- Guide holes are in place for fastener installation efficiency. The number of fasteners are determine by the designer.
- Attachment to studs is made with up to 27 #12 screw or nails symmetrically placed.
- StiffClip TD resists vertical uplift loads.
- Allowable loads for steel framing have not been increased for wind loads, seismic loads, or other factors.
- Allowable shear for nails and screws is increased 60% for wind and seismic loads in wood framing.
- I30
- For wood, moisture content > 19%. Consult The Steel Network, Inc. for reductions to values.
