FAQ

What type of concrete is suitable for this sleeve anchor?

The SL37178H is designed for use in solid, cured concrete with a compressive strength of at least 3,000 psi. It performs well in both standard and high‑strength mixes, provided the hole is drilled to the recommended diameter and depth.

Can this anchor be used in masonry or brick?

While the anchor is optimized for concrete, it can be used in dense masonry when a proper expansion cavity is created. However, for optimal performance in brick or hollow block, a dedicated masonry anchor is recommended.

What wrench size is required for installation?

The hex‑head socket is sized for a 1/2‑inch wrench or socket, allowing easy torque application without the need for specialty tools.

Is the anchor reusable after removal?

Yes, the stainless‑steel sleeve can be re‑installed if the surrounding concrete remains undamaged. Inspect the anchor for any deformation before reuse to ensure continued load capacity.

How does the stainless‑steel finish compare to zinc‑coated options?

Stainless steel offers superior corrosion resistance, especially in saline or chemically aggressive environments, whereas zinc‑coated anchors provide basic protection but may degrade faster under the same conditions.
