Hilti 1/4 x 2-1/4 Hex Head Titen Turbo (75/Box)

The 1/4 x 2-1/4 Titen Turbo solves the concrete fastening headache that every contractor knows — screws that bind, strip, or snap when you’re halfway through the day. The torque reduction channel actually works, and at 4.1 stars across multiple retailers, contractors are buying into the technology.

This isn’t a Hilti product, though. Simpson Strong-Tie manufactures the Titen Turbo, despite the common confusion. The distinction matters when you’re ordering replacements or looking up specs.

How Torque Reduction Technology Changes Installation

The Torque-reduction channel (Turbo technology) traps dust to prevent binding/stripping. Traditional concrete screws push dust up the threads during installation. That dust packs tight, increases driving resistance, and eventually strips the head or snaps the screw. The Titen Turbo’s channel gives that dust somewhere to go.

The innovative Torque Reduction Channel minimizes dust obstruction, reducing binding, stripping, and snapping during installation, while maintaining strong holding power. The serrated leading thread cuts cleaner than standard threads, and the pointed tip starts precisely — no wandering on smooth concrete surfaces.

Installation specs matter with concrete fasteners:

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
Coating	Blue Zinc with Ceramic Finish (Climaseal Blue equivalent)

Some users recommend using a fresh 3/16 bit to ensure proper fit. Worn bits create oversized holes that reduce holding strength. The blue coating handles dry interior environments — Montana basements, mechanical rooms, interior framing.

Where These Screws Excel

Applications include: 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 2-1/4” length with 1” minimum embedment leaves 1-1/4” for fixture thickness. That’s perfect for mounting electrical boxes through 1/2” drywall into concrete, or securing 2x4 furring strips for basement finishing. The hex head design means standard nut drivers work — no hunting for special bits.

Compared to standard Tapcon screws, Titen Turbo includes a dust-clearing channel which makes it easier to drive manually or with less powerful tools. 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.

Code Compliance and Testing

The screws carry ICC-ES ESR-712 (Code compliant for concrete), ICC-ES ESR-716 (Code compliant for masonry), International Building Code (IBC) & International Residential Code (IRC) compliance, Florida Product Approval (FL-16230), Miami-Dade County NOA (25-1002.03), and City of Los Angeles (COLA) Research Report.

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

Installation Process

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.

The drill depth needs to be at least 1/2” deeper than embedment depth. That extra space gives drilling dust room to settle without interfering with full embedment. Clean holes matter — compressed air or a nylon brush removes the dust that causes binding.

Compatible materials include: Normal-weight concrete, Lightweight concrete, Hollow CMU (Block), Grout-filled CMU, Solid brick. Works with hammer drills, impact drivers, or standard drills with the 5/16” nut driver.

Bottom Line

The box includes 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.

Users praise the reduced effort required to drive the screws and the fact that they are less prone to snapping than competitors. For contractors tired of snapped Tapcons and stripped heads, the torque reduction technology delivers measurable benefits. The trade-off is knowing these are Simpson Strong-Tie products, not Hilti — order accordingly.

FAQ

What size masonry bit do I need for the 1/4” Titen Turbo?

Use a 3/16 inch ANSI Masonry Bit. Fresh bits create proper-sized holes for maximum holding strength.

How deep should I embed these screws in concrete?

Minimum embedment is 1 inch. Drill holes at least 1/2” deeper than embedment to accommodate dust.

Can I use these outdoors or in wet locations?

The Blue Zinc with Ceramic Finish (Climaseal Blue equivalent) provides corrosion resistance for dry/interior environments. Not recommended for exterior or wet locations.

What’s the maximum material thickness I can fasten?

Maximum fixture thickness is 1-1/4 inches with the 2-1/4” length screw.

Do these work in hollow concrete block?

Yes, compatible materials include Hollow CMU (Block) as well as grout-filled CMU and solid brick.
