Screw Anchors, Stainless Steel, Simpson Strong-Tie Titen HD®

Heavy-duty screw anchors built for harsh, corrosive environments. Builders Stainless stocks the Simpson Strong-Tie Titen HD® screw anchor in 304 and 316 stainless steel for coastal, marine, and high-moisture construction where carbon-steel anchors corrode and fail. The Titen HD installs in concrete or grout-filled masonry with no separate expansion sleeve — the anchor cuts its own threads as it drives.

304 vs. 316 Stainless Titen HD: Which Should You Use?

Choose 316 stainless Titen HD for coastal, marine, and chloride-exposed work — docks, seawalls, pools, and salt-air structures — where added molybdenum resists pitting and crevice corrosion. Choose 304 stainless for general exterior and high-moisture use without direct salt exposure. For St. Augustine and Florida coastal projects, 316 is the standard choice.

Key Features

• Code-listed for cracked and uncracked concrete per IAPMO UES ER-493 (stainless)
• Code-listed for masonry per ICC-ES ESR-1056
• Qualified for static and seismic loading (Seismic Design Categories A–F)
• One-piece screw anchor — no separate expansion sleeve or setting tool
• Installs with an impact wrench or hand tool; hole size equals anchor size
• Available in 304 and 316 stainless, 3/8" through 3/4" diameter
• Tested per ACI 355.2 and AC193

How to Install a Titen HD Screw Anchor

1. Drill a hole the same diameter as the anchor using a carbide bit (per ANSI B212.15) to the specified depth, then blow it clean with compressed air. (Overhead holes need not be blown clean.)
2. Insert the anchor through the fixture and into the hole.
3. Drive the anchor with an impact wrench until the hex-washer head seats against the fixture.

Frequently Asked Questions

What is the difference between a Titen HD and a wedge anchor?

A Titen HD is a screw anchor that cuts its own threads into the base material and can be removed, with no expansion sleeve. A wedge anchor expands against the hole wall and is permanent. Titen HD installs faster and works in concrete and grout-filled masonry; wedge anchors suit fixed structural concrete connections.

Is the stainless Titen HD code-approved for coastal construction?

Yes. The stainless Titen HD is code-listed under IAPMO UES ER-493 for cracked and uncracked concrete and ICC-ES ESR-1056 for masonry. The 316 stainless version is recommended for salt-water, marine, and chloride-exposed environments where standard carbon-steel anchors corrode.

What size Titen HD do I need?

Anchor diameter and embedment depth depend on the load and base material. Stainless Titen HD anchors run from 3/8" through 3/4" diameter in a range of lengths. Larger diameters and deeper embedment carry higher loads. Consult the ER-493 load tables for your specific application.
