ISO 10511 Nylon Insert Locking Cap Nuts (Acorn Locking Nuts)
LONGZE ISO 10511 Nylon Insert Cap Nuts combine the aesthetic protection of a dome (acorn) nut with the vibration-resistant security of a prevailing torque locking mechanism. As a specialized safety node in the LONGZE GFM-WCR System, these nuts utilize a non-metallic insert to create frictional interference, preventing loosening under dynamic loads while shielding bolt threads from corrosion and accidental contact. Ideal for automotive, medical equipment, and high-end machinery, our ISO 10511 series represents the intersection of safety engineering and industrial finish.
Optimal factory-direct assembly for vibration-prone protected joints:
- 🔹 Primary Match: ISO 4017 Bolts / ISO 7380 Button Heads
- 🔹 Standard Locking: ISO 7040 / DIN 985
- 🔹 Standard Cap Nut: DIN 1587 / DIN 917

🛡️ LONGZE STRATEGIC RISK MANAGEMENT & RESILIENCE
Specialized risk control for critical locking applications where vibration and thread protection are non-negotiable.
- Locking Failure: Real-time monitoring of nylon insert hardness ensures consistent prevailing torque.
- Dome Detachment: Automated welding/pressing control prevents cap separation under torque load.
- Thermal Risk: High-temperature nylon (Green/Blue) available for engine-room applications.
- Aesthetic Protection: Plastic-capped tooling prevents tool marks on decorative dome surfaces.
- Batch Consistency: Every 500 units undergo a functional torque test to anchor the GFM-WCR data.
- Material Selection: Cold-heading grade carbon steel ensures the hex body maintains grade strength.
- Global Logistics: Expert packing for air-freight and DDP shipments to Southeast Asia and Europe.
- Custom Branding: Head marking or custom dome engravings available for OEM clients.

Quality Assurance & Global Logistics Risk Control
Transforming technical locking requirements into secure global supply chains through the LONGZE GFM-WCR framework.
Q: What if the nylon insert fails to lock upon first assembly?
A: Performance is our red line. All ISO 10511 nuts must meet the minimum prevailing torque defined in ISO 2320. Any failure triggers immediate batch isolation and replacement. We guarantee the lock.
Q: How do you prevent surface scratches on high-mirror cap nuts?
A: We utilize individual poly-bagging or specialized cellular trays for high-finish orders. Palletized shipments are double-wrapped to ensure they arrive in "showroom" condition for our international clients.
