Thread Rolling

We have made further investment in our machining capacity with the addition of several Thread Rolling machines.

The Thread Rolling process offers:

• High production rate
• No material wastage
• Uniform threads
• Improved physical characteristics
• Greater accuracy
• High level of surface finish

Tensile and Shear Strength

Thread rolling is a cold forming process and therefore increases the tensile strength.

When compared to screw threading, a process that breaks grain flow (see fig 1 below), the advantages are immediately clear. The roll threading process manipulates the grain flow, re-forming it in continuous unbroken lines following the contours of the threads (see fig 2 below).

As a result, shear strength is vastly improved and threads resist ‘stripping’ when in situ because any failures must occur across the diameter rather than with the grain.
