HOW THREADS ARE FORMED ON M10 RODS

Industrial fastener manufacturers and mechanical engineers utilize high-speed external thread rolling machinery to cold-form uniform, heavy-duty threads onto blank metal M10 rods.

Unlike traditional thread cutting or grinding processes that remove material and sever the metal's grain structure, thread rolling is a chipless cold-forming technique. The machine passes a smooth, precisely sized cylinder blank between hardened steel rolling dies under immense hydraulic pressure. As the dies compress and rotate the metal rod, they plastically displace the material, forcing it to flow into the die's thread profile. This strategic displacement work-hardens the surface, burnishes the flanks, and preserves a continuous, uninterrupted grain flow along the thread profile, resulting in an M10 rod with superior tensile strength, excellent fatigue resistance, and absolute dimensional precision.
