印度采购需求：紧固件、石膏板螺丝、SDS螺丝、自攻螺丝、自钻螺丝、刨花板螺丝

I'm looking to source drywall screws for an upcoming project. Specifically, I need information on your product range, including screw sizes, head types, and any special features you may offer. Additionally, could you provide your pricing structure, minimum order quantities, and lead times for delivery? Understanding your quality standards and any certifications would also be helpful as we evaluate our options. Thanks!
