Assembly Services
Resolute Precision Manufacturing assembles machined components with purchased hardware bearings, seals, o-rings, fasteners, springs, and inserts into sub-assemblies and complete assemblies ready for installation in your product. We also kit machined parts with hardware components for your assembly team. Receive an assembled component instead of a box of individual parts. Request a QuoteWhy Outsource Assembly to Your Machine Shop?
There is a straightforward logic to having your machine shop assemble the components it produces. The people who made the parts know their geometry, their tolerances, and their fit requirements better than any separate assembly shop. When a machined part needs to press-fit into a housing, thread into a body, or seal against an o-ring, the machinist who produced it to those specifications is the best person to perform the assembly.
The practical business case is equally straightforward: one purchase order to RPM covers both machining and assembly. One supplier relationship. One accountability. One delivery of a completed sub-assembly rather than multiple shipments of individual components to your assembly department.
Our Services
Assembly Capability at RPM
Our assembly services cover a range of standard operations performed in our facility:
Threaded hardware installation — fasteners, inserts, studs, and threaded components torqued to specification
Press-fit assembly — bearings, bushings, and interference-fit components installed with controlled press force
Seal and O-ring installation — elastomeric seals and O-rings installed in grooves without cutting or damage
Spring and clip installation — retaining rings, snap rings, and spring elements installed to drawing
Kitting — machined parts packaged with hardware components in kit form for customer assembly line use
Sub-assembly inspection — dimensional and functional checks on assembled components before shipment

Assembly Program Benefits
Manufacturers who move assembly to Resolute Precision report these consistent benefits:
- Reduced assembly line touchpoints — your team receives an assembled unit, not loose components
- Fewer purchased part number transactions — RPM procures hardware on your behalf
- Improved quality — parts are assembled by the team that made them to their exact specifications
- Shortened internal lead time — components arrive ready to install, not ready to be assembled first
Frequently Asked Questions
Can RPM source purchased hardware components for assembly?
Yes. We procure standard hardware fasteners, bearings, seals, o-rings, retaining rings, and springs through our purchasing network and include them in the assembled delivery. You receive one invoice that covers machined parts and hardware.
What torque specifications does RPM use for threaded hardware?
We torque threaded hardware to customer-specified torque values documented on your drawing or assembly specification. We use calibrated torque tools and record torque values on assembly traveler documentation.
Does RPM perform functional testing of assembled components?
Dimensional and fit verification are standard on our assembled components. Functional testing pressure testing, leak testing, rotation torque is available on a project-specific basis. Contact us with your assembly specification to discuss testing requirements.
How does RPM handle assembly of sensitive components that could be damaged?
Our assembly team is trained on proper handling of precision machined components, including protection of machined surfaces, proper seal installation tools, and controlled press-fit procedures. Parts are cleaned before assembly and protected during packaging for shipment.
