Heavy Hex Structural Nut

Heavy hex structural nut is used in heavy industries such as Bridges, towers or industrial frames. These nuts adopt thicker and wider shapes and can withstand extreme loads and vibrations. You just need to tighten the nuts correctly. These nuts require uniform pressure to be safely locked.

Product details and parameters

The heavy hex structural nut requires appropriate washers. The outer diameter of the washer should match the width of the opposite side of the nut. Please use the torque value specified in the project file. Is lubrication needed? Carry out only under the specified circumstances; Some coatings can act as lubricants. If the nut is reused (not recommended in critical applications), please check whether the thread is deformed.

To select the appropriate heavy hex structural nut, it is necessary to understand the bolt size first. These nuts follow strict size rules. For example, a bolt with a diameter of 1 inch is paired with a flat nut with a diameter of approximately 1.5 inches. Pitch is also important: Use coarse threads for general purposes, and use fine threads if vibration is a concern. We have stock sizes ranging from ½ inches to 4 inches in diameter. Professional tip: Be sure to order nuts and bolts from the same batch to avoid fit issues. Although mixing and matching can save money, the cost of rework is very high.

Heavy Hex vs Standard Nuts

Why spend more money on heavy hex structural nut? Ordinary nuts are not suitable for structural engineering. Heavy hex structural nut has a larger load-bearing surface, thereby reducing the risk of material embedding under load. It is also thicker. If you measure the height, you will find that they are thicker than ordinary nuts. This volume means better thread meshing and shear resistance.
