Rolled Threads Vs. Cut Threads

When it comes to choosing an industrial fastener, you want to ensure that the threads on the fastener are constructed in a way that will meet your application needs. Fastener threads are usually created by one of two processes: rolling or cutting.

Understanding the differences between the two and identifying the benefits each process offers will help you better select your industrial fasteners in the future.

Rolled Threads

Specialized dies are used in the creation of rolled thread fasteners. The fastener material passes through these dies at high pressures. This process results in the creation of perfectly formed threads that have solid thread roots.

Rolled thread fasteners tend to be the more affordable option because they require very little manual labor to produce.

The deforming and cold working processes that occur during the rolling process allow the base material of the bolt to become stronger. This makes rolled thread fasteners much more resilient over time.

The threads on a rolled thread fastener are very smooth, ensuring a snug fit once the fasteners are used for larger manufacturing and assembly projects.

Cut Threads

Cut threads are produced by cutting or machining into the round bar of a screw base to eliminate portions of the bar. These cutting and machining tasks allow thread roots and peaks to emerge from the bulk material of the screw base.

One of the major reasons cut thread fasteners are so popular among manufacturers is their ability to work with custom measurements. Since each cut thread fastener is created by hand, the fasteners can be made to fit any design specification required by producers and manufacturers. 

There are many factors that you must consider as you choose between rolled threads and cut threads for your fasteners.

The first consideration should always be the cost. Since rolled thread fasteners can be produced on a mass scale using automated machinery, these fasteners will be the most affordable option for large production runs. Cut thread fasteners are better suited for prototypes or small production runs because of their higher cost-per-screw.

You will also need to consider your unique design specifications. If you can't find a commercially produced fastener in the length or diameter that you desire, then cut thread fasteners offer a viable solution. The ability to customize cut thread fasteners makes these screws the perfect choice for one-off or custom projects.

The way the threads on a screw are formed can impact cost, durability, and function. Weigh your options carefully before choosing between rolled thread and cut thread fasteners.
