Read previous reviews about poor quality and durability before buying. These nuts are amazing. I have worked with cars and trucks for almost 40 years and the 1989 F150 only needed 4 replacement nuts but they were at such a good price. I bought a full set of 20 pieces! They arrived in 2 days, they are as strong and durable as the original OEM nuts the truck already has and have a nice appearance. Highly recommended. At this price you can't go wrong! Will buy again, no questions asked! Bruce in Philadelphia!
