Use and selection
This family is identified by a hex head and an extended No.5 drill point for steel-frame and fabrication enquiries. Record the individual steel thicknesses, gaps and required screw dimensions on the connection detail. The table lists nominal diameter and length ranges; neither those lengths nor the No.5 designation gives a verified drill-through thickness or load rating.

| Nominal diameter | Length range / mm |
