Custom Fasteners
Resolute Precision Manufacturing (RPM) is a direct-from-manufacturer custom fastener manufacturer. We produce custom CNC turned fasteners, including screws, bolts, nuts, inserts, bushings, fittings, flanges, and shafts, on Swiss CNC machines and bar-fed lathes. Every one of our custom machined fasteners is made to your drawing, in your specified material, in quantities from prototype to high-volume production. No broker. No distributor. Direct pricing from the shop that makes them.
Request a QuoteWhy Source Custom Fasteners Direct?
Standard catalog fasteners are available from any distributor. Custom fasteners, meaning non-standard thread forms, unusual drive features, special materials, close-tolerance shanks, or proprietary geometry, need a machine shop that understands both the machining process and the functional requirements of your application. Special fasteners like these are hard to source from catalogs, and a middleman rarely understands the drawing well enough to catch problems early.
Resolute Precision Manufacturing specializes in exactly this work. As a custom fastener supplier, we run Swiss CNC machines and bar-fed lathes configured for efficient production of turned fasteners from 3/8 inch to 3.2 inches in diameter, in lot sizes from a few hundred prototype pieces to hundreds of thousands of production parts per year. And because we sell direct, the price you pay is the price from the machines that make your parts, not a distribution margin added on top.

Leading CNC Turning for Custom Fasteners
Our CNC turning fasteners programs run on Swiss and bar-fed lathes with live tooling, so threads, drive features, cross holes, and flats are all machined in a single setup. That keeps head-to-shank concentricity tight, cuts handling, and shortens lead times. Customers choose us for leading CNC turning for custom fasteners that must meet exact thread, drive, and material requirements, from the first prototype to the millionth part.
Custom Screw Machining on Swiss and Bar-Fed Lathes
For small, high-precision parts, custom Swiss screw machining is hard to beat. Our Swiss CNC machines support the bar right at the cutting tool with a guide bushing, which gives excellent concentricity and surface finish on slender, small-diameter parts. Our custom screw machining capability covers everything from custom machine screws and precision shoulder bolts to complete custom screw machine parts with threads, drive features, and cross holes.
We make CNC turning precision screws for applications from miniature electronics hardware to heavy structural fasteners. If you are looking for CNC machining screws for sale in non-catalog specifications, you can order directly from us in any quantity, from a prototype lot to full production.
The Breadth of Our Custom Fastener Capability
Our bar-fed setup accepts bar stock from 3/8 inch to 3.2 inches in diameter and up to 12 feet long. Automatic bar feeders maintain continuous production with minimal operator intervention, and robotic loading is available on select cells for unattended overnight runs. For larger chucked workpieces, our turning centers handle diameters up to 25.5 inches and lengths up to 44 inches.
Beyond fasteners, we make custom machined parts such as dowel pins, bosses, bushings, and shafts on the same equipment, so your whole assembly can come from one supplier.
Special Fasteners Precision Machining
Special fasteners precision machining is where a shop’s process control shows. Our special fasteners precision machining work includes non-standard thread forms and pitches, close-tolerance shanks, proprietary head geometry, and unusual drive profiles, all produced with live tooling and checked against your drawing. We machine CNC fasteners in stainless steel, brass, aluminum, titanium, and alloy steel, so you can match the material to your strength, weight, and corrosion requirements.
Custom Fastener Services and Capabilities
Our custom fastener services cover the full path from drawing to delivered parts:
- Prototype runs: quick-turn samples so you can test fit and function before committing to volume
- Production runs: repeatable, bar-fed production of custom screw machine parts from hundreds to 500,000+ parts per year
- Precision screws: CNC turning precision screws with accurate threads, drive features, and tight-tolerance shanks
- Custom machined parts: dowel pins, bosses, bushings, and shafts made alongside your fasteners
- Thread and drive options: standard and custom threads, plus hex, Torx, Phillips, slotted, hex socket, and custom drive profiles
- Material selection: guidance on the best alloy or plastic for your application
- Direct engineering contact: one team from quote to delivery, with no distributor in between
Custom Fastener Applications
Resolute Precision Manufacturing custom fasteners and CNC fasteners serve applications across industries where standard catalog fasteners do not meet the design requirement:
- Aerospace and defense: non-standard thread forms, titanium and stainless alloy fasteners to drawing
- Medical devices: ultra-clean implant fasteners in 316L stainless or titanium Grade 5
- Automotive: specialty fasteners for under-hood, powertrain, and chassis assemblies
- Fluid power: threaded inserts, fitting bodies, and valve mounting hardware in brass and stainless
- Industrial machinery: custom shoulder bolts, precision dowel pins, specialty studs, and custom machined nuts
- Electronics: non-magnetic stainless fasteners, aluminum standoffs, and PCB spacers

Frequently Asked Questions
A custom fastener differs from catalog stock in one or more of these ways: non-standard thread form or pitch; unusual drive feature geometry; special material or heat treat; close-tolerance shank diameter; proprietary head geometry; or a combination of standard features in a non-catalog configuration.
Yes. We produce fasteners to ASME B18.2.1, B18.3, B18.6.3, SAE, and other industry standards where the drawing references them. We also produce fully custom fasteners to customer-proprietary drawings.
Our Swiss CNC machines handle parts from approximately 1mm diameter. In practical terms, we regularly produce #0-80 and M1.0 threaded fasteners on our Swiss machines.
Yes. If you provide a physical sample, we can measure and document the geometry and produce a drawing for quoting. This is common for legacy fasteners where the original drawing is unavailable.
