Frequently Asked Questions

AI
304 stainless steel offers superior corrosion resistance, making it ideal for outdoor or humid environments. Carbon steel bolts are generally stronger and cheaper but require coating or painting to prevent rust, making them suitable for indoor or dry applications.
Most modern machinery, bicycles, and European products use metric sizing (e.g., M3, M4, M5). Using imperial bolts can lead to incorrect threading and loose fittings. Always verify your equipment's specifications before purchasing a kit to ensure compatibility.
Yes, a storage box is highly recommended. Hex bolt kits contain many small, similar-looking pieces. A compartmentalized box keeps sizes organized, prevents loss, and protects the threads from damage, saving time during repairs and extending the kit's lifespan.
