Custom Plastic Screw Manufacturing
Unlike mass-produced molded fasteners, our CNC-machined plastic screws are engineered for specific mechanical requirements. We machine custom threads, head styles, and drive types in materials ranging from standard acetal to high-performance PEEK.
If your application requires non-conductive, chemically resistant, or lightweight hardware that standard catalog components cannot provide, our machining process ensures the exact specifications for your assembly.
Custom Threads
Machined thread profiles matched to your assembly torque and engagement requirements.
Head Styles
Pan, flat, socket, and custom geometries produced to drawing.
Drive Types
Slotted, Phillips, hex, Torx, and application-specific drive configurations.
Functional Grades
Non-conductive, chemically resistant, and lightweight hardware options.
Engineering Plastics and High-Performance Polymers
Selecting the right material is critical for the success of your machined components. We maintain a comprehensive inventory of engineering plastics suitable for demanding environments.
Standard Engineering Plastics
POM (Acetal), Nylon (PA6/PA66), HDPE, UHMW-PE, and ABS.
High-Performance Polymers
PEEK, PPS, PEI (Ultem), PSU, and PPSU.
Fluoropolymers
PTFE and PVDF for extreme chemical resistance.
Specialized Grades
Antistatic, conductive, glass-filled, and flame-retardant versions machined to specific functional requirements.
Our Machining Capabilities
We utilize multi-axis CNC milling and turning centers to produce complex geometries that go beyond simple fasteners.
CNC Turning
Ideal for screws, bushings, rollers, and cylindrical components requiring concentricity.
CNC Milling
Used for complex housings, brackets, jigs, and fixtures with intricate features.
Secondary Operations
Precise drilling, tapping, threading, slotting, and surface finishing to ensure your parts are assembly-ready upon arrival.
Why Engineers Choose CNC Over Molding
For low-to-medium volume production and prototyping, CNC machining offers distinct advantages over injection molding. There are no expensive mold tooling costs, allowing for design iterations without the risk of high capital investment.
We provide the flexibility to modify designs quickly, ensuring your parts meet the exact tolerance requirements of your mechanical assembly before moving to larger production runs.
CNC Machining
- No mold tooling investment
- Fast design iterations
- Ideal for low-to-medium volumes
- Prototyping to production
Injection Molding
- High capital tooling costs
- Longer change cycles
- Best for high volumes
- Design locked by mold
