Principle of Stainless Steel Nuts: The working principle of a nut relies on the friction generated between the nut and a stainless steel bolt to achieve self-locking. However, under dynamic loads, the reliability of this self-locking mechanism diminishes. In critical applications, specific anti-loosening measures are therefore implemented to ensure the reliability of the nut's locking action. The use of stainless steel locking nuts constitutes one such anti-loosening measure.
A specialized stainless steel nut-distinct from the standard stainless steel hexagon nut-is a type of round nut featuring six notches cut into its circumference. These six notches serve a dual purpose: they act as the engagement points for the tightening tool and as the insertion points for the tabs of an anti-loosening washer. This second method of anti-loosening is considered more reliable than the first, though its structural design is relatively more complex. What is the difference between a "locking nut" and a "self-locking nut"? The primary function of a self-locking nut is to prevent loosening and resist vibration; they are typically employed in specialized applications. The terms "locking nut" and "self-locking nut" essentially refer to the same concept: any nut equipped with a self-locking capability is classified as a locking nut. Specific standards regarding the required tightening torque and removal torque exist for these components; for reference, one may consult a mechanical design handbook or relevant national standards for nuts.
