ROUND NAILS
Fit D-Head Nailers
RoundStrip nails are full-round-head nails that are designed to work in clipped-head pneumatic nailers from most major manufacturers. The nails have all of the benefits of a regular framing nail, but are collated at a 34° angle. A slightly offset head allows the nails to be densely packed, shank-to-shank in the magazine, allowing for twice as many nails to be driven between reloads. The nails conform to all national and regional building codes related to the use of round-head nails in framing and sheathing, the maker says. SENCO Products Inc.; 800-543-4596; www.senco.com
