To tighten fully threaded structural bolts, a torque wrench or other calibrated instrument should be used to apply the recommended amount of torque. A study by the Society of Automotive Engineers (SAE) found that over-tightening or under-tightening can result in reduced strength and durability, and even lead to bolt failure. Therefore, it is essential to follow the manufacturer’s recommendations for torque values and tightening procedures to ensure a secure connection. Additionally, the bolt’s threads should be lubricated with a suitable lubricant to reduce friction and prevent galling or seizure.
What are the common causes of failure in fully threaded structural bolts, and how can they be prevented?
The common causes of failure in fully threaded structural bolts include over-tightening, under-tightening, corrosion, and fatigue. According to a study by the National Institute of Standards and Technology (NIST), over-tightening can cause the bolt to fail due to excessive stress and strain, while under-tightening can result in a loose connection that is prone to vibration and fatigue. Corrosion can also cause bolt failure by weakening the material and reducing its strength and durability.
To prevent failure in fully threaded structural bolts, it is essential to follow proper installation and maintenance procedures, including tightening the bolt to the recommended torque value and lubricating the threads to reduce friction. A study by the American Society of Civil Engineers (ASCE) found that regular inspection and maintenance can help identify potential issues before they become major problems. Additionally, using high-quality bolts that meet industry standards and specifications can help reduce the risk of failure. By understanding the common causes of failure and taking steps to prevent them, construction teams can ensure a safe and secure connection that can withstand the demands of the project.
