An Introduction to Thread Rolling Thread rolling is a cold forming or cold metal forming process that creates threads using precision thread rolling dies that are the mirror image of the thread being produced. This process is different from other processes like metal cutting, grinding, and chasing because it does not remove any metal to create the desired profile. Instead, these hardened steel thread rolls move and mold ductile metals quickly and very precisely into desired thread form. The tooth form of the thread rolls protrudes into the outside diameter of cylindrical blank workpiece to reform the surface. The workpiece typically has a blank diameter between the major and minor diameter of the thread, or close to the pitch diameter of the thread being produced. The ultimate blank diameter of the work piece will depend on material grade and ductility value. The extreme pressure from  the thread rolls  causes the blank material to move outward into the cavity between the thread rolls.

Thread bars also known as   threaded rods   or stud bolts, are versatile fasteners used in a wide range of applications across various industries. These cylindrical metal rods have threads on the entire length or on a portion of their surface, allowing them to be screwed into nuts or tapped holes. Thread bars serve several common uses: Construction and Building Industry: Thread bars  are commonly used in the construction industry for applications such as anchoring structural elements like concrete columns, beams, and walls. They provide stability and ensure the structural integrity of buildings and bridges. Civil Engineering: In civil engineering projects, thread bars are utilized for applications like soil and rock stabilization, ground anchoring, and retaining wall construction. They are essential in ensuring the stability of structures in challenging environments. Automotive and Machinery: Thread bars play a crucial role in the automotive and machinery industry, used for fastening c
