Zinc Hex Nut Sleeve Anchor

Q. What are sleeve anchors used for in hurricane shutter systems?

Sleeve anchors are used to mount shutter brackets or tracks to concrete, block, or brick structures. As the anchor is tightened, the sleeve expands inside the drilled hole, locking it securely in place.

Q. How do I install a sleeve anchor?

Drill a hole the same diameter as the anchor into the masonry. Clean the hole, insert the anchor through the shutter hardware, then tighten the bolt to expand and lock the sleeve.

Q. What size sleeve anchor should I use?

¼″ and ⅜″ diameter sleeve anchors are both commonly used for hurricane shutter hardware. ¼″ diameter works well for standard panels, while ⅜″ offers extra holding strength for larger or reinforced installations. Be sure to select a length that allows at least 1½″ of embedment into the concrete while accommodating your hardware thickness.

Q. What’s the difference between zinc-plated and stainless steel sleeve anchors?

Zinc-plated anchors are more affordable and suitable for interior or low-exposure areas. Stainless steel is preferred in coastal or humid climates for its superior corrosion resistance.

Q. Are sleeve anchors better than wedge anchors for shutters?

Sleeve anchors provide excellent holding strength and are easier to install in softer masonry, like block. Wedge anchors may offer higher load ratings in solid concrete, but either can be effective depending on the substrate and engineering specs.
