Trusted by leading manufacturers.
Components used in safety-critical and performance-critical systems where quality cannot fail.
From the F-35 to your refrigerator.
For more than 60 years, Small Parts has manufactured the components that move, power, connect, and protect critical systems. Six markets. One quality standard. Every part qualified to the requirements of the application.
Aerospace
Precision components meeting AS9100:D and NADCAP standards for defense and commercial aerospace applications. Where failure is not an option.
“SPI manufactures parts for military gun scopes, Patriot missiles, and the F-35 fighter jet. Our aerospace quality systems ensure every component meets the most rigorous standards in the industry.”
Automotive
Powertrain, EV, safety, and chassis stampings produced at IATF 16949 quality levels. Components engineered for the road, the lifecycle, and the warranty claim that never comes.
“These may look like small parts, but there is a lot riding on them. While just a handful out of thousands of components in an automatic transmission, the cost to replace a bad one is just as expensive. We manage the entire process beyond stamping — from material selection to heat treating and finishing.”
Electrical & Power
Connectors, terminals, bus bars, and power distribution components for residential, commercial, and industrial systems.
“We specialize in high-quality stamping solutions for the power and signal industries. Our precision-engineered components ensure reliable performance — from electrical power systems to communication networks. Lighter weight, lower power loss, longer life, and lower cost.”
Industrial Equipment
Durable stamped components for heavy-duty machinery and industrial applications, with the cross-border footprint to support flexible supply.
“From brackets to complex assemblies, we produce components that meet the demanding requirements of industrial equipment manufacturers. Our cross-border manufacturing provides flexibility and cost advantages — same quality and service whether you need product from the U.S. or Mexico.”
Consumer & Appliance
High-volume precision parts for appliance manufacturers and consumer product assemblies — where cost-per-part and consistency at scale both matter.
“High-volume production with consistent quality. Our multi-slide and four-slide capabilities are ideal for the complex geometries required in consumer and appliance applications — clips, springs, brackets, and small assemblies that ship by the millions.”
Transportation
Critical components for rail and commercial vehicle systems requiring exceptional durability and traceability.
“Safety-critical components produced with automotive-grade quality systems and delivered through our North American manufacturing footprint for reduced logistics complexity, faster timing, and tighter change management.”
Working alongside the best.
From Tier 1 automotive suppliers to defense primes to global power and signal leaders, our customers trust us with the parts they cannot afford to fail.
From the lab to the launchpad.
A handful of the applications powered by our components — across mission-critical, performance-critical, and high-volume programs.
Precision stamped components qualified to AS9100:D for the world’s most advanced multi-role fighter platform.
Mission-critical components built to defense specifications, with full traceability from coil to crate.
Medical-grade cleaned components for life-changing devices where precision and cleanliness specifications are non-negotiable.
Bus bars and terminals for electrified powertrains, produced at IATF 16949 quality levels with non-ferrous materials expertise.
Copper-based components for residential, commercial, and grid-scale electrical systems — lighter, lower-loss, longer-life.
Tight-tolerance precision components for defense optics — qualified to ITAR-controlled programs and tested to mil-spec environments.
If it needs to be precise, we can make it.
Whether you’re qualifying a new program or transferring an existing one, our engineers will help you find the right path through manufacturing.
