KD Fasteners, Inc.® supplies a wide range of concrete screws and concrete anchors for construction, industrial, and commercial fastening applications. As an authorized distributor of Simpson Strong-Tie® concrete fastening systems since 1987, we stock and supply everything from self-tapping concrete screws to heavy-duty wedge and expansion anchors — with the ability to drop-ship directly from the manufacturer or run a dedicated stocking program to keep your parts on hand. Whether you're fastening into solid concrete, block, or masonry, we can help you find the right screw or anchor for the job, in standard sizes or by custom part specification.
Concrete Screws vs. Concrete Anchors: What's the Difference
"Concrete screw" and "concrete anchor" are often used interchangeably, but they describe two different fastening methods.
A concrete screw is a self-tapping fastener that threads directly into a pre-drilled hole in concrete or masonry — no separate hardware required. Its hardened threads cut into the material as it's driven, creating a secure hold in a single step. This makes concrete screws a fast, straightforward option for lighter- to medium-duty fastening.
A concrete anchor, on the other hand, is typically a two-part system. A sleeve, shield, or wedge is set into a pre-drilled hole first, then expands or locks into place as a separate screw or bolt is driven or tightened into it. Anchors generally offer higher load capacity and are the preferred choice for heavier structural connections or installations into hollow or less solid substrates.
Concrete Screw Types We Supply
KD Fasteners supplies concrete screws in a range of styles, finishes, and drive types, including:
- Titen® concrete and masonry screws — available in steel and stainless steel
- Titen HD® — a heavy-duty, self-tapping screw-anchor for high-load structural connections, also available as a Rod Hanger, Rod Coupler, and Mini version
- Tapking concrete screws — Ruspert-finished, available with slotted hex washer or Phillips flat head drive
- Blue-finish concrete screws — available with slotted or un-slotted hex washer head, and flat head styles
Concrete Anchors We Supply
For applications that call for a two-part anchoring system, we supply:
- Strong-Bolt® and Wedge-All® wedge anchors
- Torq-Cut® anchors
- Easy-set pin-drive expansion anchors
- Expansion screw anchors
- Hollow wall anchors
- Lag screw expansion shields
- Split drive anchors
- Nail-on pin-drive anchors
- Plastic screw anchors
- Machine screw anchors
Installing Concrete Screws & Anchors
Concrete screws generally require a pre-drilled pilot hole sized to match the screw's diameter — driving directly into solid concrete without pre-drilling isn't recommended and can damage the fastener or the surrounding material. Anchors also require a properly sized and drilled hole to allow the sleeve, shield, or wedge to seat and expand correctly. Hole diameter, depth, and embedment all affect holding strength, so matching the fastener to your specific substrate and load requirement is important. For exact sizing, spacing, and load capacity for your application, contact our team or request a quote — we're happy to help you select the right screw or anchor for the job.
Concrete Screw Applications & Industries
Concrete screws and anchors are used across industrial manufacturing, general contracting, and facilities where fasteners need to secure into concrete, block, or masonry. They're also common in marine construction and dock/pier installations, as well as oil and gas facility fastening, where equipment mounting and structural attachment into concrete surfaces is routine. Common uses include mounting framing and hardware, securing equipment and machinery, hanging conduit and rod systems, and general structural attachment.

Concrete Screws & Anchors FAQ
Can I screw directly into concrete?
Most concrete screws require a pre-drilled pilot hole before installation. Driving a screw directly into solid concrete without pre-drilling can damage the fastener and won't provide a secure hold.
Do I need to pre-drill for concrete screws?
Yes. Concrete screws are designed to thread into a pre-drilled hole sized to match the screw's diameter, which allows the threads to properly grip the surrounding material.
What screws are best for concrete?
Self-tapping concrete screws, like Titen® or Tapking-style screws, are designed specifically for fastening into concrete and masonry. For heavier loads, a two-part concrete anchor, such as a wedge or expansion anchor, may be a better fit.
How much weight can a concrete screw hold?
Load capacity depends on the screw's diameter, embedment depth, and the condition of the concrete or masonry it's installed in. Contact our team or request a quote for load specifications on a particular screw or anchor.
