Roll vs. Cut Thread – A Full Breakdown

Most threaded fasteners can have their thread either cut or rolled. Each method has their own advantages as well as disadvantages, along with a combination of differences and misconception. 

The following information is designed to clear the air around the two methods of producing threaded fasteners ends.

WHAT IS CUT THREAD?

Cut thread is when the round rod has a section removed from it completely from a swift cut.

WHAT ARE THE ADVANTAGES OF USING CUT THREAD?

Cut threads allow users to have few limited restrictions when it comes to diameter and thread length.

WHAT ARE THE DISADVANTAGES OF USING CUT THREAD?

Due to the amount of time and labor it requires to produce cut thread fasteners compared to roll thread fasteners, the cut thread fasteners typically are more expensive. If price does not determine your purchasing decisions, then cut thread has no noticeable disadvantage.

WHAT IS ROLL THREAD?

Roll thread is where steel is extruded to form a threaded portion of the fastener instead. The process utilizes hardened steel rolls and creates external threads that are the reverse of the working surface of the fastener.

WHAT ARE THE ADVANTAGES OF ROLL THREAD?

Although thought to be of lesser strength, rolled thread is of the same strength as a cut thread fastener. The strength comes from the thread dimensions of the minor diameter, and the diameters are identical after rolling – thus no loss in strength.  

Roll thread takes significantly less time and labor to produce, thus it is the cheaper option while still not compromising strength. The cold working of metal during the rolling process also improves the physical characteristics of the fastener – resulting in thread form properties that are greater than those of the original material.

WHAT ARE THE DISADVANTAGES OF ROLL THREAD?

Roll thread does produce a reduced body diameter.
