Featuring SENCO’s Neverlube® oil-free design, the tool never needs to be lubricated, eliminating stains to the work surface. SENCO’s 2” 21-gauge pinner is capable of shooting 5/8” to 2” slight head pins. The 21-gauge offers more holding power than a 23-gauge tool and leaves a smaller hole than an 18-gauge brad nailer, creating the perfect middle ground between the two.
