The Milwaukee® Collated Duplex Nails are intended for temporary fastening of timber, for applications such as concrete formwork, bracing, or scaffolding assembly. These duplex nails have a large top nail head and an increased spacing between nail heads to make it easier to pry the nails out of material. The nails feature a durable plastic collation material to stand up to the rigors of the jobsite.
