In my earlier review (and related Q&A submission), which I see no way to update or remove, I blamed quality control for my inability to thread the galvanized nuts onto the galvanized bolts. As it turns out, an employee at my local TSC accidentally mixed non-galvanized (grade 5?) nuts into the bin, which under store lighting appear virtually indistinguishable from the galvanized nuts (black vs. dark gray). After sifting through the bin, I found enough galvanized nuts to complete my project and encouraged the store manager to address the issue in hopes of saving other customers from the inconvenience I endured. All of the galvanized nuts thread perfectly onto all of the galvanized bolts and the thick coating inspires confidence that the product will hold up well to the elements. I regret my earlier review (which I hope can be removed so its two stars don't drag down the rating) and wish to set the record straight that I have no complaints about the product!
