印度采购需求：紧固件、干壁螺钉、SDS、自攻螺钉、自钻螺钉、刨花板螺钉

I'm looking to source self-tapping screws for an upcoming project. Specifically, I need screws that are reliable and suitable for various applications. It would be great if you could provide details on the materials used, sizes available, and your pricing structure. Additionally, I'm interested in knowing the minimum order quantity, lead times for production, and any options you might have for bulk purchasing. If you have samples or a catalog to share, that would really help in making a decision. Looking forward to your response!
