Fasteners are the easiest way to join any two or more objects. It is possible to remove them without causing any defects in the object, making it the preferable choice over adhesives and welding.

It is easy to tighten and loosen the threaded fasteners on any surface. The threaded fasteners include- screws, nuts, and bolts.

There are two ways to create a threaded fastener- rolled threads and cut threads.

What are Rolled Threads?

In rolled threading, the rod goes through a tightly pressed steel die. Unlike the cut threads, no fastener material is removed from the steel rod.

The steel dies are either flat or round. The dies have a similar thread pitch matching to the one to be formed on the fastener.

The cold forging method is the popular choice to create rolled threaded fasteners. The pressure from the steel dies protrudes in the blank space of the fastener. This method does not disrupt the structural integrity of the threaded fastener and enhances its strength.

Since no material is cut, it brings a smoothness to the rolled threaded fasteners and is more resistant to adverse climate conditions.

What are Cut Threads?

The cut thread fastener manufacturing process involves cutting the metal from the blank space using a machine. The machine rotates around the fastener and forms the threads.

It is possible to fabricate cut threads of any specifications, and it is the predominant advantage over rolled thread fasteners.

Advantages of Rolled Thread over Cut Thread

The top fastener industries India prefer rolled thread fasteners for production machinery rather than cut thread fasteners for the following reasons.

Higher Strength and Resistance

The rolled thread fasteners are produced using the cold die method. The grains on the metal piece flow in different directions because of the high pressure from the steel dies, thus enhancing the strength of the fastener.

Further, the fabrication of rolled thread fasteners offers a rounded root radius, which provides a smooth installation process and better fatigue resistance.

Whereas the cutting process of cut thread fasteners causes tiny marks perpendicular to the direction of the threads, and this disrupts the fastener’s stability over time. Moreover, the cutting process leaves sharp edges, which makes it more prone to withering and weakening strength.

Reduced Manufacturing Cost

The cutting process takes a longer time to form the threads and thus longer labour hours. It increases the overall manufacturing cost of cut thread fasteners.

Whilst the rolled threads have shorter bodies and less weight. Also, they have a quicker manufacturing process. Hence, less cost-effective fasteners.
