuts with Non-Metallic Insert can be illustrated from the following three aspects. Please get in touch with our team if you need high-quality DIN982 prevailing Torque Type Hexagon Thick Nuts with more detailed specifications and related information. Email:adelajonly@gmail.com,www.juxinfasteners.com.

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 bolt threads squeeze the nylon ring. The nylon ring fills the gap on the side of the threads (similar to the tapping process of the self-tapping nail), and the friction resistance on the side of the threads increases.

2) After the bolt is screwed into the nylon ring, the threads are formed on the nylon ring and closely matched with 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 lateral 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 stop the relative movement. Hence, the nylon lock nut vibration anti-loosening life is very high.

DIN982 prevailing Torque Type Hexagon Thick Nuts with Non-Metallic Inserts are a commonly used fastening element. They have good anti-loosening and anti-vibration properties and can be applied to many fields, such as machinery, automotive, electronics, aviation, etc. However, the sizes of prevailing Torque Type Hexagon Thick Nuts with Non-Metallic inserts are different, and for various applications, we need to choose various sizes. Below, we will introduce the knowledge about prevailing Torque Type Hexagon Thick Nuts with Non-Metallic Insert size.

Information about DIN982 prevailing Torque Type Hexagon Thick Nuts with Non-Metallic Inserts

Before choosing DIN982 Prevailing Torque Type Hexagon Thick Nuts with Non-Metallic Insert, we need to know the relevant information about the product, including thread specification, material, surface treatment, and locking performance. Usually, Prevailing Torque Type Hexagon Thick Nuts with Non-Metallic Inserts are made of plastic, nylon, fiberglass, etc.; their thread sizes are usually M2-M20, etc. In addition, we need to choose the appropriate surface treatment according to the actual needs, such as zinc plating, chrome plating, zinc-nickel, nickel, anodizing etc., nickel, anodized, etc.

DIN982 Prevailing Torque Type Hexagon Thick Nuts with Non-Metallic Insert Measuring Thread Diameter and Pitch

Thread diameter and pitch are critical parameters in sizing Prevailing Torque Type Hexagon Thick Nuts with Non-Metallic Insert. Thread diameter is the outer diameter of the inner diameter of the nut, usually measured by caliper, with 0.1mm as the minimum scale. The pitch is the distance between two adjacent threaded arcs, traditionally measured with a caliper or caliper, with a minimum scale of 0.05mm.

DIN982 Mil. Spec. Nylon-Insert Locknuts Size Selection According to Thread Specification

According to the known thread specifications and the measured thread diameter and pitch, we can select the appropriate size of non-metallic insert hexagonal locknuts. For thread sizes M2-M20, there is a standardized table of corresponding sizes for our reference. Usually, the table lists different thread specifications and corresponding dimensions, including inner diameter, outer diameter, thickness, etc. We can choose the corresponding dimensions according to our needs.

These locknuts are manufactured and tested to strict U.S. military standards for material and construction. The nylon insert grips the screw to prevent loosening from moderate vibration without damaging threads. However, the insert may become brittle if exposed to high temperatures. These locknuts are reusable a handful of times, but the holding power decreases with each use.

Rated Grade 2, Class 6, or lower, these locknuts are about half as strong as medium-strength nuts. Use them with screws that have a similar strength rating to avoid stripping threads during installation.

Cadmium Yellow-Chromate-Plated Steel—These locknuts have good lubricity and thread on smoothly and efficiently. The plating also creates a barrier against rust comparable to zinc yellow-chromate plating.

 Note the importance of size selection！

It should be remembered that the choice of size is critical. If the size is too large, the tightness of the product will be affected; if the size is too small, the Prevailing torque-type hexagon nuts with non-metallic inserts will be easily damaged.

If the size is too large, it will affect the tightness of the product. Therefore, when choosing, you need to carefully calculate and refer to the actual application to select the most suitable size to ensure the regular operation of the product.

The different sizes of DIN982 Prevailing torque-type hexagon nuts with non-metallic inserts are significant for various applications. We should understand the relevant information and choose the right size according to the thread diameter and pitch; do not choose wrongly. We can ensure the product can be used efficiently and safely by selecting the correct size.

These locknuts are manufactured and tested to strict U.S. military standards for material and construction. They are about half the height of standard-profile locknuts to fit in spaces with low clearance. You can also use them as jam nuts by threading them against a hex nut to hold them in place. The nylon insert grips the screw to prevent loosening from moderate vibration without damaging threads. However, the insert may become brittle if exposed to high temperatures. These locknuts are reusable a handful of times, but the holding power decreases with each use.
