Fasteners drive into wood, metal, concrete, fiberglass and other construction and fabrication materials to complete the final product. They come in a variety of materials and finishes for many different applications, such as stainless steel for rust resistance.
Nails drive into your project via blunt force to hold two or more layers together. Nails remove easily for projects that require occasional reworking. Power fasteners fit into nail guns that drive them into the material with no effort on your part short of pulling the trigger. A power nail comes in special strips or rolls; a single nail is incompatible with power nailers. Specialty nail uses include trim, roofing and carpentry.
Screws use threads along their body to offer the strongest hold of any fastener. If your job calls for screws in concrete or similar materials, you can use a drill bit to create a pilot hole or a special tapper screw designed to drive right into concrete. Screw applications call for specific types, so make sure that you have the correct fastener for your application, such as a countersunk screw for wood or a metal fastener for machinery or sheet metal. If your job calls for hanging something heavy from a screw, you should get screw anchors to add strength to the screw hold, especially in drywall or other soft materials.
Staples fit into staple guns or tack hammers and apply very quickly. They typically have short legs and work best with thin material such as upholstery or roofing paper. Since staples have two legs, you can connect two pieces together at a joint with just one fastener.
Fasteners work hard to bind your project together. Make sure that you've got the most heavy-duty fastener for your job to ensure that its quality construction lasts a lifetime.
