Simpson Strong-Tie THD50400H 1/2 Inch x 4 Inch, Hex Washer Head, Zinc Plated Titen HD Heavy-Duty Screw Anchor for Concrete, Easy Installation (Pack of 20)

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.
