1 Inch Zinc-Plated Hinge Pins | Bulk Purchase

A hinge pin is measured by its outer shaft diameter, overall length, and any retention feature diameter (such as the star feature, which can expand up to 50% beyond the wire diameter). For press-fit applications, the retention zone diameter relative to the hole diameter is critical. Electropin's DFM team can help you define the correct measurements for your housing.

Electropin hinge pins are available in lead-free brass and stainless steel. Lead-free brass eliminates REACH and RoHS compliance concerns without requiring leaded alloys. Stainless steel is available for applications demanding higher corrosion resistance or mechanical strength. Custom material requests can be discussed with the engineering team during DFM consultation.

Hinge pins can be manufactured with star, tabs/spline, inscribed square, or flat retention features. The star feature provides the highest retention, expanding pin diameter by approximately 50% beyond the raw wire diameter. Each retention type offers different anti-rotation and pull-out resistance characteristics suited for plastic post-insertion or metal press-fit housings.

Electropin specializes in bulk cold-formed pin production and can scale production to your volume requirements. There is no publicly listed minimum order quantity — contact the team directly to discuss your volume needs. Production rates of up to 5 pins per second allow rapid fulfillment of large orders, with batches delivered on your specified timeline.

When raw materials are available, the first batch of cold-formed hinge pins can be delivered in as little as two weeks. Subsequent batches are scheduled on a customer-specified timeline. Electropin's scalable production also allows rapid volume increases when demand changes, without compromising delivery speed or pin quality.

Yes. All Electropin hinge pins are manufactured using lead-free brass or stainless steel, which eliminates the need for leaded alloys and fully removes REACH and RoHS compliance concerns. This makes them suitable for regulated industries including medical devices, automotive electronics, and consumer electronics where hazardous substance restrictions apply.
