Buy Pin & Socket Contacts in Bulk | Manufacturer

A socket contact is the female half of an electrical connector pair — a hollow receptacle designed to receive and retain a pin contact. Socket contacts are found in PCB connectors, automotive harnesses, medical devices, and industrial equipment. They provide secure electrical continuity by gripping the mating pin through spring tension or retention features.

Electropin manufactures pins from lead-free brass, stainless steel, and other metals depending on application requirements. All material options are lead-free, eliminating REACH and RoHS compliance concerns without requiring leaded brass as many machined-pin suppliers do.

Electropin offers four retention feature types: Star, Tabs/Spline, Inscribed Square, and Flat. The Star feature can expand diameter up to 50% greater than the wire raw material, providing strong anti-rotation and pull-out resistance for press-fit, PCB through-hole, and post-insertion into plastic applications.

Electropin pins support press-fit into metal, through-hole PCB mounting, post-insertion into molded plastic parts, and high-speed automation applications. Each mounting method is accommodated through specific retention feature geometries produced during the cold-forming process, ensuring secure mechanical and electrical performance.

When raw materials are available, Electropin can begin manufacturing and deliver your first batch in as little as two weeks. Subsequent batches are delivered on a customer-specified timeline, and production volume can be scaled dramatically when demand increases — up to five pins per second.

Yes. All Electropin pins are manufactured using lead-free materials, which fully eliminates REACH and RoHS compliance concerns. Unlike machined pin manufacturers that rely on leaded brass, Electropin's cold-forming process works with lead-free brass and stainless steel, making compliance straightforward for medical, automotive, and electronics customers.
