I'm interested in sourcing custom thumb screws for a new product I'm developing. I've been selling on Amazon for over a decade and want to ensure I get high-quality components. I'm specifically looking for anodized aluminum thumb screws featuring a specific thread size and length. Could you provide me with details on your pricing, minimum order quantities, and lead times? Additionally, any information on customization options and bulk discounts would be greatly appreciated. Looking forward to your response!
