FACTS ABOUT FASTENERS

摘要

Using fasteners properly seems straightforward - tighten them to spec and all is well. However, in reality, there are many nuances in the selection and application of fasteners that can make the difference between a well-built engine and a candidate for self-destruction. The first thing to understand is that fasteners act much the same as a spring due to the physics of stretch and rebound. A stud or bolt must be stretched to produce clamping force. For example, a typical 3/8" connecting rod bolt will need to be stretched some .006" to provide 10,000 lbs. of force.
