Calculating the bolt preload torque needed to hold parts together is often a time-consuming process using antiquated tools. Speed things up with a newer, user ...

Just about every vehicle is held together using a lot of small components, including bolts. What exactly is a torque-to-yield, also known as a TTY bolt?

Most engineers who deal with bolted joints are familiar with torque tables for SAE-grade bolts, but these are all too often used without regard for the yield strength ... Register or Sign in below to ...

What does it mean when the mechanic says he needs to “re-torque” the bolts, after I recently replaced the car’s front suspension? Most car components are secured to the chassis or sub-assemblies using ...

Torque-to-yield (TTY) bolts, also known as angle torque or stretch bolts, are fasteners designed to be tightened beyond their elastic range and into a controlled yield zone. Their job is to apply a ...
