Precision Connector Pins
Manufactured by Swiss Screw Machining
Custom machined connector pins for demanding electrical, electronic, medical, and industrial applications — produced with tight tolerances, excellent surface finish, and reliable high-volume consistency.
Why Swiss Screw Machining Is Ideal for Connector Pins
Connector pins are often small, slender, and tolerance-sensitive, making them an excellent fit for Swiss screw machining. The Swiss process provides enhanced stability during machining, especially valuable for long, thin, or miniature components.
Swiss machining is widely used for miniature and precision cylindrical parts because it supports intricate features, tight tolerances, and repeatable output at production scale.
High Precision
Maintain tight dimensional control on critical diameters, shoulders, and mating features.
Miniature Part Capability
Ideal for small connector pins and micro-scale turned components.
Excellent Repeatability
Stable process control for medium- to high-volume production runs.
Superior Surface Finish
Support smooth insertion, reliable contact performance, and downstream plating quality.
