Size M4-M20 Galvanized Steel Wood Screws - Hexagon Lag Screws/Hex Head Lag Bolts DIN571

Lag bolts are heavy-duty bolts with threads that grip the medium when a hole has first been drilled. This is called self-tapping. The tapered point or gimlet point of the bolt helps pull the bolt into the hole and secure its threads.

Lag bolts sport a hex head which is where the label hex lag screw originates. The bolt came to be called lag bolt due to being used in joining barrel staves which were also called lags. Lag bolts secure joints because nails aren’t as strong as a lag bolt for joining joints.

There is no difference between lag bolts and lag screws. Both are called lag screws. Longer screws or bolts have space between the head and the threads that are called a shoulder.
