Heavy Hex Flat Nut

Heavy hex flat nut is applied in machinery, construction or any industry that requires strong and low-profile fasteners. Unlike ordinary hexagonal nuts, they are thicker and can adhere flat to surfaces, making them highly suitable for confined spaces.

Product details and parameters

Even heavy hex flat nut will wear out. Check the nut for cracks, rust or rounded edges. Any damage means it needs to be replaced with a new one. If the nut can rotate freely on a clean bolt, it indicates that the thread has worn out. High temperatures and stress will reduce the strength of the nut over time. Do not mix nuts of different grades: If an A-grade nut is placed on an 8-grade bolt, the consequences will be unimaginable.

Heavy hex flat nuts play a significant role in situations where large-sized nuts cannot be installed. For example, conveyor belts, car frames or industrial equipment with limited space. Their flat surfaces reduce protrusions, thereby lowering the risk of catching or getting damaged. They are also very common in piping systems. No one wants nuts to protrude and jam debris. Professional tip: Use the heavy hex flat nut in combination with the flat washer to evenly distribute the load. If your job requires nuts that are both strong and compact, then this type of nut is perfect for you.

Installation Process

When installing the heavy hex flat nut, use a torque wrench to tighten it until it meets the specifications. Excessive tightening can cause thread wear, while insufficient tightening can lead to thread loosening. The surface of the nuts is flat, which means they will be flush. Therefore, please check if they are aligned. If the surface is not smooth, please add a gasket to prevent scratches. In addition, do not reuse the old nuts at the key joints. Replace them with new ones to avoid damage.
