Low-volume production places higher demands on consistency and delivery efficiency. Backed by high-precision equipment and a stable production system, KT maintains reliable output even in small batches—ensuring each part meets consistent dimensional accuracy and quality standards. By minimizing batch variation and uncertainty, we help reduce trial risks and keep projects moving forward efficiently.
When handling high-mix, low-volume demands, KT remains responsive while maintaining delivery pace, without compromising quality or lead time.
Detailed Description
This precision threaded locating pin is a general-purpose guiding and connecting part for mold fixtures, automation equipment and precision transmission mechanisms. Integrally CNC turned from stainless steel bar, with precision ground smooth cylindrical surface and standard precision external threads at both ends, featuring high concentricity. The smooth shaft section enables precise sliding guidance and positioning limit, while the threads at both ends can cooperate with nuts for axial locking fixation, height adjustment and component connection. It is corrosion-resistant, rust-proof, high-rigidity and wear-resistant, with excellent batch consistency and thread interchangeability.
