How many bolts does a turnbuckle contain?

A turnbuckle typically contains two bolts. Specifically, it features two threads: one at each end which is often referred to as a "hook" or "eye" that allows for the connection of different parts, such as cables or rods. The overall design enables tension to be adjusted by rotating the central body, causing the two ends to move closer or further apart. This mechanism effectively increases or decreases tension within the connected components, making turnbuckles crucial in various applications where secure and adjustable connections are necessary, such as in rigging, construction, and machinery. The presence of two bolts is essential to its function, as having a single bolt would not provide the necessary adjustments and stability required for its intended use.
