NHY
Our custom CNC machined locating pin is a high-precision positioning component engineered for accurate alignment and fixation in mechanical assemblies, molds, and automated production lines. Featuring a multi-step shaft structure (including a precision locating head, smooth intermediate section, and knurled tail), it is produced via advanced CNC turning and grinding processes to achieve tight concentricity and dimensional tolerances. Crafted from wear-resistant alloy steel or stainless steel, this locating pin delivers reliable repeated positioning performance, resisting abrasion and deformation under long-term industrial use. Fully customizable in shaft diameters, lengths, and surface treatments, it caters to diverse precision positioning needs across automation, mold, automotive, and electronic industries, ensuring consistent assembly accuracy and efficient production.
