The nut is a common fastener product we use, it is mainly used in conjunction with stainless steel bolts to play a relative fastening role. When using it, we must first understand its specific purpose and which fasteners can be used together to achieve the best results.
　

1. Round nut: used on shaft parts to prevent axial displacement and used with non-return washer.

2. Hexagon nuts: used in conjunction with bolts and screws.

3. Flange nut: stainless steel hexagonal flange nut has a larger ratio of support area to stress area, so it can withstand higher pre-tightening force. Therefore, it is generally used in product fields such as automobile engines and heavy machinery.

4. Slotted nut: The stainless steel slotted nut is used on the bolt with a hole at the end of the screw that is matched with it. It is inserted and locked with a cotter pin. It is mainly used for equipment with vibration load.

5. Cap nut: It has one more decorative function than ordinary nuts.

6. Wing nut: used for nuts that have low connection strength and need to be disassembled frequently, and can be turned by hand. Such as hacksaw bows, newspaper clips and other occasions.

7. Locking nut: The self-locking nut is the same as the ordinary hexagonal nut, but has the function of preventing loosening than the ordinary nut, and is generally used in the vibration connection part.
