Good for high-strength fastening, these screws are made from alloy steel comparable in strength to Grade 9 steel. The head makes 12 points of contact with a wrench to handle more torque than a socket head or hex head screw.
About half the strength of medium-strength bolts, these Grade 2 bolts are for light duty fastening. Carriage bolts have a smooth, rounded head for a finished look. The square neck keeps these bolts from turning when tightening a nut.

About half the strength of medium-strength screws, these screws are for light duty fastening applications, such as securing access panels. Large flat sides make these screws easy to grip with a wrench and keep them from rotating in square holes.
You can use these versatile hangers in a threaded hole (as you would a screw), or secure them with a nut (as you would a bolt).
Drive these into wood with an adjustable wrench, pliers, or a special driver tool.
