The Titen HD heavy-duty screw anchor family of products set the standard for high-performance anchoring and ease of installation. The Titen HD (carbon steel) is designed for use in dry, interior, noncorrosive environments or temporary outdoor applications, while the Titen HD Type 316 stainless-steel option offers you long-lasting corrosion resistance for unsurpassed peace of mind. Titen HD offers industry-leading performance even in seismic and wind-governed conditions. The countersunk head style is for applications that require a flush-mount profile. Countersinking also leaves a cleaner surface appearance for exposed through-set applications. The anchor head’s 6-lobe drive eases driving and is less prone to stripping than traditional recessed anchor heads. Titen HD® 3/8 in. x 2-1/2 in.
