Nails are more permanent, but they're also more likely to bend vs. break. Common nails are suitable for most general construction, whereas box nails, brad nails and finishing nails have a thinner shank and less likely to split thinner wood. Drywall nails, flooring nails and roofing nails are task-specific and essential to a successful project. Staples, screw eyes and fastener strips are also available for more specialized tasks.
