Bostitch 16-Gauge Crown Stapler
Score: 78/100Rankings

The Bostitch 651S5 is a heavy-duty pneumatic stapler designed for construction applications like sheathing and siding. It features high drive power and tool-free maintenance, making it reliable for tough jobs. However, its weight and limited staple length range make it less ideal for prolonged overhead work or longer fasteners.

The NuMax SFL618 is a pneumatic 3-in-1 flooring nailer/stapler designed for installing tongue-and-groove hardwood flooring up to 3/4" thick. It features an aluminum housing and interchangeable no-mar base plates, though it suffers from high air consumption and a semi-quick jam release. It is best suited for DIY homeowners and contractors needing multi-purpose functionality for flooring installation.
