Choose MYWISH for fasteners that are built to last. Our Hex Flange Serrated Bolts and Nuts Sets are the go-to solution for high-stress and vibration-prone applications. Unlike standard bolts, the integrated flange distributes the load over a wider area, while the serrations act as an automatic lock washer, ensuring a secure hold without loosening over time. Each bolt and nut is forged from 304 Grade Stainless Steel (18-8), providing exceptional protection against corrosion and rust in wet, outdoor, or marine environments. Trust MYWISH bolts for critical connections, from securing DIY outdoor furniture to maintaining heavy machinery. Note: 304 stainless steel is inherently non-magnetic but may show weak magnetism after cold-working (stamping/forming). This is normal and does not affect the corrosion resistance. Keep all small parts out of reach of children under 6 years old.
