Our buyer received a letter from your company regarding an order I put in for some 3” stainless steel U-Bolts. I just wanted to thank you for the kind letter and let you know that your U-Bolts have been completely invaluable to us. We use them in the manufacturing process of an extremely sensitive product. Our previous U-bolts were zinc plated, therefore they became rusted too easily and risked the quality of the product. We hadn’t been able to find another U-bolt supplier with our specific size requirements (without going custom) until I came across your website! We are very grateful for the quality product you have sent us. We will definitely continue to use your company and the services provided.
