Simpson Strong Tie THDB62100H Washer Concrete Screw Anchor

Description

Product Overview

The Simpson Strong‑Tie THDB62100H is a 5/8 inch by 10 inch hex‑washer screw anchor designed specifically for demanding concrete and masonry applications. Constructed from high‑strength steel and finished with a zinc‑plated coating, this anchor delivers exceptional durability and corrosion resistance in dry interior environments. The specialized thread geometry undercuts the base material, creating a secure mechanical lock that transfers loads efficiently and reduces the risk of pull‑out under dynamic forces. Each anchor is precision‑machined to meet ANSI standards, ensuring consistent performance across a wide range of installation conditions.

With a hex‑washer head, the anchor provides a clean, flush finish that eliminates the need for additional washers or caps, simplifying the installation process and improving the aesthetic of the final assembly. The washer also distributes load more evenly across the fastening surface, reducing stress concentrations and extending the service life of both the anchor and the attached component. This product is part of Simpson Strong‑Tie’s Titen HD line, a series renowned for its heavy‑duty capabilities and reliability in both cracked and uncracked substrates.

Technical specifications include a package dimension of 12.52 x 3.78 x 3.54 inches and a weight of 10.02 pounds per pack of ten anchors. The product was first made available on June 22, 2020, and has since earned a solid reputation among contractors and DIY enthusiasts alike. Its design accommodates standard ANSI tolerance drill bits, eliminating the need for specialized tools or proprietary drill bit sets, which translates to lower overall project costs and faster installation times.

In addition to its mechanical strengths, the THDB62100H anchor is engineered for ease of use. The hex‑washer head can be driven with a standard impact driver or wrench, allowing installers to achieve the required torque without excessive effort. The zinc plating not only protects against rust but also provides a smooth surface that resists snagging on surrounding materials during installation. This combination of strength, durability, and user‑friendly design makes the THDB62100H a versatile choice for a variety of structural fastening needs.

Whether you are anchoring sill plates for new construction, securing ledger boards for deck extensions, or installing post bases for fence systems, the THDB62100H offers a reliable solution that meets or exceeds industry standards. Its proven performance in both residential and commercial settings underscores its suitability for projects that demand long‑term stability and safety.

Usage

This anchor excels in applications where a strong, permanent connection to concrete or masonry is required. Typical use cases include attaching sill plates to foundation walls, fastening ledger boards for decks and porches, and securing post bases for fencing or railing systems. The anchor’s ability to perform in both cracked and uncracked substrates provides flexibility for renovation projects where existing concrete may have minor imperfections.

For interior dry environments, the zinc‑plated finish offers sufficient corrosion protection, making the THDB62100H an ideal choice for residential framing, commercial interior partitions, and light‑industrial installations. The anchor can also be employed in utility installations such as conduit supports, where a secure, load‑bearing connection is essential.

Installation requires drilling a pilot hole to the recommended depth using a standard ANSI‑tolerance drill bit. After cleaning the hole of dust and debris, the anchor is inserted and driven until the hex‑washer head sits flush with the surface. The design eliminates the need for additional washers, reducing material costs and simplifying the overall assembly process.

Because the anchor is compatible with standard impact drivers and wrenches, it can be installed quickly on job sites with limited tool inventories. This efficiency is especially valuable in time‑sensitive projects, such as fast‑track construction schedules or retrofit installations where downtime must be minimized.

FAQ

What size drill bit should I use for the THDB62100H anchor?

The recommended pilot hole size is 5/8 inch (approximately 16 mm). Using a drill bit within the ANSI tolerance range ensures the anchor threads engage properly while allowing the hex‑washer head to sit flush.

Can this anchor be used in exterior applications?

While the zinc‑plated finish offers good corrosion resistance for interior dry conditions, for exterior or high‑humidity environments we recommend a stainless‑steel or hot‑dip galvanized variant to provide enhanced protection against the elements.

Is the THDB62100H suitable for attaching heavy loads?

Yes. The heavy‑duty design, combined with the optimized thread geometry and high‑strength steel construction, allows the anchor to support substantial loads typical of sill plates, ledger boards, and post bases in residential and light commercial projects.

How many anchors come in a pack?

Each package contains ten (10) THDB62100H anchors, providing enough units for most standard framing and anchoring tasks while offering bulk purchasing convenience.

What warranty does Simpson Strong‑Tie provide for this product?

Simpson Strong‑Tie offers a limited warranty that covers material defects and performance issues under normal use conditions. For detailed warranty terms, consult the product documentation or contact our customer service team.
