The NT65A5M 16-Gauge Pro Straight Finish Nailer has been redeveloped from our classic NT65A3. It can drive 16-gauge straight finish nails ranging from 1-1/2 in. to 2-1/2 in. in length. NT65A5M not only provides exceptional durability but also prevents jams and allows for fewer reloads. It's equipped with our unmatched cylinder valve drive system, which not only provides increased durability but also gives it the quickest response and driving speed. The 360-degree adjustable hook helps keep the tool at hand at all times.
