Screw Anchors, 304 Stainless Steel, Simpson Strong-Tie Titen HD®

Titen HD 304 Stainless Steel Screw Anchors are available in a range of sizes for medium to heavy-duty anchoring. They are engineered for fast, secure fastening in solid masonry and concrete. Easy to install — drill, drive, and tighten — while offering excellent corrosion resistance.

Titen HD® 304 stainless steel screw anchors deliver fast, high-strength anchoring in solid concrete and grout-filled masonry. The Titen HD cuts its own threads as it drives — no separate expansion sleeve or setting tool — and the 304 stainless body resists corrosion in exterior and high-moisture conditions. Available here in 3/8", 1/2", and 5/8" diameters for medium to heavy-duty fastening.

Choosing a 304 Titen HD Size

Larger diameters carry higher tension and shear loads and require deeper embedment. A 3/8" Titen HD suits light fixtures, conduit, and brackets; 1/2" handles ledgers, plates, and general structural fastening; 5/8" covers heavy structural connections and higher-load applications. Match anchor diameter and embedment depth to your load and base material.

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 — installs with an impact wrench, hole size equals anchor size
  • Removable and reusable; no expansion force against the hole wall
  • 304 stainless steel for exterior and corrosive-environment durability
  • 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 size Titen HD do I need?

Anchor diameter and embedment depth depend on the load and base material. A 3/8" Titen HD suits light to medium fixtures; 1/2" handles general structural fastening; 5/8" carries heavy structural loads. Larger diameters and deeper embedment provide higher capacity. Consult the IAPMO ER-493 load tables for your application.

Should I use 304 or 316 stainless Titen HD?

Use 304 stainless Titen HD for general exterior and high-moisture applications without direct salt exposure. For coastal, marine, or chloride-rich environments, step up to 316 stainless, which adds molybdenum for greater resistance to pitting and crevice corrosion. For St. Augustine coastal work, 316 is the safer choice.

Can a Titen HD be removed and reused?

Yes. Unlike a wedge anchor, the Titen HD is a screw anchor that can be backed out and removed. It can often be reinstalled if the threads it cut remain intact, though for structural connections a fresh anchor in an undamaged hole is recommended for full rated capacity.
