What is the primary function of a tie strap in a chainsaw chain?

The primary function of a tie strap in a chainsaw chain is to hold the saw chain together. Tie straps are essential components that serve as links between the drive links of the chain. While they contribute to the overall structure, their main role is ensuring that the links remain connected, allowing the chain to move seamlessly around the guide bar during operation. This connection is crucial for the effective functioning of the chainsaw, as it facilitates smooth cutting action and maintains the chain's integrity under various stresses.

The other functions listed, such as connecting drive links, regulating oil flow, and stabilizing the bar, pertain to different components or features of the chainsaw or chain, but they are not the primary function of the tie strap itself.
