Frequently Asked Questions
How do I stop deck screws from rusting?
Choose corrosion-resistant materials (stainless steel for the harshest environments) or high-quality coated carbon-steel screws tested for outdoor exposure. Keep fasteners dry where possible, avoid mixing dissimilar metals with your deck framing, and use coatings or sealants recommended for your deck material.
Why do screws strip when I drive them in, and how do I prevent it?
Stripping happens when the driver slips out of the head under torque. Use star/Torx-drive screws and a properly sized bit (magnetic bits help), maintain steady pressure while driving, and use an adjustable clutch on your drill to avoid over-torque. Pre-drilling a pilot hole for very hard woods also reduces resistance and the risk of stripping.
Can I use self-tapping screws without pre-drilling?
Self-tapping screws are designed to cut their own mating thread and often remove the need for pilot holes in softwoods and treated lumber. For dense hardwoods or where splitting is a concern, pre-drilling a pilot hole is still recommended to ensure correct alignment and prevent wood damage.
