Many of the projects you undertake in your home require some sort of hardware or fasteners. While many items you purchase, such as coat racks, shelving systems and ready-to-assemble furniture will come with the required hardware, there are a million other projects where you may need a fastener: nuts, bolts, screws, and washers. Selecting the proper hardware for your project or fix is crucial to getting the job done properly.
