What is not included in the inspection for the snug tight method of installation?

The snug tight method of installation focuses primarily on achieving a certain level of tension in the bolts to ensure that structural connections are adequately secured. This method does not require a quantifiable measurement of the clamping force provided by the bolt, as the emphasis is on achieving a "snug" condition that is sufficient for most applications without necessitating detailed torque calculations.

In this method, ensuring the bolts are tight enough to generate the necessary friction between the connected parts is crucial, but it does not drill down into measuring the actual clamping force. Instead, the installation keeps the assembly sufficiently tight to avoid any slippage under the expected loads.

Other aspects such as the presence of lubricant, the condition of threads, and the visual appearance of the bolt head are relevant for inspection under the snug tight installation method. Each of these factors can influence the effectiveness and safety of the connection. For instance, the presence of lubricant may affect friction values, and the condition of threads is essential for ensuring proper engagement and strength. Visual assessment of the bolt head can help identify any damage or irregularities that could compromise the installation integrity.
