Drive Links Drive Links: The drive links are the actual number of links on the chainsaw chain. You can actually count the links to get the exact number of links on your chain! Gauge Gage: The gauge of a chain refers to the thickness of its drive links. The drive link is on the underside of the chain. It's job is to secure the chain into the bar. Without it, your chain could fly off the saw. Pitch Pitch: The pitch of a chain refers to the distance between its drive links. The pitch can be measured by taking the distance between any three of the teeth and dividing that number by two.
