1) Allowable Loads have been increased 60% for wind or seismic loads; no further increase shall be permitted.
2) The allowable loads for bolts are based on parallel-to-grain loading with 3" minimum member thickness, except HPA which
requires a 3-1/2" thick wood member.
3) Allowable loads are based on the use of either nails or bolts; nail and bolt values cannot be combined.
4) 16d sinkers or 10d common nails may be substituted for the specified 16d common nails at 0.85 of the table loads.
5) Minimum nail penetration is 1-5/8" for 16d nails.
6) For alternate nail schedule and load values consult USP.
7) Minimum quantity of fasteners to be installed. Product may have additional fastener holes not needed to meet published allowable load of product.
8)
NAILS:
10d x 1-1/2" nails are 0.148˝ dia. x 1-1/2" long, 16d nails are 0.162" dia. x 3-1/2" long.

Installation:
• Use all specied fasteners. See Product Notes, page 17.
• Minimum concrete strength is 2,500 psi.
• The allowable loads for bolts are based on parallel to grain
loading with a 3" minimum member thickness, except the
HPA which requires a 3-1⁄2" thick wood member. Reduce
load per code requirements when minimum member
thickness is not achieved.
• Minimum concrete edge distance is 4" for PA & PAI series,
and 6" for HPA series.
• Minimum concrete block edge distance is 20".
• Designer may specify alternate fastening schedules. Refer
to Nail Specication Table on page 20 for nail shear values.
Load values shall not exceed published allowable loads.
• No anchor bolts are needed for achieving efcient stress
transfer from framing to concrete walls or foundations.
• Bolts must be ordered separately. See page 24 for available sizes.
