At Vattanaporn Screw(1991) Co., Ltd. , we specialize in the production of OEM screws and bespoke products. Our screws can be plated in various colors to fulfill our customers' specific requirements. We ensure the quality of each plating color adheres to Japanese and European standards by conducting corrosion resistance tests against rust. The Salt Spray Test method is employed to guarantee the screws meet our customers' expectations for rust resistance. Additionally, we manage the chemicals and storage for each screw color in accordance with RoHS and REACH regulations to align with European standards. Our Screw Baking service is also available to mitigate steel stress and minimize the risk of Hydrogen Embrittlement in customer applications.
