Unquestionably the most important fasteners in any engine are the connecting rod bolts, as they hold the key to the entire rotating assembly.
A broken bolt will lead to a catastrophic engine failure. As you can imagine, the most critical joint is where the connecting rods mate. The rod bolts must support the primary tension loads caused by each rotation (or cycle) of the crankshaft. When the crank rotates, the big end of the connecting rod essentially becomes oval shaped and the rod bolts bend. as the crankshaft continues to rotate, the rod becomes round again. With alternating tension loads and cyclic bending of the bolts, it's very important to install fasteners that are able exert a clamping force greater than the load imposed on the joint (tension). In an addition to utilizing a rod bolt with sufficient strength to withstand the tremendous cyclic strains placed upon it, it is absolutely imperative that the bolts be properly tightened. The preferred method of monitoring the correct amount of tension is through a stretch guage. this is far more accurate than a tension wrench moreover through subsequently checking the rod bolts length at teardowns, it is possible to determine if it has been stressed beyond safe limits and must be replaced.
