I'm looking to source all types of fasteners for our upcoming projects. We need a diverse range, including bolts, nuts, screws, and washers. Please provide detailed info on your product offerings, including specifications, materials, and any available grades. Additionally, I'd like to know about your pricing, minimum order quantities, lead times, and whether you offer samples for testing. If you have a catalog or product list, that would be great too. Looking forward to your prompt response!
