  • How do you choose the right size drill bit?

    Use a bit 1/64” smaller than the target hole size for softwoods. Use a bit exactly the same size as the hole when working on other materials. If you're not sure which to select, choose a drill bit 1/64” larger than the hole you wish to create. This will account for variables such a wood density and screw type.
  • What drill bit to use for steel?

    Cobalt (HSCO) is considered an upgrade from HSS because it includes 5-8% Cobalt blended into the base material. This is a great option for drilling into harder steel as well as stainless steel grades. Carbide (Carb) is the hardest and most brittle of the drill bit materials.

  • Is a screw stronger than a nail?

    Your normal wood screws are not structural. While undoubtedly considerably stronger than normal screws, this leads me to still question their shear resistance. In the end: nails, hex bolts, and lag bolts are still better in most applications. Structural screws are just easier than bolting and cooler than nailing.
  • What is the difference between a screw and a nail?

    Difference Between Nails and Screws. Since a screw has threads, you can not use a hammer, you need a screwdriver or some tool that turns the screw into the material. Hence that is why on the top of a nail, the head is flat, while the screw has a dimple for a philips, flat head or another type of tool to do the turning.

  • Do I need to drill a hole for a self tapping screw?

    The sharp-tipped screws are designed for drilling their own hole into softer materials such as wood and plastic so they don't need a pilot hole. For thicker metal, it may require more than one screw to drill through the surface. To save time and labor, you can use self-drilling self-tapping screws to drill into metal.
