Drawing-based / OEM / Non-standard Precision Custom Nuts & Special Threaded Parts

• Thread Class & Gauging

Internal threads precision-tapped to 6H, 4H5H, or 2B/3B classes. 100% verified using calibrated Go/No-Go plug gauges.

• Face Squareness

Critical control of the bearing surface squareness relative to the thread axis (typically within 0.02mm) to prevent uneven loading and bolt fatigue.

• Custom Locking Mechanisms

Options for All-metal Prevailing Torque(staked or crimped),Nylon Inserts, or Serrated Bearing Surfaces for superior anti-loosening performance.

• Thin-Wall Integrity

Specialized CNC turning for thin-walled custom nuts, ensuring no structural deformation during the tapping or heat treatment process.

• Internal Chamfering

Double-sided countersinking to facilitate easy lead-in for automated bolt insertion.

Precision Protection

For nuts with high surface requirements (e.g., polished or plated), we provide individual tray packaging or vacuum sealing to prevent friction and oxidation.

Bulk Packaging

Standard export cartons (Max 25kg) on fumigation-free pallets, secured with moisture-proof stretch wrap.

Thread Accuracy

Every batch is verified using precision Go/No-go gauges and thread micrometers to ensure a perfect fit.

MTR (EN 10204 3.1)

Full material chemical analysis and mechanical property reports provided for every order.

Certification

ISO 9001:2015 certified factory; products compliant with RoHS and REACH environmental standards.
