After twisting the wire, how many twists should be measured beyond the second bolt and trimmed?

When securing a wire around fasteners such as bolts, it's important to ensure adequate twists are made for proper tension and stability. The correct practice is to measure 3 to 5 twists beyond the second bolt after the wire has been twisted. This range allows for a secure hold that assures the wire maintains its integrity and function, providing enough tension without being excessive, which could lead to damage or failure.

Having 3 to 5 twists ensures that there is a sufficient amount of wire to effectively grip the structure, preventing slippage. It also allows for any slight shifts or movements in assembly that may occur over time. Adequate twisting serves not only the immediate purpose of fastening but also enhances long-term reliability in the assembly process.

The other ranges provided may not offer the optimal balance of tension and security needed for effective assembly in aerospace applications, where precision and reliability are paramount.
