At Spartan Fastener, we have spent nearly 50 years perfecting the art of cold forming. By manipulating metal at room temperature rather than cutting it away, we create components that are stronger, more durable, and more cost-effective than traditional machined parts. Today, we’re highlighting three of our core service areas that help our partners across the automotive, medical, and electronics industries stay ahead of the curve.
When standard off-the-shelf parts won't suffice, our custom solutions fill the gap. We specialize in engineering fasteners tailored to unique mechanical requirements, including specialized bolts and clinch studs. The cold-forming process rearranges the grain flow of the metal, resulting in higher shear and yield strength compared to machined alternatives. Our facility is equipped to handle everything from initial prototypes to mass production runs in the millions with high efficiency. Furthermore, we are proud providers of industry-leading solutions like MAThread®, which are designed specifically to prevent cross-threading during the assembly process.
Our rivets and pins are the unsung heroes of industrial assembly, found in everything from bed frames to automotive sensors. We produce custom-engineered shoulder rivets that provide the high compressive and shear strength required for heavy-duty industrial storage racks. For clients focused on speed, our semi-tubular or hollow rivets are designed for efficient, automated assembly without the need for secondary drilling. These are available in a variety of materials, including brass, copper, and stainless steel. Additionally, our progressive forming machines produce slotted, coiled, and solid specialty pins with high repeatability and minimal scrap.
In industries like medical devices and electronics, precision is measured in microns. Spartan Fastener is a leader in the miniature fastener market, producing parts that many other manufacturers simply cannot replicate. We have the capability to produce fasteners with diameters as small as 0.019 inches while maintaining diameter tolerances as strict as ±0.001 inches. This level of precision ensures a perfect fit and function in the most delicate applications. To meet diverse technical needs, we offer these miniature solutions in lightweight aluminum, conductive copper, and high-strength stainless steel.
