Product Description
The Simpson Strong-Tie Titen HD 1/4 in. x 1-7/8 in. Zinc-Plated Countersunk Head Heavy-Duty Screw Anchor (Model No. THDB25178CS) sets the standard for high-performance anchoring and ease of installation in cracked and uncracked concrete as well as masonry. Engineered by Simpson Strong-Tie, this carbon steel screw anchor delivers industry-leading performance even in seismic and wind-governed conditions, making it a trusted choice for structural and general anchoring applications in dry, interior, noncorrosive environments or temporary outdoor use. The countersunk head design enables a flush-mount profile, providing a cleaner surface appearance for exposed through-set applications where a hex head is not suitable.

Frequently Asked Questions
- Do I need a special drill bit to install the Titen HD THDB25178CS 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 - 1/4 in. - so no oversized or specialty bit is needed.
- Can the Titen HD countersunk anchor be used outdoors or in corrosive environments?
- The THDB25178CS is zinc plated carbon steel and is not recommended for permanent exterior use or highly corrosive environments. It is designed for dry, interior, noncorrosive environments or temporary outdoor applications only. For long-lasting corrosion resistance, a Type 316 stainless-steel Titen HD option is available.
- Is the Titen HD screw anchor removable after installation?
- Yes. The Titen HD is removable, making it ideal for temporary anchoring or applications where fixtures may need to be repositioned or removed at a later time.
- Why does the Titen HD use a countersunk head instead of a hex head?
- The countersunk head style allows for flush-mount applications that are not possible with a hex head. This design leaves a cleaner surface appearance for exposed through-set applications and accommodates situations where a low-profile or flush finish is required. The T30 6-lobe drive further eases installation and is less prone to stripping than traditional recessed anchor heads.
