Screw Anchors, 304 Stainless Steel, 1/2” Diameter Simpson Strong-Tie Titen HD® – Available Lengths

Simpson Strong-Tie Titen HD® 1/2" 304 stainless steel screw anchors, available in 3", 4", 5", 6", and 8" lengths. The Titen HD cuts its own threads into concrete or grout-filled masonry — no expansion sleeve or setting tool — and the 304 stainless body resists corrosion in exterior and high-moisture conditions. The 1/2" diameter handles heavier structural loads than smaller sizes.

Also available in other diameters: 3/8", 1/2" (this page), and 5/8". See all sizes in the 304 Stainless Titen HD hub.

Choosing a 1/2" 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", 6", and 8" 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

• 1/2" diameter, 304 stainless steel — ideal for exterior and corrosive 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 (1/2") 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 1/2" Titen HD do I need?

Choose a length that covers your fixture thickness plus the required embedment depth into concrete or masonry. A 1/2" Titen HD comes in 3", 4", 5", 6", and 8" lengths. Longer anchors allow deeper embedment and higher load capacity. Consult the IAPMO ER-493 tables for the minimum embedment your load requires.

How much load can a 1/2" Titen HD hold?

Allowable tension and shear loads depend on embedment depth, concrete strength, edge distance, and spacing. The 1/2" diameter carries higher loads than 3/8" anchors, making it suited to ledgers, sill plates, and structural connections. Refer to the IAPMO ER-493 load tables to size the anchor for your specific application.

Is the 304 stainless Titen HD good for outdoor use?

Yes. 304 stainless steel offers strong corrosion resistance for exterior and high-moisture applications. For coastal, marine, or salt-exposed environments, step up to 316 stainless, which adds molybdenum for greater resistance to chloride pitting. For inland exterior work, 304 is a durable, cost-effective choice.
