ASME B18.21.1 Helical Spring Lock Washer Manufacturer | Inch Split Lock Washer | Helical Spring Washer | GFM-WCR System
ASME B18.21.1 Helical Spring Lock Washer Manufacturer
LONGZE premium ASME B18.21.1 Helical Spring Lock Washers are engineered to provide critical tension and anti-vibration resistance for high-performance industrial assemblies. As a functional pillar of the LONGZE Engineered Fastening System, these split lock washers utilize trapezoidal wire sections to apply reactive spring force, effectively preventing bolt loosening under dynamic loads. Manufactured from high-grade carbon steel or stainless steel, our spring washers ensure consistent elastic recovery and long-term joint integrity.
Optimal factory-direct assembly for vibration-sensitive environments:
- 🔹 Bolt: ASME B18.2.1 / Grade 5 / Grade 8 Bolts
- 🔹 Plain Washer: ASME B18.22.1 / ISO 7089
- 🔹 Hex Nut: ASME B18.2.2 / Nylon Insert Lock Nuts

🛡️ LONGZE STRATEGIC RISK MANAGEMENT & RESILIENCE
Advanced mitigation protocols designed to protect global procurement chains from technical and chemical failures (HE).
- Hydrogen Embrittlement (HE): Mandatory baking protocols for electroplated high-carbon spring steel.
- Decarburization Risk: Controlled atmosphere heat treatment to maintain surface hardness and spring life.
- Fatigue Risk: Wire section verification to prevent premature splitting or "flatting" under torque.
- Logistics Risk: Heavy-duty reinforced woven bags for high-density palletizing (up to 1,000kg per unit).
- Raw Material Buffer: Strategic safety stock of SAE 1060/1070 carbon steel and SUS 304/316 wire.
- Rapid Production: Automated helical forming and cutting lines for multi-million piece monthly output.
- Compliance: Full chemical analysis and mechanical property certificates provided with every batch.
- Global Freight: Optimized DDP/CIF solutions for strategic ports including Istanbul, Houston, and Klang.

Quality Assurance & Global Logistics Risk Control
Our dual-protection framework transforms international procurement risks into manageable engineering variables through strict legal compliance and transparent logistics evidence.
Q: What if the spring washers suffer from brittleness or premature failure?
A: Quality is our red line. Any deviation from the signed ASME B18.21.1 TDS or PI is subject to 100% replacement after internal verification. We sell engineered security, not just metal.
Q: How do you ensure high-tonnage shipments remain secure during long-haul shipping?
A: We employ reinforced palletizing with high-resolution loading evidence. Every container is sealed with unique IDs to ensure your supply chain remains transparent and intact from Handan to your doorstep.
