AMPG

At AMPG, we manufacture heavy-duty round unthreaded spacers tailored to your exact application needs—all proudly crafted right here in the USA. Whether you need to connect, separate, or position critical components in your assemblies, these essential fasteners are engineered to deliver unmatched reliability under tough conditions.

The perfect finishing touch that also means business! AMPG's heavy-duty stainless steel acorn nuts provide a rock-solid connection AND neatly cover those exposed threads for a clean, protected assembly. Built to last with premium stainless steel.

AMPG in Indianapolis is taking our machining capabilities to the next level with the arrival of our second multi-spindle machine: the high-performance INDEX MS 22-8. Faster turnarounds on hard-to-find specialty fasteners and high-precision components—without compromising on exact tolerances or lead times.

We’re proud to keep pushing boundaries and delivering on our promise: Beautiful Parts, Right Now.

Unlike standard off-the-shelf options that are mass cold-formed, every AMPG hex nut is meticulously machined from solid bar stock. When your project demands non-standard thread sizes, specialty alloys, or corrosion-resistant materials that local hardware stores simply don't carry, AMPG delivers.

AMPG’s socket head screws feature an internal drive system that saves crucial space while eliminating the need for bulky external tools—delivering a cleaner, more streamlined look for any project. Whether you need standard, high, low, or ultra-low profiles, you can get the exact fit for your application crafted in beautiful, high-performance brass.

Need to convert thread sizes or switch thread types seamlessly? Our Male-Female Threaded Hex Thread Adapters are engineered to give you complete flexibility when adapting your fasteners. Whether you need maximum corrosion resistance or standard high-strength steel, we offer these versatile adapters in 18-8 Stainless Steel, 316 Stainless Steel, Lightweight Aluminum, Heavy-Duty Steel, and Black Oxide Steel to match your exact specs.

Behind every high-performance component is a machinist who refuses to compromise on quality. At AMPG, we bridge the gap between initial schematics and flawless ex*****on. We specialize in the hard-to-source and the hard-to-make—delivering exact-spec custom parts and fasteners.

Also known as C Washers, these Easy On Slotted Washers are clever little time-savers feature a handy side slot that lets you slide them in or pop them out without tearing down your entire setup. Whether you are making quick adjustments on the job site, doing routine maintenance, or just trying to save your sanity on a complex build, they get the job done in seconds.

Uncompromising strength where it matters most. AMPG’s 4140 steel shoulder bolts are precision-engineered to strict tolerances, delivering maximum reliability for high-stress industrial applications.

Big news on our shop floor! We just took delivery of our second brand-new Multi-spindle CNC machine, and this one is extra special—it’s an INDEX Corporation MS 22-8 model, and it happens to be the very last one available in the entire country!

Adding another high-performance multi-spindle machine to our lineup means we can produce our hard-to-find fasteners faster than ever before. It’s a total game-changer for machining challenging, high-temp alloys like A286 Stainless Steel with extreme precision and speed. We’re constantly investing in top-tier technology so our customers get the exact standard and custom fasteners they need, right when they need them.
