Durable nails for the GNB 18V-38 Professional, for optimal fastening in concrete Bosch collated concrete nails are designed for use with the GNB18V-38 cordless 18V Concrete Nailer. Ideal for framing, the fasteners attach metal tracks to concrete. The Bosch 18V concrete nailer comes with both a 22-shot collated magazine (an extra-capacity magazine, which can hold up to 44 collated pins, is sold separately), and a single shot nose piece. The nails and the GNB18V-38 Concrete Nailer were tested and certified together (ICC). The cordless nailer is an ideal replacement for gas-powered concrete nailers, because it eliminates the need for consumable gas cartridges. The easy-to-use depth adjustment uses an intuitive sliding switch. The nails are available in five different lengths, from 16mm to 38mm Wide array of nails with different lengths for multiple fastening applications Tool and nails from a single source – optimised and certified system (with the GNB 18V-38 Professional)
