Our factory offers the M10 Hot Dipping Solar Panel Retaining Steel Vandal Proof Shear Nut, providing a reliable solution for preventing loosening. This particular nut design alters the thread angle, creating a 60-degree normal force in contrast to the typical 30-degree angle found in regular threads. This change significantly increases the friction force against loosening, surpassing the clamping pressure.
By modifying the thread angle, this nut design ensures that the force distribution is even across the entire contact helix, preventing concentrated loads on specific thread surfaces. This prevents the deformation of the top teeth of the male thread when engaging with the female thread, extending the lifespan of the coupling pair.
This innovative deformation mechanism allows for repeated removal and reattachment, ranging from 5 to 50 times, while still maintaining its anti-loosening functionality. Its exceptional resistance to vibrations, lightweight nature, and ease of disassembly have established it as a highly dependable anti-loosening product in various applications.

In scenarios where nuts might loosen due to movement or vibration, a range of locking mechanisms is employed: lock washers, jam nuts, specialized adhesives like Loctite, safety pins (split pins), lockwire used with castellated nuts, nylon inserts (such as Nyloc nuts), or threads with a slightly oval shape.
The hexagonal shape is the most common for nuts, mirroring the reasons behind bolt heads sharing the same form. Its six sides offer versatility for tool access, especially in confined spaces. However, shapes with more sides don't provide sufficient grip, while those with fewer sides take longer to rotate fully. Specific shapes like wingnuts aid in finger adjustments, and captive nuts (like cage nuts) cater to inaccessible areas.
Nuts vary widely, spanning from everyday household hardware to specialized designs for industrial and technical requirements. Fasteners in automotive, engineering, and industrial settings typically demand precise torque application using a torque wrench. Nuts are graded according to strength ratings aligned with their corresponding bolts. For instance, an ISO property class 10 nut is designed to withstand the proof strength load of an ISO property class 10.9 bolt without stripping. Similarly, an SAE class 5 nut matches the proof load of an SAE class 5 bolt, maintaining compatibility across the system.
