Thread Rollers

Thread rolling of bolts increases the tensile strength of the material, making it suitable for anchor bolts, studs and cylinder assemblies. Fixed length or rod production comes standard on all models of thread roller purchased through African Machine Supplies. 

There are many competing manufacturing methods to create screws and bolts, and thread rolling is one of the leading ones at it produces a structurally sound high performing bolts at a high rate. 

How does it work?

Thread rolling is one of the most efficient ways of creating bolts, both in speed and material requirements.  The method behind rolling a thread is that a blank bolt is passed through a set of turning dies. These dies roll the blank bolt between them and from the thread into it. 

Only ductile materials are able to be rolled, and the threads are cold formed. However, this increases the thread’s yield strength, surface finish, hardness, and wear resistance. This allows thread rolling to be a viable manufacturing method for pipe thread, scaffold thread, threaded bars and anchor bolts. 

What you can expect from us 

At African Machine Supplies, our thread rollers will be able to shape and form a variety of bolts out of most ductile materials. Thread rolling is an extremely profitable business, and we have the right tools for the job. 

1. Durability
   Thread rollers are a constant operation machine. As such they need to be able to handle extended periods of being in and working. With that in mind, the thread rollers at African Machine Supplies are built to be tough and will last a number of years. 
2. High Production Capacity
   With and average production time of one bolt per second, thread rolling is a very highly efficient method of creating bolts. Ideal for large production runs, thread rolls can form thousands of bolts per day, meaning that they are very profitable pieces of machinery
3. High Tensile Strength
   The cold forming production of thread rollers ensures that the bolts produced are of a very high quality. The tolerances are extremely tight due to the pressure forming method, and the work hardening of the material creates a very hard material with a very high tensile strength
