Designed for attaching picket fences to the fence frame. Unfortunately, once driven in, these nails leave an excessive amount of plastic on the nail head, making them very unsightly and unsuitable for a fence or any other outdoor project that needs to be aesthetically pleasing. I will not scrape plastic from 2000+ nail heads! Update: Went to HD and bought the Grip-Rite brand. Much better . Virtually no plastic is left on the nail head and they are cheaper!
