Decide on which screw head works best for your project, including slotted, Phillips and square drives. A combination slotted-head wood screw can cause power-driven screwdrivers to cam-out. Phillips head screws work better, but the purpose of Phillips screws is to make the bit cam-out at a particular point to avoid over-torque. The square, or Roberts drive, mitigates the cam-out issue and transfer the greatest amount of torque.
For some home improvement project and other applications, the specifications may require the use of cooper screws or some other type of copper fastener. For copper roofing and copper flashing, copper screws are the right choice because it provides an attractive solution that is long-lasting and very eco-friendly.
Discuss your fastener needs with your copper screws supplier. Your vendor should have an extensive range of copper screws for sale, as well as other screws, bolts, nuts and washers for your upcoming project.
If you are considering the use of copper screws, make sure that the fasteners are appropriate for the project. Case in point, copper wood screws are superior to nails for fastening down decking and other uses. However, copper screws may not be suitable for framing and structural applications, such as attaching joists (metal connectors).
Increasingly, more manufacturers are bringing structural copper screws and other structural fasteners solutions to the marketplace. However, most building code books address the minimum requirements for nail fasteners.
