NHY
Our custom CNC machined precision steel locating pin is a high-performance positioning component engineered for accurate alignment and fixation in industrial molds, automation fixtures, and precision mechanical assemblies. Featuring a precision-machined step structure for clear positioning stops and a smooth cylindrical surface for minimal friction, it is produced via advanced CNC turning, centerless grinding, and heat treatment processes to achieve ultra-tight dimensional tolerances. Crafted from high-strength carbon steel or stainless steel and hardened for wear resistance, this steel locating pin delivers exceptional stability and repeatability, resisting deformation and abrasion under long-term heavy loads and frequent assembly cycles. Fully customizable in diameter, length, step dimensions, and surface finish, it caters to diverse precision positioning needs across automotive, electronics, medical, and aerospace industries, ensuring consistent assembly accuracy and production efficiency.
