Frequently Asked Questions
What types of projects are Simpson concrete anchors suitable for?
What types of projects are Simpson concrete anchors suitable for?
Simpson anchors are designed for both structural and non-structural applications, including temporary attachments, permanent structural connections, wood-to-concrete fastenings, and masonry restoration. They provide reliable holding power across various substrates.
How do concrete screws differ from other anchors?
How do concrete screws differ from other anchors?
Concrete screws are self-tapping fasteners that attach directly to concrete and masonry without the need for chemical adhesives or expansion. They are perfect for applications where removable fastening is required, like attaching wood or fixtures to concrete.
How do I install adhesive anchors correctly?
How do I install adhesive anchors correctly?
Drill a clean hole to the specified diameter, remove dust, inject the adhesive, and insert the rod or rebar. Allow the chemical to cure for the recommended time before applying load. Following the manufacturer’s instructions ensures optimal performance.
What are Simpson Strong-Tie drop-in anchors, and where are they used?
What are Simpson Strong-Tie drop-in anchors, and where are they used?
Drop-in anchors are internally threaded expansion anchors installed flush with the concrete surface. They accept machine screws, making them ideal for overhead installations and clean, professional surface-mount connections.
What is the difference between sleeve anchors and wedge anchors?
What is the difference between sleeve anchors and wedge anchors?
Sleeve anchors are versatile, through-fastening anchors suitable for multiple base materials and removable connections. Wedge anchors are heavy-duty expansion anchors designed for permanent, high-load connections in solid concrete.
How do I choose the right anchor for my project?
How do I choose the right anchor for my project?
Selection depends on the base material, load requirements, and whether the connection is permanent or removable. For solid concrete, wedge anchors or adhesive anchors work well for structural connections, while concrete screws or sleeve anchors are better for removable or light-duty installations.
