Features
-
Lag screws are generally larger than normal wood screws and they typically have a hexagonal drive head.
Types
-
Lag screws are available in lengths up to 18 inches and with diameters from 1/4 to 1/2 inch.

Use
-
Typically you should drive a lag screw with a wrench, and, if you're drilling into masonry or concrete, you should anchor it with a lag shield. When using long lag screws, drill a thinner pilot hole first.
Benefits

Lag screws can reliably support significant amounts of weight when properly employed.
Warnings
-
Always select the largest lag screw you are able to use; it is the most important factor to ensure that your project is a success.
