The Simpson Titen HD 3/8 in. x 3 in. Type 316 Stainless Steel Countersunk Head Heavy-Duty Screw Anchor by Simpson Strong-Tie sets the standard for high-performance anchoring in demanding environments. Engineered for use in cracked and uncracked concrete as well as masonry, this Type 316 stainless-steel anchor delivers severe-level corrosion resistance for long-lasting reliability in harsh or corrosive conditions. The countersunk head design enables a flush-mount profile for clean, low-profile installations, while the T50 6-lobe drive system ensures easier driving with fewer cam-outs. With industry-leading performance qualified for both static and seismic loading conditions, this heavy-duty screw anchor is a top choice for structural and architectural applications where durability and precision matter.

Frequently Asked Questions

What type of environments is the Titen HD Type 316 Stainless Steel anchor designed for?

The Titen HD Type 316 Stainless Steel screw anchor is engineered to provide severe-level corrosion resistance, making it well suited for harsh, corrosive, or moisture-exposed environments where long-lasting performance is required. This distinguishes it from the standard carbon steel Titen HD, which is designed for dry, interior, noncorrosive environments or temporary outdoor applications.

Do I need a special drill bit to install this anchor?

No special drill bit is required. The Titen HD is designed to install using standard-sized ANSI tolerance drill bits. The hole size is the same as the anchor size - 3/8 in. - so no upsizing or specialty tooling is needed. A driver bit is also included in each box.

Why choose a countersunk head style over a hex head?

The countersunk head style is specifically designed for applications that require a flush-mount profile. Unlike a hex head, the countersunk head sits flush with or below the surface of the fixture, providing a cleaner surface appearance for exposed through-set applications and enabling installations where a protruding head is not acceptable.

Is this anchor suitable for seismic applications?

Yes. The Titen HD is qualified for both static and seismic loading conditions, and it offers industry-leading performance even in seismic and wind-governed conditions, making it appropriate for use in regions or projects with seismic design requirements.
