Question: what is the difference between 16 gauge and 18 gauge nailer?
Answer: The common gauge sizes for nailers are 15, 16 & 18. Simply put, the higher the gauge number, the thinner the nail. The number stands for how many nails per inch. For example, an 18 gauge would have 18 pieces per inch which are going to be thinner than 16 gauge nails, which would have 16 nails per inch.
