Screws
Concrete Screws
A concrete screw has a hardened, corrosion-resistant thread that cuts its own mating thread into pre-drilled concrete, block or brick. It holds by thread engagement in the base material rather than by an expanding anchor.
It anchors fixtures, conduits, brackets and sill plates into concrete, masonry and brick. Electrical and mechanical contractors use it for removable, high-hold fastening in solid bases.
