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 is a twisting force. The muscle you apply to the top of a screw-top jelly jar is torque. And when you use a wrench on a threaded fastener (such as a bolt, nut, screw, or stud), you're applying ...

As Charlie Chaplin figured out during his brief assembly-line career depicted in the 1936 film Modern Times, tightening bolts all day can be a real pain. Lucky for Charlie, and for any one of us ...

Measuring torque when installing threaded fasteners is the best indicator of future joint performance, right? Actually, bolt tension is a better performance indicator... Register or Sign in below to ...

At 7,500 rpm, the pistons in your race engine reach either top-dead-center or bottom-dead-center and change directions 25 times per second. That means the piston goes from traveling at top piston ...

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 ...

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 ...

Unless you’ve got a shop with a well-stocked hardware bin, it’s a trip to the hardware store when you need a special screw. But [Sanford Prime] has a different approach: he prints his hardware, at ...
