ASME B18.16.6 Prevailing Torque Hex Nut Manufacturer | All Metal Lock Nut
LONGZE high-performance ASME B18.16.6 Prevailing Torque Hex Nuts (All-Metal Type) are precision-engineered for high-temperature and high-stress industrial environments. As a core element of the LONGZE GFM-WCR System, these nuts utilize top-deflection locking technology to ensure consistent prevailing torque without the use of non-metallic inserts. Our manufacturing ensures strict adherence to ASME B18.16.6 specifications, providing exceptional vibration resistance for heavy machinery, structural, and energy sector applications.
Optimal factory-direct assembly for imperial high-vibration environments:
- 🔹 Primary Bolt: ASME B18.2.1 | DIN 931 / 933 | ISO 4014 / 4017
- 🔹 Standard Washer: ASME B18.22.1 | DIN 125 | ISO 7089

🛡️ LONGZE STRATEGIC RISK MANAGEMENT & RESILIENCE
- Locking Risk: ASME B18.16.6 first and fifth removal torque verification.
- Material Risk: Proof load testing per ASTM A563 / ISO 898-2 requirements.
- Thermal Risk: All-metal integrity check for high-temperature stability.
- Compliance Risk: ISO 3269 inspection and chemical substance safety.
- Material Buffer: Strategic inventory of high-grade alloy and carbon steel.
- Volume Ready: Automated high-speed tapping and deflection assembly lines.
- Redundancy: Certified secondary heat treatment partners per ISO standards.
- Transparency: Batch-coded traceability from steel coil to final inspection.
Quality Guarantee: Any deviation from the signed TDS or PI is subject to 100% replacement after verification. We guarantee locking performance for every batch.
Secure Shipping: Moisture-resistant packaging and photographic evidence of loading provided for every container to ensure cargo arrives intact.
ASME & ISO Technical FQA
A: While ASME B18.16.6 covers imperial dimensions and specific deflection types, ISO 7042 is the metric counterpart for all-metal prevailing torque nuts. Both focus on high-vibration security.
A: Per ASME B18.16.6 и ISO 2320, they are designed to maintain locking torque for up to 5 cycles. For safety-critical joints, fresh installation is always recommended.
