Each set contains 25 bolts and 25 U-nut clips (50 pieces in total), providing you with all the accessories you need for repair or assembly projects. The body fender bolts and U-nut clips are coated with black phosphate for excellent corrosion resistance and durability, ensuring long-lasting use even in harsh conditions. The 1/4 bolts are designed with hexagon head and free-rotating washers for quick and easy installation while ensuring a secure hold. Insert the U-nut clip into the mounting holes of the part to be secured (such as a fender, bumper, or furniture panel), align the bolt with the threaded hole in the U-nut clip, gently screw it in, and tighten the bolt. These body fender bolts and U-nut clips are widely used in automotive repair, including bumper, fender and hood repair. They are also suitable for furniture assembly and other general fastening needs.
