A piezoelectric load-sensing washer currently under development provides a more accurate way to measure the clamping force exerted by the bolt it is on. A piezoelectric load-sensing washer being ...

The scatter of bolt clamping force tightened by the conventional torque control method very often causes loosening and fatigue failure of bolted joints. Different values of frictional coefficients ...

Workers often tighten bolts to 75% to 80% of the bolt proof load. This works for many joints, but in some cases, external tensile loads reduce bolt clamping forces to zero. Something other than the 75 ...

Dr. Boy GmbH & Co. KG is modifying its largest vertical injection molding machine to increase the clamping force by 50 kilonewtons to 600 kN by the end of this year. The Boy 60 EVV, an insert molding ...

When was the last time you overheard someone at the local track or gas station brag about a new set of bolts? You don't remember? It was probably never. Let's face facts: Bolts don't glimmer and shine ...

Jointing is a basic function of engineering. For example, bolting two parts together can involve material properties and loading forces. Here, we will focus on preloading, shear and tear-out in a ...
