Six engineered fastening platforms, each cold-forged in-house and qualified to automotive-grade specifications — from lightweight aluminum bolts to micro fasteners and thread inserts.
Purpose-built for lightweighting, the ZT68 platform replaces steel fasteners with up to 65% weight savings while holding automotive-grade strength — a one-piece flange design cold-forged in a single flow for consistent clamp and corrosion resistance.
Why choose it: one-piece flange + anodized corrosion protection mean predictable clamp and no galvanic pairing worries.
| Specification | Value |
|---|---|
| Tensile strength | ≈ 630 MPa |
| Yield strength | ≈ 500 MPa |
| Elongation | ≥ 8% |
| Temperature stability | Stable up to 150°C |
| Weight saving vs. steel | Up to 65% |
| Friction coefficient | 0.09 – 0.15 (controlled) |
| Head design | One-piece flange, cold-forged |
| Corrosion resistance | Anti-galvanic; anodized, passes 60-day neutral salt spray |
Our rivet-nut family provides clean, high-clamp threads on blind sides and thin panels — installed from one side in about 3 seconds. Multiple head styles and a sealing-ring variant make it the fastening of choice for new-energy, appliance and structural applications.
Why choose it: a single-sided, 3-second install replaces welding and tapping on thin panels — with a sealing option for battery joints.
| Feature | Detail |
|---|---|
| Installation | Single-side blind riveting, ≈ 3 seconds |
| Applications | Thin panels, closed profiles, multi-material stacks |
| Head styles | Flat, half-hex, full-hex, anti-slip / knurled |
| Materials | Steel, stainless (304 series) and more |
| New-energy option | Sealing-ring design for sealed battery/body joints |
For the parts consumers never see but always feel, our micro screws deliver repeatable torque, clean thread forms and a full plating range — manufactured at high volume with up to 12 secondary operations per screw.
Why choose it: repeatable torque and a complete plating range protect the feel and finish of high-end consumer hardware.
| Specification | Detail |
|---|---|
| Thread range | M0.5 – M2 |
| Secondary operations | Up to 12 per screw |
| Drive types | Cross, hexalobular (Torx-style), slot, one-way |
| Thread forms | Machine thread, self-tapping thread |
| Plating | Zinc, tri-color zinc, zinc-nickel |
Restore stripped threads and reinforce light-alloy holes with our wire thread inserts — manufactured to national and military standards with free-running and locking styles for demanding assemblies.
Why choose it: military-standard strength (≥1370 MPa) restores and reinforces threads in aluminum and light alloys.
| Specification | Detail |
|---|---|
| Hardness | HRC 43 – 50 |
| Min. tensile strength | ≥ 1370 MPa |
| Thread range | M2 – M39 |
| Length / diameter | 1D – 5D |
| Standards | GB/T 24425.1-2009, GJB 119.4A-2001 |
| Materials | SUS304, SUS316 (stainless) |
| Styles | With / without tang, free-running or locking |
Multi-station cold-formed aluminum sleeves with near-net shape and superior grain flow — produced with high material utilization and up to 12 precision finishing operations for consistent, lightweight structural components.
Why choose it: near-net cold forming saves material and delivers superior grain flow for lightweight structural parts.
| Feature | Detail |
|---|---|
| Process | Multi-station cold forming |
| Geometry | Near-net shape, excellent grain flow |
| Material utilization | High (material-efficient) |
| Finishing | Up to 12 precision machining operations |
Custom-specified inserts and embedded nuts with external knurling and internal threads — engineered around your exact application, across multiple materials, for reliable anchoring in plastics, aluminum and sheet metal.
Why choose it: external knurling locks the insert into place — engineered around your exact geometry and material.
| Feature | Detail |
|---|---|
| Customization | Custom-specified dimensions & threads |
| Retention | External knurling for secure anchoring |
| Materials | Multi-material options |
| Applications | Plastics, aluminum, sheet-metal assemblies |
