Steel Square-Drive Flat Head Screws for Wood
Beveled under the head for use in countersunk holes, these steel screws press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Length is measured from the top of the head.
Black-oxide steel screws are mildly corrosion resistant in dry environments.

Steel Hex Head Screws for Wood
These steel screws have corrosion-resistant finishes. Also known as lag bolts, they have a hex head for a secure grip with a wrench. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Length is measured from under the head.
Black-oxide steel screws have a coating that protects the steel from rusting in dry environments and blends in with dark surfaces.

Flat Head Screws for Particleboard and Fiberboard
Black Oxide
Beveled under the head for use in countersunk holes. Sharp, angled threads cut into particleboard, medium-density fiberboard (MDF), and hardboard such as masonite without splitting. Length is measured from the top of the head.
Black-oxide steel screws are mildly corrosion resistant in dry environments.

Steel Wood Screw Threaded Studs
These studs are also known as hanger bolts—use them to hang, mount, and fasten parts to wood structures. Install with a stud driver or create wrench flats by threading two nuts onto the stud and jamming them together.
Black-oxide steel studs are mildly corrosion resistant in dry environments.
