委内瑞拉采购需求：螺栓、螺母、螺钉、垫圈、锚栓、螺纹杆

I'm looking for information on Inconel bolts for a current project. Specifically, I need to know about the different specifications you offer, including sizes, strength ratings, and any relevant certifications. Additionally, please provide details on pricing, minimum order quantities, and lead times. If there are any volume discounts or special offers available, I'd love to hear about those too. Looking forward to your prompt response!
