What is the difference between standard hex nuts and heavy hex nuts?

‌The main differences between standard Hex nuts and heavy Hex nuts are appearance, function and usage scenarios. ‌

Appearance differences

There are obvious differences in appearance between standard Hex nuts and heavy Hex nuts. Heavy Hex nuts are taller and wider than standard Hex nuts, and their diameter is larger than that of standard Hex nuts.

Functional differences

‌Standard Hex nuts‌: Suitable for fastening devices in general situations, with medium bearing capacity and fatigue resistance. If the fastening part needs to be disassembled frequently or is subjected to huge tension and torque, it is recommended to use heavy Hex nuts‌.

‌Heavy Hex nuts‌: With higher bearing capacity, they are suitable for fastening devices that require a higher safety level, such as high-speed trains, equipment in hazardous locations, etc. In these applications, the use of heavy Hex nuts can ensure the tightness of the device‌.

Specific application scenarios

‌Standard Hex nuts‌: Suitable for general fastening devices, suitable for machines, equipment or structures with rough surfaces and low precision requirements‌.
