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 of internal threads or the bolt’s ...

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 ...

When hot rodders build a street machine or street rod, countless hours are expended selecting the proper major components, building the drivetrain, detailing the chassis, choosing the right tires and ...

Ever been strolling through a hardware store or perhaps an auto parts establishment and wondered of the meaning behind the markings on the hundreds of thousands of bolt heads on the shelf? Whether you ...

Measuring torque when installing threaded fasteners is the best indicator of future joint performance, right? Actually, bolt tension is a better performance indicator, but measuring torque is far ...

Over-tightened bolts done in the wrong sequence are the number one cause of warped parts, breakage, and consequently equipment failure. As cars became more sophisticated and exactness more crucial the ...

A certain amount of leeway is built into almost every factory part. Take Project Rust Bucket's turbocharger for example, which is now producing 37 pounds of boost instead of less than 20. Or the ...
