Simpson Strong-Tie THD50400H - Titen HD Concrete Screw Anchor (Zinc) 1/2" x 4" 20ct

The Titen HD anchor is a patented, high strength screw for concrete and masonry. It is design for cracked and uncracked concrete; a requirement that the 2009 IBC places on post-installed anchors. The self-cutting, non-expansion characteristics of the Titen HD anchor make it ideal for structural applications, even at reduced edge distances and spacings. Recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications.
