5-3. Nail Selection The Model NR 90GC utilizes D-head (clipped head) nails collated with paper tape. Applicable nail dimensions are shown below. Please note that screw-type nails cannot be used with the Model NR 90GC. CAUTION: Ensure that nails are as specified in Fig. 1. The Model NR 90GC utilizes D-head (clipped head) nails collated at an angle of 35 degrees which are the same as the nails utilized by P. However, some D-head nails made by other makers are collated at a different angle of 26 degrees. Use of such nails will cause clogging of nails and subsequent damage to the nailer. Also avoid use of misaligned nails or nails collated with a weak paper tape. Do not use P's 2" Roundrive nail (eccentric full round head nail) with the Model NR 90GC because it may cause bending of nails.
