NHY
Our custom CNC machined knurled metal pin is a high-performance positioning and connection component engineered for industrial mechanical assemblies, automation equipment, and mold systems. Featuring a knurled shaft for anti-slip performance and a unique dual-end design (tooth-shaped head and inner-hole tail), it is produced via advanced CNC turning, knurling, and precision grinding processes to achieve tight dimensional tolerances. Crafted from wear-resistant stainless steel or alloy steel, this metal pin delivers reliable friction fixation and precise docking performance, resisting abrasion and deformation under long-term industrial operation. Fully customizable in shaft diameters, lengths, and end structures, it caters to diverse connection and positioning needs across automation, mold, automotive, and electronic industries, ensuring stable assembly and efficient power transmission.

3.Application Case
A mold manufacturer utilized our alloy steel metal pins in plastic injection molds, securing movable mold cores with the knurled anti-slip shaft. The wear-resistant material withstood 100,000+ mold opening/closing cycles, maintaining positioning accuracy within 0.003mm and reducing mold maintenance downtime by 28%.
An automotive OEM deployed our stainless steel knurled metal pins in dashboard component assembly, fixing delicate trim parts under vehicle vibration. The corrosion-resistant finish and anti-slip design eliminated part loosening issues, meeting automotive quality standards and reducing after-sales complaints by 32%.
