Steel Female-Threaded Anchors for Concrete
A zinc plating provides corrosion resistance in wet environments. Also known as drop-in anchors, these are often used for overhead applications because the anchor's internal plug expands in four directions to hold the anchor firmly inside the hole before inserting a threaded rod or bolt. To install, place the anchor into the hole, insert the required installation tool (sold separately) into the anchor, and drive with a hammer until the thicker portion of the tool makes contact with the anchor. Pull-out strength and shear strength values are 25% of the ultimate values for normal-weight concrete.
Anchors can be installed below the base of the surface as well as flush with the surface. Use those with a coil thread to support temporary concrete formwork. Their threads are shallow and widely spaced for quick threading with a compatible rod or bolt.

Quick-Clamping Coil-Threaded Rods, Screws, and Nuts
Combine fast-threading components to build a clamping assembly. The coil-style threads are shallow and widely spaced for quick threading.
Flange nuts have a large bearing surface to cover holes and resist vibration.
Wing nuts can be fastened by hand.
