Use Cases

Match the anchor to the fastening job

Concrete screw anchors are represented for light- to medium-duty attachment work such as electrical boxes and light fixtures. Sleeve anchors provide an expanding fastening method in concrete, cement block, brick, and stone. Nail drive anchors are intended for light-duty and tamper-resistant fastening, while rod hangers create an anchoring point for supported overhead systems.

How to Choose

Compare base material, size, head style, and connection

Confirm the listed base-material compatibility first. Then compare anchor diameter and length, the needed head profile, and the installation method. Concrete screw anchors are available with Phillips flat heads or slotted hex washer heads; the rod hanger is made for compatible 1/4 in.-20 threaded rod.

Applications

Support installation and maintenance work

Use the listed concrete screw anchor options where attachment to concrete, brick, masonry block, or wood base materials is required. Select sleeve anchors for the listed masonry surfaces, including soft concrete. Choose bottom-mount rod hangers for threaded-rod suspension from concrete slabs, beams, or concrete over metal.

Additional Info

Consider installation accessories and pack quantity

Several concrete screw anchor options use a gimlet point that taps or forms threads during installation. An installation kit is available to support Phillips and hex head concrete screws across all lengths, with accessories that fit a standard 3-jaw style chuck. The represented anchor and hanger products are supplied in 100-piece packs.
