Anchoring and Fastening Systems for Concrete and Masonry Addendum
PDPA .300" Headed Fasteners with .157" Shank Diameter
Simpson Strong-Tie Anchor Systems has added several
new lengths to the PDPA line of pins. PDPA pins are
speciically designed for fastening into A36 and A572
structural steel and extra-hard concrete. The fasteners
are compatible with several Simpson Strong-Tie ®
powder-actuated tools and other major-brand poweractuated
tools. The .157" shank diameter and special
heat treating results in a strong and ductile pin.

1. The entire pointed portion of the fastener must penetrate through the steel to obtain the
tabulated values, unless otherwise indicated in footnote 4, 5, 6 or 7.
2. The allowable tension and shear values are for the fastener only. Members connected to
the steel must be investigated separately in accordance with accepted design criteria.
3. Steel strength must comply with the minimum requirements of ASTM A 36 (Fy = 36 ksi,
Fu = 58 ksi) or ASTM A 572, Grade 50 (Fy = 50 ksi, Fu = 65 ksi).
