Custom Drawing Non-Standard Fasteners Shipped To Large Siberian Energy Holding Group
Our production workshop completed a long-term bulk order of custom non-standard fasteners manufactured under exclusive engineering drawings for a major energy group in Western Siberia. This hardware is designed for thermal generator assembly and pipeline joints operating under continuous high temperature and cyclic load fluctuations. Our technical team optimized the part structure in advance to simplify mass production without reducing long-term service performance.
Core Features Of This Custom Fastener Batch
- Extended shank bolts with special head geometry for narrow confined installation space
- Alloy steel raw material with enhanced thermal fatigue resistance for long heat cycle service
- Heat-resistant anti-corrosion coating rated for continuous working temperature up to 450℃
- Matched supporting accessories: heat insulating flat washers and nylon locking nuts for anti-vibration protection
