Frequently Asked Questions

What base materials is the Titen HD THD37212CS approved for use in?

The Titen HD heavy-duty screw anchor is designed for use in cracked and uncracked concrete as well as masonry substrates, making it suitable for a wide range of structural anchoring applications.

Can the Titen HD countersunk anchor be used outdoors permanently?

No. Because the THD37212CS is zinc plated carbon steel, it is not recommended for permanent exterior use or highly corrosive environments. It is suitable for dry, interior, noncorrosive environments or temporary outdoor applications only.

Does the countersunk head style offer any advantage over a standard hex head anchor?

Yes. The countersunk head allows for flush-mount applications that are not possible with a hex head, and countersinking also leaves a cleaner surface appearance for exposed through-set applications where a low-profile finish is required.

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 moved in the future.
