By applying the three-dimensional FEM, the relationship between the tightening force F and the tightening torque T was clarified by varying the pitch difference alpha during the whole nut tightening/untightening process. The well-known F-T formula available for tightening the normal nut (alpha = ...
A torque wrench and bolt gauge combination, helps nut and bolt failures and flange leaks. Engineers want tension not torque.
Comparison of cannulated screw with tension band wiring versus compressive cannulated locking bolt and nut device (CompresSURE) in patella fractures-a cada... OBJECTIVE: The purpose of this study was to determine if proximity of cannulated lag screws to the articular surface of the patella combined...

I have Grade 12.9 Nuts and Bolts on a flange, they are torqued up to 1000nM (within last 6 months) The Flange needs to be disconnected and reconnected, is it possible to reuse the Nuts? Thanks in advance Reply Dane McKinnonsays: ...
accuracy achieved by using only a torque-based solution, so it makes little sense to invest in tension-measuring fasteners,” said Brooks. “Whereas Maxbolt® and SPC4® deliver much greater precision, at +/-5%, enabling the user to realize the benefit of the tension versus torque ...
The cheaper torque-tension rebar system, which is typically fully-grouted with 2-speed resin and which typically provides low bolt tension, is not used in CONSOL's Pittsburgh seam mines. Rather, it is used in CONSOL's Central Appalachia mines, where the roof rocks have CMRR rating of 50 ...

Step 2: The prestressed anchor bolt tension simulation. Step 3: Apply vertical force V. Step 4: Apply horizontal force H. Step 5: Apply horizontal torque T. Step 6: Apply bending moment M and the calculation is terminated when the specified load is applied. 4. Response of the Foundation ...
slippage occurred. The root cause is that the frictional resistance provided by the pre-tension is insufficient to counteract the applied load. At this point, most of the load was borne by the bolts on both sides of the mid-span. Because of the smaller moment of inertia of these bolts, ...
