Precision Custom Screw Machining & Threaded Components
Stop compromising on thread integrity and lead times. We leverage advanced multi-axis CNC lathes and Swiss-type machines to deliver flawless, high-precision fasteners. From micro-screws to heavy-duty custom bolts, we handle tough alloys, tight tolerances, and complete secondary operations under one roof.
- ✓ Extreme Precision: Tight tolerances down to ±0.005mm with perfect concentricity.
- ✓ Tough-Material Expertise: Flawless cutting of Titanium, Stainless Steel (SS316/304), Inconel, and PEEK.
- ✓ Turnkey Operations: Fully integrated thread rolling, heat treatment, and anti-loosening pre-coating (Loctite/Precote).
Advanced Custom Screw Machining & Multi-Axis Turning
Zonclair offers turnkey manufacturing for standard and non-standard fasteners. Driven by specialized Swiss-type lathes and multi-tasking CNC turning centers, our **custom screw machining** services deliver continuous accuracy for tight-tolerance, complex-profile threaded components.
- ✓ Processing Range: Outer diameters ranging from Ø0.5mm to Ø32mm via Swiss Screw Machining, and up to Ø250mm via Conventional Chuck Turning.
- ✓ Thread Standards: Full coverage for Metric (M), Unified (UNC/UNF), British Standard (BSW/BSF), and custom Acme threads.
- ✓ Tolerances Level: Linear dimensional tolerance to ±0.005mm; Thread fit complies strictly with 4H / 6g classes.
- ✓ Machining Complexity: Live-tooling enables integrated cross-milling, axial drilling, tapping, and slotting in a single automated setup.
Rigid Custom Screw Machining Quality Control & Metrology
Thread integrity is non-negotiable at Zonclair. We back our precision **custom screw machining** with an advanced in-house metrology lab to eliminate thread stripping, pitch deviation, and assembly failures, ensuring every custom fastener fits flawlessly into your system.
- ✓ 100% In-house Gauging: Every threaded batch undergoes rigid testing using calibrated Go / No-Go Thread Plug & Ring Gauges.
- ✓ ZEISS SPECTRUM CMM Verification: We leverage the ZEISS SPECTRUM Bridge-type Coordinate Measuring Machine to inspect critical dimensions, geometric tolerances, and axial alignment with trusted results.
- ✓ Profile & Pitch Metrology: High-magnification optical comparators and toolmaker microscopes verify thread crests, roots, and pitch angles.
- ✓ Full Material Traceability: First Article Inspection (FAI) reports and certified Material Test Reports (MTR) are available upon request.
