Final answer:
When installing a nut on a clevis bolt, it is important to refer to the manufacturer's specifications for the correct torque value. Using a torque wrench and the appropriate size and type of wrench or socket can help ensure proper tightening without causing damage.
Step-by-step explanation:
When installing a nut on a clevis bolt to attach a cable fitting to a control surface horn, the nut should be tightened to a specific torque value. This torque value is determined by the manufacturer and can vary depending on the specific application. To ensure the correct tightness, it is important to refer to the manufacturer's specifications or guidelines.
Using a torque wrench is the most accurate way to apply the correct torque. It allows you to measure the amount of force applied while tightening the nut. This helps to prevent over-tightening, which can cause damage to the bolt or the control surface, as well as under-tightening, which may lead to the nut coming loose.
It is also important to use the correct size and type of wrench or socket to ensure a proper fit on the nut. This will help prevent slipping or rounding off the corners of the nut, which can cause difficulty in future adjustments or removal.
