Simpson 1/4" x 3-3/4" Titen Turbo Flat-Head Screw Anchor from Simpson delivers fast, reliable fastening in concrete and masonry applications. Engineered with a revolutionary thread design that reduces driving torque while maintaining superior holding power, this flat-head screw anchor is built for professionals who demand consistent, trouble-free installation in wood-to-concrete and structural anchoring projects. The white ceramic coating gives it a clean, finished appearance while providing added durability against corrosion - making it a practical choice wherever a low-profile, flush-mounted anchor is needed.

Key Features

• Torque Reduction Channel between threads - channels drilling dust away during installation, significantly reducing binding, stripping, and snapping so anchors drive cleanly every time
• Patented thread design with lower driving torque - lets installers drive anchors faster with less effort while still achieving superior holding power in concrete and masonry
• 1/4" diameter x 3-3/4" length - provides deep embedment for strong, secure fastening in wood-to-concrete and structural anchoring applications
• T30 6-Lobe drive type - delivers excellent torque transfer and reduces cam-out, keeping the drive bit engaged for faster, more controlled installation
• Flat-head profile - sits flush with the surface after installation, producing a clean, finished look ideal for visible or finished surfaces
• Zinc plated with ceramic coating in white - resists corrosion while the white finish blends into painted or white-finished surfaces for a professional, unobtrusive appearance
• Carbon steel construction - provides the tensile strength and durability needed for demanding concrete and masonry anchoring applications
• Requires 3/16" drill bit - a tight, precise fit to the pilot hole size ensures maximum holding power and a secure anchor in the base material

Why This Product

• The Torque Reduction Channel addresses one of the most common frustrations in screw anchor installation - torque buildup that leads to binding, stripped heads, or snapped anchors - delivering consistently smooth drives even in hard concrete and masonry
• The flat-head design sits flush after installation, making this anchor the right choice for finished surfaces, trim work, and applications where a protruding head is not acceptable
• The white ceramic coating over zinc plating means the anchor visually disappears against white or light-colored surfaces, eliminating the need to paint or conceal fastener heads after installation
• The T30 6-Lobe drive reduces cam-out and slippage during high-torque driving, helping protect both the fastener head and the surrounding material surface from damage

Frequently Asked Questions

What size drill bit do I need for this screw anchor?

This Titen Turbo flat-head screw anchor requires a 3/16" drill bit for the pilot hole. Using the correct bit size is essential for achieving the rated holding power and ensuring a secure, tight anchor in concrete or masonry.

What is the Torque Reduction Channel and why does it matter?

The Torque Reduction Channel is a design feature built between the threads of the Titen Turbo anchor. It gives drilling dust a place to go as the anchor is driven, which significantly reduces torque buildup - the main cause of binding, stripping, and snapping during installation. The result is a smoother, more reliable drive every time.

Why does this anchor have a white coating instead of a standard silver zinc finish?

This screw anchor features a zinc plating with an additional ceramic coating in white. The white finish allows the anchor head to blend into white or light-colored surfaces after installation, making it ideal for finish carpentry, trim, and any application where a visible silver fastener head would be undesirable.

What drive bit does the T30 6-Lobe drive type require?

The T30 6-Lobe drive requires a T30 Torx-style bit for installation. The 6-lobe design improves torque transfer and reduces cam-out compared to standard Phillips or square drives, helping protect both the fastener head and surrounding materials during high-torque driving into concrete or masonry.
