I'm reaching out to get detailed information and pricing for your range of fasteners. We're looking at potentially placing a significant order, so it would be great to understand the different types you offer, including specifications, materials, and any available options or variations. Additionally, if you could include lead times for production and shipping, along with any bulk pricing discounts you might have, that would be super helpful. Please let me know if you need any further details from my side to provide a comprehensive quote. Thanks!
