DATIAN（DT）Fastener is a leading manufacturing-based hex nut company and hex nuts manufacturer in China. We, a high-quality nuts and bolts factory, have in house heat treatment machine used to change the hardness and mechanical properties of hexagonal bolt nuts in order to serve various markets. Hexagon nuts are most common parts meant to mate hex bolts, threaded bars, stud bolts and etc. Bear in mind, Hex is short for hexagon, which means the bulk hex nuts all have six sides.

What Is A Hex Nut Used For

Hexagon nuts such as heavy hex nuts provided by heavy hex nut manufacturers are used in conjunction with bolts and studs to connect and fasten parts. Nuts are a must-have for all production machinery. It is a fastener with internal threads and used in conjunction with bolts, studs, etc., and uses the frictional force of threads to transmit power. There are many kinds of hexagon nuts, we commonly have hexagon nuts such as national standard, British standard, American standard, Japanese standard and so on.

What Is The Difference Between A Hex Nut And A Jam Nut

Visually, both hex nuts and jam nuts have 6 faces. But there is usually one more nylon ring on the top of the jam nut than the hex nut. This makes them have different performances in the anti-loosening function.

Simply put, the jam nut has an anti-loosening effect and does not require other accessories, while the general hexagonal nut needs to be equipped with other accessories to achieve the anti-loosening effect, such as the use of washers.

Jam nuts have better vibration resistance than hex nuts such as GB6170. When the thread is tightened, the crest thread of the bolt tightly enters the 30° wedge-shaped slope of the jam nut and is clamped, and the normal force exerted on the wedge-shaped slope forms an included angle of 60° with the axis of the bolt. Instead of an included angle of 30°, the normal force generated when the anti-loosening nut is tightened is much larger than that of standard nuts, and it has great anti-loosening and anti-vibration capabilities.

How to choose bewteen finished hex nuts and heavy hex nuts

The first step in choosing any nut is to ensure the accuracy of the nut's go-stop gauge. Datian Fasteners can assure all customers that the accuracy of the go-stop gauge of our nuts can reach more than 95%. If some customers have higher requirements, such as "one-time rolling", our pass-stop gauge accuracy can reach more than 99%.

The hardness and proof load strength of finished standard nuts are worse than heavy hexagonal nuts, so in the selection of practical application scenarios, heavy hexagonal nuts are more suitable than finished hexagonal nuts in bridge construction, ship construction, railway construction, wind power generation and oil pipeline construction. application.
