英国采购需求：螺母，尼龙锁紧螺母

I'm reaching out to request pricing information for stainless steel A2 nylon lock nuts, specifically for sizes ranging from M3 to M20. I'm looking to order a mixed lot of approximately one ton. It would be great if you could provide a comprehensive price list for these items. Additionally, I'd like to know the estimated shipping costs to the United Kingdom. Clear details on both the pricing and delivery would be greatly appreciated. Looking forward to your prompt response!
