Female Connector Pins | Cold-Formed to Spec | Precision Manufacturer

Common types of pin connectors include solid contact pins, grooved pins, knurled pins, barbed pins, hinge pins, press-fit pins, dowel pins, PCB connector pins, die-rolled pins, and gauge stop pins. Each type is engineered for specific retention, anti-rotation, and mounting needs across industries such as automotive, medical devices, PCB assembly, and farm equipment.

Electropin manufactures female connector pins in lead-free brass and stainless steel, as well as other metals upon request. All materials are selected to ensure lead-free compliance, eliminating REACH and RoHS regulatory concerns without requiring leaded brass as traditional machined pin manufacturers often do.

Electropin achieves an industry-leading defect rate of just 1 in 600,000,000 pins. This is made possible by automatic die rolling, which involves no cutting, no heat generation, and no tool dulling — delivering consistent dimensional accuracy from the very first pin to the millionth pin in a production run.

Electropin's connector pins support press-fit into metal, through-hole PCB mounting, post-insertion into molded plastic parts, and high-speed automation applications. Multiple retention features — including star, tabs/spline, inscribed square, and flat — provide anti-rotation and high pull-out resistance tailored to each mounting method.

Yes. Because Electropin's cold-forming process works with lead-free brass and stainless steel without requiring leaded materials, all pins are manufactured to be REACH and RoHS compliant. This eliminates the compliance burden many customers face when sourcing machined pins that rely on leaded brass alloys.

Electropin can begin manufacturing and deliver a first batch of cold-formed connector pins in as little as two weeks, provided raw materials are available. After the initial run, batches are delivered on a customer-specified timeline, and production can be scaled up or down rapidly to match changing demand.

Electropin's cold-formed female connector pins are used across a wide range of industries, including automotive wiring harnesses and ECU connectors, medical device electrical assemblies, PCB and electronics manufacturing, farm equipment and agricultural machinery control systems, and general electronics applications requiring high precision and regulatory compliance.
