Concrete & Masonry Screw Anchors

Concrete screws, also commonly known as masonry screws, have great performance in concrete, block and brick applications.  Concrete screws are the ideal fastener for attaching wood to concrete.  Blue corrosion resistant coating enables them to withstand the harshest conditions.  These screws are known to be resistant to chipping, weather, and other abrasions.

The Titen HD® anchor is a patented, high-strength screw anchor for concrete and masonry. It is designed for optimum performance in both cracked and uncracked concrete; a requirement that the 2009 IBC places on post-installed anchors. The high strength, easy to install Titen HD anchor has been tested and shown to provide outstanding performance in cracked and uncracked concrete under both static and seismic loading conditions. The self-undercutting, non-expansion characteristics of the Titen HD anchor make it ideal for structural applications, even at reduced edge distances and spacings.

Recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications.

Wedge Anchors

Wedge anchors provide strong and secure fastening for heavy-duty applications in solid concrete. Ideal for anchoring structural supports, machinery, equipment, and shelving. Easy to install with high holding power and resistance to vibration and pull-out. Suitable for commercial and industrial use.

Simpson Strong-Tie Strong-Bolt® 2

The Strong-Bolt® 2 wedge anchor is the next-generation solution for cracked and uncracked concrete. Following rigorous testing according to ICC-ES acceptance criteria, the Strong-Bolt 2 anchor received classification as a Category 1 anchor, the highest attainable anchor category for performance in cracked concrete under static and seismic loading. Available in stainless steel, it is code-listed by ICC-ES under the 2009 IBC requirements for post-installed anchors in cracked and uncracked concrete.

Available in the popular 3/8" diameter, the Strong-Bolt 2 anchor is ideal for MEP applications in cracked concrete, such as hanging pipes, struts, equipment anchorage and other fixtures overhead. The anchor is also effective for lightweight- concrete applications, including concrete-over-metal decking.

The Strong-Bolt 2 wedge anchor in type 316 stainless steel also offers optimum performance in both cracked and uncracked concrete, meeting 2009 IBC standards for post-installed anchors. This wedge anchor is ideal for corrosive environments, including construction in coastal areas, wastewater and sewage treatment facilities, food processing facilities, pulp and paper mills, and other high-exposure environments

FEATURES

• Category 1 anchor classification: The Strong-Bolt 2 anchor received classification as a Category 1 anchor, which is established by performance in reliability tests in accordance with AC193 and ACI355.2 test criteria. Category 1 is the highest attainable anchor category for reliability.
• Tri-segmented clip: Each segment adjusts independently, increasing follow-up expansion should the hole increase in size as a result of a crack.
• Dual embossments on each clip segment: Enables clip to undercut into the concrete thereby increasing follow-up expansion should a crack occur.
• The 3/8" anchor solution approved for 3 ¼" concrete thickness: The Strong-Bolt 2 anchor can be installed in cracked concrete with a minimum thickness of 3 ¼", including concrete-over-metal decking.
• High-strength alloy clip on carbon-steel anchors: This special alloy clip offers improved performance.
• Standard (ANSI) fractional anchor: Fits most fixtures and installs with common drill bit sizes and tools.
• Type 316 stainless-steel clip on stainless steel anchors: In addition to superior corrosion resistance, a stainless-steel clip offers "memory" that contributes to the anchor's performance if the hole increases in size because of a crack.

MATERIAL

Carbon-steel stud with special alloy clip; stainless-steel stud with stainlesssteel clip.

Zinc-plated (carbon-steel)

Drop-In Anchors

Drop-in anchors are internally threaded, deformation-controlled expansion anchors with a preassembled expander plug, suitable for flush mount applications in solid base materials. The anchor is set by driving the expansion plug towards the bottom of the anchor using the setting tool. Drop-in anchors are also available in coilthreaded versions for 1/2" and 3/4" coil threaded rod.

The Lipped Drop-In (DIAL) features a lip at the top of the anchor body that keeps the top of the anchor flush with the concrete. This eliminates the need for precisely drilled hole depths and allows for easier flush installation, consistent embedment and uniform rod lengths.

Short Drop-In anchors are for use in solid and hollow concrete. The short length permits shallow embedment that helps to avoid drilling into rebar or prestressing strands. The wide surface flange enables the Short Drop-In to be installed in deep or bottomless holes. Fixed-depth drill bits are also available to take the guesswork out of drilling to the correct depth for these 3/8" and 1/2" Short Drop-Ins. Using the fixeddepth bit drill bit prevents overdrilling, which saves time and prolongs bit life.

Sleeve Anchors

Sleeve anchors are versatile expansion anchors designed for use in concrete, brick, and block. Ideal for securing handrails, window frames, shelving, and fixtures. Easy to install with reliable holding strength for medium to heavy-duty applications in both commercial and residential settings.

SDS Carbide Drill Bits

SDS Plus shank carbide drill bits provide fast and efficient drilling in concrete, masonry, brick, and stone. Designed with a durable carbide tip for extended life and superior performance. The SDS Plus shank offers secure grip and optimal energy transfer in rotary hammer drills. Ideal for construction, renovation, and heavy-duty applications.

Simpson Strong-Tie CSD/DSD Split-Drive Anchors

Simpson Strong-Tie CSD/DSD Split-Drive Anchors are one-piece expansion anchors for concrete, grout-filled block, and stone. Easy to install—just drill and drive. Available with countersunk heads (CSD) for a flush finish or duplex heads (DSD) for easy removal. Made from durable carbon steel with a zinc finish. Ideal for permanent or temporary fastening in masonry projects.

Drop-In Anchor Setting Tools

Drop-In Anchor Setting Tools make installation fast and easy by ensuring proper anchor depth and secure fit. Ideal for concrete anchoring applications in construction and industrial projects.

Four Crimp anchor head styles are available to handle different applications that include fastening wood or light-gauge steel, attaching concrete formwork, hanging overhead support for sprinkler pipes or suspended ceiling panels.

Warning: Industry studies show that hardened fasteners can experience performance problems in wet or corrosive environments. Accordingly, with the exception of the duplex anchor, use these products in dry, interior and non-corrosive environments only.

Simpson Strong-Tie offers adhesive formulations for anchoring into concrete and masonry and for repairing cracks in concrete.
