Bulk Hinge Pin Production
Order door hinge pins in high volumes directly from the manufacturer. Our automatic die rolling process produces up to five pins per second, ensuring fast fulfillment and consistent quality across every unit in your order.
Looking to buy door hinge pins in bulk direct from a manufacturer? Electropin has manufactured precision metal pins for over 80 years using proprietary automatic die rolling technology — delivering consistent, high-quality hinge pins at lower cost, faster lead times, and virtually zero defects. Whether you need standard or custom hinge pin specifications, we scale to meet your volume.
From standard bulk hinge pins to fully custom specifications, we deliver precision-formed metal pins at scale.
Order door hinge pins in high volumes directly from the manufacturer. Our automatic die rolling process produces up to five pins per second, ensuring fast fulfillment and consistent quality across every unit in your order.
Need a hinge pin with specific dimensions, diameters, or retention features? Our DFM experts collaborate with you to design a pin that meets your exact functional requirements while minimizing per-unit cost.
We manufacture hinge pins with stars, tabs, splines, inscribed squares, or flat features to provide anti-pullout and anti-rotational strength — ideal for demanding door hardware and high-cycle hinge applications.
For unique hinge pin profiles, our engineers design and build the progressive dies needed to cold-form pins to your exact specification, enabling repeatable, scrap-free production at any volume.
Our Design for Manufacturing experts review your hinge pin requirements and refine the design for optimal performance and cost efficiency — before a single pin is produced.
All our hinge pins can be produced lead-free without requiring leaded brass, eliminating REACH and RoHS compliance concerns for commercial door hardware and export applications.
Electropin's automatic die rolling technology cold-forms metal into precise hinge pin geometry — no cutting, no heat, no scrap. Based in North Carolina and serving hardware manufacturers nationwide, we deliver bulk door hinge pins with a defect rate of just 1 in 600,000,000. When your supply chain demands consistent parts from part one to part one million, no competitor can match our speed, accuracy, or cost efficiency.

Three generations of manufacturing innovation back every pin we produce — here's what sets us apart.
Our tools never dull, so every hinge pin in your bulk order meets spec — from the first unit to the millionth.
First batches can ship in as little as two weeks when raw materials are available — keeping your production line moving.
Cold-forming generates no scrap — when you pay for five pounds of material, you get five pounds of finished hinge pins.
Domestically manufactured in North Carolina, Electropin offers reliable, U.S.-based bulk supply with straightforward communication and scalable capacity.
Experienced manufacturing professionals dedicated to your pin specification needs.
Owner / Operator
Keith Brenton brings over 35 years of hands-on experience helping customers refine pin designs for optimal manufacturing outcomes. As the Owner and Operator of Electropin — legally Autoswage Products, Inc. — Keith has been the driving force behind the company's evolution since relocating operations to North Carolina and rebranding in 2019. Under his leadership, Electropin has developed and refined the automatic die rolling technologies that allow the company to produce bulk pins — including door hinge pins — faster, at lower cost, and with higher precision than any competing manufacturing method. Keith's approach is collaborative: he works directly with procurement teams, engineers, and product designers to ensure every bulk pin order meets exact dimensional and functional requirements. His deep domain knowledge spans automotive, hardware, medical, and electronics pin manufacturing.
The pin in a door hinge is called a hinge pin or pivot pin. It is the cylindrical metal rod that runs through the barrel (knuckle) of the hinge, connecting the two hinge leaves and acting as the pivot point around which the door swings. Hinge pins are typically made from steel, brass, or stainless steel.
