Materials: Hex nuts can be made from various materials, including steel, stainless steel, brass, and nylon. The choice of material depends on factors such as the application, environmental conditions, and desired strength.
Locking Features: Some hex nuts have locking features to prevent unintentional loosening due to vibration or other factors. Nylon-insert lock nuts, prevailing torque lock nuts, and all-metal lock nuts are examples of nuts with locking features.
Jam Nuts: Jam nuts are thinner than standard nuts and are used in conjunction with another nut to lock them together. They are often used in situations where vibration resistance is critical.
Grades and Strengths: Hex nuts are available in different grades or classes, indicating their strength and resistance to deformation. Common grades include Grade 2, Grade 5, and Grade 8 for steel nuts, with Grade 8 being the strongest.
