Working With Wood Screws - Common Sense Tips
Use soap or wax to lubricate screws in hardwoods.
Keep brass screw heads from twisting off. Use the same size steel screw to thread the wood, then insert the brass screw.
Your screwdriver bit is less likely to slip when you use Phillips or Robertson (Square Head) style screws.
Use a drill with an adjustable chuck clutch to avoid stripping screw heads.
Drilling pilot holes prevents your wood from splitting, and allows for a tighter joint.
