Description
Product Overview
The Simpson Strong‑Tie THDB25312CS is a heavy‑duty concrete screw anchor engineered for demanding structural applications. Constructed from carbon steel with a zinc exterior finish, it offers superior strength and corrosion resistance. The flat, countersunk head provides a flush finish, while the 1/4‑inch (0.25″) fully threaded shank and 3.5‑inch length deliver deep embedment in concrete. Certified to ANSI standards, this anchor meets both static and seismic loading requirements, making it suitable for a wide range of construction projects.
Usage
Ideal for anchoring fixtures, equipment, and structural components in concrete slabs, walls, and footings. Engineers and contractors use these anchors for permanent installations as well as temporary setups where removal may be required. The design eliminates the need for special drill bits, allowing use of standard ANSI‑tolerance drills, which streamlines on‑site installation and reduces labor time.

FAQ
What concrete strength is required for installation?
The anchor is rated for use in concrete with a compressive strength of 3000 psi or higher, which covers most standard residential and commercial applications.
Can I reuse the anchor after removal?
Yes, the anchor is designed to be removable and can be re‑installed, provided the hole remains undamaged and the anchor is not over‑tightened.
Do I need a special drill bit?
No special drill bit is required. Use a standard 1/4‑inch ANSI‑tolerance drill bit to create the pilot hole.
Is this anchor suitable for seismic zones?
Absolutely. The anchor is qualified for both static and seismic loading conditions, meeting relevant industry standards for seismic applications.
How many anchors are included per package?
Each package contains 50 heavy‑duty screw anchors, providing ample quantity for medium‑scale projects.
