I'm reaching out to request a detailed quotation for 1,000 units of a specific type of fastener that includes a hanger bolt, along with EPDM washers and flange nuts. Please include information on pricing, lead time, and any minimum order requirements you might have. Additionally, I would appreciate insights on bulk pricing and whether there are any discounts for larger quantities. It would also be helpful to know about the materials used and the availability of these components. If you have a catalog or datasheet that outlines specifications and options, please share that as well. Looking forward to your prompt response!
