Hi Bill, Good Day! Thank you for your purchase. We sell Aftermarket products. Aftermarket products can be any part of a vehicle that is not sourced directly from the car's maker. These parts are direct replacement parts, designed to function the same, may not be physically identical to the original, but there are some instances that it even worked better than the OE parts. These items are just copied from the original which definitely have their pros and cons. Hence, we will definitely relay your comments about the product to our supplier so we can address the issue on quality. Thank you for pointing this out to us. As to the nuts, our part will require you to use the OE hardware, if you no longer have the hardware you may simply get it at your local auto store. Would you like us to send you a replacement for the part or would you like to return the part for refund? We have sent you an email to better assist you with your concern. Thank you.
