Tightening anchor bolts involves bringing the nuts into firm contact with the base plate using a specific method to achieve a "snug tight" condition.
According to the provided reference, the process for tightening anchor bolts primarily focuses on achieving a "snug tight" state. This state is clearly defined, and a particular method for applying the necessary force is outlined.
Achieving Snug Tight Condition
The initial step in tightening anchor bolts is to bring the leveling nuts and top nuts into contact with the base plate until they reach a "snug tight" condition.
What is "Snug Tight"?
Based on the reference, "Snug tight is defined as the tighten top nuts so they fully contact the base plate." This means the nuts are tightened just enough to ensure there is full contact between the nuts and the base plate, without necessarily applying a significant preload.
Applying Force for Tightening
The reference specifies how to apply the force required to achieve this snug tight condition:
- Method: Apply the full effort of one person.
- Tool: Use a wrench.
- Wrench Length: The wrench should have a length equal to 14 times the bolt diameter.
- Minimum Wrench Length: The wrench length should not be less than 18 inches, regardless of the bolt diameter.
- Action: Pull firmly by leaning back.
By following these steps and applying force as described, the anchor bolts are tightened to the defined snug tight state, ensuring the top nuts are in full contact with the base plate.
