Yes DEWALT will sell a comprehensive range of nails. Speak to your local stockist, or DEWALT office for the range of nails offered in your market. DEWALT would always recommend that you use the DEWALT nails with the tool, however if for whatever reason these are not available to you we would recommend other EC5 classified paper tape collated framing nails as per the tool specifications. Use of other brand EC5 classified nails would not invalidate the tool warranty unless that nail resulted in nail feed issues, jamming of the firing mechanism or accelerated wear of the nail feed or firing components.
