Simpson Strong-Tie Titen HD® 3/8" 316 stainless steel screw anchors, available in 3", 4", 5", and 6" lengths. The Titen HD cuts its own threads into concrete or grout-filled masonry — no expansion sleeve or setting tool — and marine-grade 316 stainless gives maximum corrosion resistance in salt-water and coastal exposure. The 3/8" diameter handles medium-duty brackets, railing posts, and fixtures.

Choosing a 3/8" Titen HD Length

Anchor length must cover your fixture thickness plus the required embedment into the base material. Shorter 3" and 4" anchors suit thinner fixtures and standard embedment; 5" and 6" anchors allow thicker fixtures or deeper embedment for higher load capacity. Always confirm the minimum embedment for your load against the ER-493 tables.

Key Features

  • 3/8" diameter, 316 stainless steel — maximum corrosion resistance for salt-water and marine environments
  • 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
  • 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 (3/8") using a carbide bit per ANSI B212.15, to the specified depth. 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 length 3/8" Titen HD do I need?

Choose a length that covers your fixture thickness plus the required embedment depth into concrete or masonry. A 3/8" Titen HD comes in 3", 4", 5", and 6" lengths. Longer anchors allow deeper embedment and higher load capacity. Consult the IAPMO ER-493 tables for the minimum embedment your load requires.

Why choose 316 stainless over 304 for this anchor?

316 stainless steel contains molybdenum, giving superior resistance to pitting and crevice corrosion from chlorides and salt water. For coastal, marine, dock, and pool environments, 316 is the recommended grade; 304 suits general exterior use without direct salt exposure. For St. Augustine coastal work, 316 is the standard.

What is the 3/8" Titen HD used for?

The 3/8" Titen HD anchors medium-duty connections into concrete or masonry: railing posts, brackets, ledgers, gates, and equipment. It offers higher load capacity than the 1/4" size while installing quickly with an impact wrench, and the 316 stainless body withstands corrosive coastal and marine conditions.
