            Q. What are combo sidewalk bolts used for in hurricane shutter systems?

            They’re commonly used to fasten shutters (like panel or accordion styles) into concrete, block, or masonry using lead anchors. Sidewalk bolts’ flat heads sit flush for a clean, low-profile finish that resists tampering and wind uplift.

            Q. What makes the combo drive useful?

            The combination of slotted and Phillips drives gives installers more flexibility, so you can use whichever tool you have on hand, including standard screwdrivers or power drill bits.

            Q. Why choose 18-8 stainless steel?

            18-8 stainless offers good corrosion resistance for most outdoor applications. For marine or high-salinity environments, upgrade to 316 stainless for enhanced durability.
