Simpson Strong Tie THD50500H 1/2″ x 5″ Washer Concrete Screw Anchor

Description

Product Overview

The Simpson Strong‑Tie THD50500H is a 1/2 inch by 5 inch heavy‑duty concrete screw anchor designed for demanding structural applications. Featuring a hex‑washer head, the anchor provides a clean, flush finish after installation, eliminating the need for additional washers or caps. Each screw is zinc‑plated, delivering superior corrosion resistance in dry interior environments and extending the service life of the fastener. The thread profile is engineered to undercut the base material, creating a secure mechanical lock that transfers loads efficiently. With a pack of 20 anchors, the product offers a cost‑effective solution for large‑scale projects while maintaining consistent performance across each unit. The anchors meet ANSI standards for concrete fasteners and are compatible with standard drill bits, simplifying the installation process for both seasoned professionals and DIY enthusiasts.

Usage

These anchors excel in a variety of construction and renovation scenarios. They are ideal for attaching sill plates, ledger boards, post bases, and other structural members to both cracked and uncracked concrete or masonry substrates. The hex‑washer head design allows for a neat appearance in exposed applications, such as interior framing or decorative installations. Because the anchor can be driven with standard ANSI‑tolerance drill bits, contractors can use existing toolsets without investing in specialized equipment. The product is also suitable for retrofitting older structures where additional reinforcement is required, providing a reliable connection point that meets modern building codes. Whether you are building a new deck, securing a load‑bearing wall, or installing a heavy piece of equipment, the THD50500H delivers the strength and durability needed for long‑term performance.
