In this episode we head out with Lake Speed Jr to Jasper Engines & Transmissions in Jasper, Indiana to see Jasper’s Noah and AERA’s Chuck Lynch for a master class on getting the right bolt clamp force in your engine.

The guys break down in plain language the difference between clamp load and torque, the stress vs strain curve, and the dos and don’ts of getting the right pre-load and yield points on your bolts.

Along the with the instruction, the boys also walk through some up-close demos demonstrating torque and stretch, and deliver some great info on how factors like bolt threading, washers, lubricants, etc., all affect clamp load and bolt reliability.
