The 1/2-13 Drop-In Anchors are versatile anchors designed for various applications, including pipe hanging, overhead anchoring, and sprinkler systems. They are manufactured with an internally threaded, all-steel exterior shell that features an expansion cone insert used to anchor into concrete. These anchors are intended for use in concrete materials only and can be used with any head style screw. They are commonly used for overhead applications, including hanging pipe, duct work, machinery, and more. The anchors are available in different materials, including stainless steel for improved corrosion resistance. Proper installation requires a setting tool, which is sold separately.
