Custom Contact Pins in Bulk | Manufacturers & Suppliers

Electropin manufactures custom contact pins in lead-free brass, stainless steel, and other metals. All standard options are lead-free, eliminating REACH and RoHS compliance concerns that are common with leaded brass used in traditional machined pins. Material selection depends on your electrical, mechanical, and regulatory requirements.

Electropin offers four retention feature types: Star, Tabs (Spline), Inscribed Square, and Flat. The star feature can expand pin diameter up to 50% greater than the wire raw material diameter, providing strong press-fit or post-insertion retention for metal and molded plastic assemblies.

Custom contact pins from Electropin support three primary mounting methods: press-fit into metal, through-hole PCB mounting, and post-insertion into molded plastic parts. Certain pin types, such as grooved and hinge pins, also support high-speed automation assembly where pins slide down tracks without requiring orientation.

When raw materials are available, Electropin can begin manufacturing and deliver your first batch of cold-formed pins in as little as two weeks. Subsequent production batches are delivered on a customer-specified timeline, and production volumes can be scaled up significantly when your needs change.

Yes. Because Electropin manufactures with lead-free materials, all standard pins eliminate the REACH and RoHS compliance concerns associated with conventional leaded brass machined parts. No special documentation or material substitution is required — compliance is built into the manufacturing process by default.

Electropin's custom contact pins serve automotive connectors, farm equipment electrical connections, computer and electronics connectors, medical device connectors, and circuit board assemblies. Their cold-formed pins are engineered for demanding environments where dimensional consistency and high retention strength are critical to product reliability.
