I'm looking to purchase a specific type of channel bush for our upcoming project, made from high-quality Stainless Steel SS 316. The required specifications are an outer diameter of 18 mm, an inner diameter of 10 mm, and a precise thickness of 7 mm. Accuracy in the thickness is crucial for our application, so I'd appreciate your assurance on this detail. Could you please provide a quotation for 13,000 pieces? Additionally, it would be helpful to know the lead time for production and shipping, as well as any bulk order discounts that may apply. Looking forward to your prompt response so we can proceed efficiently.
