Simpson Strong-Tie Titen Turbo 1/4 x 2-1/4 Hex Head Concrete Screws

The Simpson Strong-Tie Titen Turbo isn’t just another concrete screw — it’s the one that won’t strip out halfway through installation. The torque-reduction channel traps dust away from the threads, solving the most common concrete screw failure point. At 4.1 stars on Home Depot, contractors report reduced effort and less prone to snapping than competitors.

This 75-count box of 1/4-inch diameter, 2-1/4-inch long screws targets professional contractors mounting electrical boxes, conduit, furring strips, and light-duty fixtures to concrete and masonry. The blue zinc coating with ceramic finish provides corrosion resistance for dry interior environments — perfect for Montana basements and commercial buildings.

The Dust Channel That Changes Everything

The torque-reduction channel (Turbo technology) traps dust to prevent binding and stripping during installation. Anyone who’s snapped a Tapcon knows exactly why this matters. Traditional concrete screws force you to clear the hole perfectly or risk binding as dust packs between the threads and concrete. The Titen Turbo’s channel gives that dust somewhere to go.

The serrated leading thread cuts into masonry and concrete more aggressively than standard screws, while the pointed tip enables precise starts and easy wood-to-concrete installation. Combined with the high-low thread design for maximum pull-out strength, you get a screw that drives easier but holds harder.

Compared to standard Tapcon screws, the dust-clearing channel makes it easier to drive manually or with less powerful tools. That’s the difference between finishing a job and breaking bits.

Installation Specifications

Specification	Value
Drill Bit Size	3/16 inch ANSI Masonry Bit
Minimum Embedment	1 inch
Maximum Fixture Thickness	1-1/4 inches
Drive Tool	5/16” Hex Nut Driver
Hole Depth	Minimum of 1/2” deeper than the anchor’s embedment depth

The installation sequence stays simple: 1. Drill the hole. 2. Clean out dust with a brush or air. 3. Drive the screw through the fixture until seated. Avoid over-tightening.

Some users recommend using a fresh 3/16 bit to ensure proper fit. Worn bits create oversized holes that compromise holding power.

Where It Works and Where It’s Legal

These screws carry ICC-ES ESR-712 (Code compliant for concrete) and ESR-716 (Code compliant for masonry) certifications, plus International Building Code (IBC) & International Residential Code (IRC) compliance. Florida Product Approval (FL-16230) and Miami-Dade County NOA (25-1002.03) round out the approvals for demanding environments.

Compatible materials include normal-weight concrete, lightweight concrete, hollow CMU (Block), grout-filled CMU, and solid brick. That covers most Montana commercial construction — from concrete tilt-ups to CMU block buildings.

Application-wise, these excel at:

• Electrical: Mounting conduit, switch boxes, and electrical boxes
• General: Installing window frames and door thresholds
• Light Duty: Mounting handrails, signage, and basement furring strips
• Storage: Attaching shelf brackets to block or concrete walls

The Brand Confusion

Simpson Strong-Tie (Note: Often confused with Hilti, but Titen Turbo is a Simpson brand). Simpson makes the Titen Turbo — not Hilti. Hilti KH-EZ is a higher-load heavy-duty anchor; Titen Turbo is optimized for speed and reduced torque in light-to-medium masonry applications.

Simpson Strong-Tie Limited Warranty (1 year): Guaranteed to be free from defects in material or workmanship. Proper installation per manufacturer guidelines is required for performance warranty.

FAQ

What size drill bit do I need for the 1/4” Titen Turbo? 3/16 inch ANSI Masonry Bit is required. Some users recommend using a fresh 3/16 bit to ensure proper fit.

How deep should I drill the hole? Minimum of 1/2” deeper than the anchor’s embedment depth. With 1 inch minimum embedment, drill at least 1-1/2 inches deep.

Can I use these in hollow block? Yes. Compatible materials include hollow CMU (Block) and grout-filled CMU.

What’s included in the box? 75 pieces of 1/4” x 2-1/4” Hex Head Titen Turbo Screw Anchors. Driver bits are typically NOT included in the hex-head box packs.

How do these compare to regular Tapcons? Titen Turbo includes a dust-clearing channel which makes it easier to drive manually or with less powerful tools compared to standard Tapcon screws.
