Key Features

Built for Corrosive Jobs

Type 316 stainless steel makes this anchor a smart choice for exterior work, saltwater exposure, and chemical-heavy environments where standard fasteners do not hold up long term.

Fast Concrete Installation

The self-undercutting, non-expansion thread design cuts into concrete and masonry for efficient installation with a standard-size drill bit, so setup stays simple on the job.

Titen HD Holding Power

This Simpson Strong-Tie heavy-duty screw anchor is made for concrete and masonry fastening where you want a clean hex-washer head installation without a separate washer.

Overview

Simpson Strong-Tie Titen HD 1/4-in. x 2-in. Type 316 Stainless-Steel Heavy-Duty Screw Anchor

The Simpson Strong-Tie Titen HD 1/4-in. x 2-in. Type 316 Stainless-Steel Heavy-Duty Screw Anchor is a concrete and masonry anchor built for demanding fastening in corrosive environments. This is a heavy-duty screw anchor designed for fastening fixtures into concrete and masonry. Model Number THDC25200H6SS. For contractors handling exterior mechanical, electrical, and plumbing work, railings, ledgers, or other exposed attachments, this anchor gives you stainless corrosion resistance with the quick installation that makes screw anchors practical on real jobsites.

What matters here is the combination of Type 316 stainless steel body material and the Titen HD thread design. Simpson positions Type 316 as the better choice for salt water, chemical exposure, and other aggressive environments where lesser materials can become the weak link. The thread design undercuts the base material to transfer load efficiently, and the anchor is non-expansion, which helps when you need a heavy-duty concrete anchor that installs without the extra steps tied to some other anchoring systems.

For installation, this anchor keeps things straightforward. The 1/4 inch anchor uses a 1/4 inch carbide drill bit, and Simpson states no special drill bit is required as long as you are using standard-sized ANSI tolerance drill bits. After drilling the hole and cleaning it, you insert the anchor through the fixture and tighten it until the hex-washer head contacts the fixture. It can be installed with an impact wrench or by hand tool, which gives crews some flexibility depending on access, speed, and base material conditions.

Design details are what separate a good anchor from one that wastes time. This Titen HD anchor uses a hex-washer head, so you get a clean installed look without needing a separate washer. The cutting thread design is meant to bite efficiently into the base material during installation. Supplementary product data also calls out serrated cutting teeth and a self-undercutting profile, which helps explain why this anchor is favored for faster installs in concrete and masonry compared to more complicated anchor types.

On the job, the real value is where this anchor can be used. Simpson lists it for exterior or corrosive environments and specifically ties the stainless version to saltwater and chemically exposed applications. If you are fastening steel, treated lumber, railing posts, or MEP supports in places where moisture and corrosion are constant concerns, the material choice matters just as much as load performance. This anchor is also listed as qualified for static and seismic loading conditions in the supplementary Tool Nut data, which makes it relevant for more demanding specified work.

There are a few important practical notes. The recommended steel fixture hole size for this 1/4 inch anchor is 3/8 inch to 7/16 inch, and the wrench size is 3/8 inch. Simpson also states these anchors are one-time-use only, because repeated installation can wear the threads and reduce load capacity. Hole quality matters too. Oversized holes in the base material can reduce or eliminate mechanical interlock, so this is one of those products where following the drilling guidance is not optional if you want the published performance.

This specific THDC25200H6SS configuration is the 1/4 inch by 2 inch version in a 50-pack. That makes it a solid fit for crews that need multiple anchors for a small run of installations without jumping to bulk carton quantities. One footnote from Simpson is worth knowing up front: Model THDC25200H6SS does not meet minimum embedment in the code report. That does not make it useless, but it does mean spec-driven buyers need to confirm the embedment and approval requirements for the exact application before ordering.

Who should buy it? This anchor makes the most sense for contractors and serious DIY users working in concrete or masonry where corrosion resistance is not negotiable. If you are doing general exterior fastening in mild conditions, you may not need Type 316. But if the job is near the coast, around water treatment, exposed to deicing salts, or around corrosive chemicals, this stainless Titen HD concrete anchor is the right kind of overbuild.

Made for Exterior Concrete Fastening

If you are mounting lumber or hardware to concrete outdoors, this is where the Titen HD makes sense. It is built to go in fast while giving you the corrosion resistance that exposed installations demand.

• Designed for concrete and masonry applications
• Type 316 stainless steel is suited for exterior and corrosive environments

Handles Tough Exposure Better

The stainless version earns its keep where ordinary anchors are more likely to become the failure point. Near water, salt, or chemical exposure, material choice is not a small detail.

• Type 316 stainless steel is the preferred option for saltwater and corrosive conditions
• Ideal for railings, exterior structural attachments, and exposed fastening points

Thread Design That Speeds Up Installs

The geometry of the anchor is the whole story here. The undercutting thread profile is made to tap into the base material efficiently, which helps crews move faster without switching to a more complicated anchor system.

• Self-undercutting, non-expansion screw anchor design
• Hex-washer head provides a clean installed appearance without a separate washer

Pro Tip

Drill the hole with the same diameter carbide bit, give the hole enough depth for dust to settle, and clean it out before driving the anchor. Also, do not back it out and reuse it later. Simpson calls this a one-time-use anchor, and worn threads mean less holding power.

Tool Nut’s Take

Tool Nut’s Take

The right anchor when corrosion is the real problem

The Simpson Strong-Tie Titen HD 1/4-in. x 2-in. Type 316 Stainless-Steel Heavy-Duty Screw Anchor is the kind of fastener you buy when you do not want to revisit the job because the environment beat up the hardware.

• Who it’s for: Contractors fastening into concrete or masonry outdoors, especially around water, salt, or chemical exposure.
• Why it stands out: You get the speed and simplicity of a screw anchor with Type 316 stainless steel and a thread design that is made to cut and hold in concrete.
• Worth knowing: This is a 50-pack, one-time-use anchor, and Simpson specifically notes that model THDC25200H6SS does not meet minimum embedment in the code report, so spec jobs need a quick check before you commit.

Common Questions

• What base materials is this anchor designed for? It is designed for concrete and masonry applications.
• What drill bit size does this model require? The THDC25200H6SS uses a 1/4 inch carbide drill bit, which matches the anchor diameter.
• Can this anchor be used in corrosive environments? Yes. Simpson identifies the Type 316 stainless steel version as ideal for exterior and corrosive environments, including saltwater and chemically exposed locations.
• Can I reinstall the same anchor if I remove it? No. Simpson states the Titen HD screw anchor is for one-time use only because repeated installation can wear the threads and reduce load capacity.
• What wrench size fits this anchor? This 1/4 inch model uses a 3/8 inch wrench size.
