I tested a chinesium bolt against bolts that were 10 times more expensive.This is a homebrew DEMONSTRATION of one bolt yield to failure. The JH grade 8 bolts were stronger than the US made LE grade 8, the grade 9 alloy bolts and the L9!

I screw, I nut, I bolt, then I washer. 😉
Love your work, you are my favourite. That bolt you were holding near the start in front of your scope, with the strange looking head. Is that the same as what a Bridgeport mill table lock has, with the spring loaded button to reposition the handle? If so what is that head type called?
Funny I'm seeing this. I'm in right this second writing this on a shipping label and I'm going to place them in the screw section in home depot.
Screws made in China or purposely built to be weak in strip to cause micro stress to people in country that has a democracy. This is just one of the many soft wars that do.
You're are a cool dude
I don't know what was the most impressive thing the sayings or the science
Can never trust lack of quality control lying cheating cut every corner scum bag Communist china products. Had way too many defects with POS garbage china products. They are best in class at manufacturing extremely toxic sheet rock, boot leg circuit breakers, children's toys with poisonous lead paint, dog & cat food that kills them etc.
Had navy guys get screwed, blued & tattooed.
Looks like Ave built a home made rowing machine!

I thought you were gonna streeeeech them out with the old hydriaulic pumper there.
worked on a boat that came from china once. m16 and m20 bolts and we would just tighten them until they snapped be cause that was faster and easyer then to losen them when they had been painted. the quality markings on them where all over the place, some where marked as very low grade and some was marked high grade, but they all where shit.
I'm in the middle of stocking bolts at Home Depot right now
I knew decent bolts had some force in them but i had no idea we are talking about 100 thousand+ psi
Thats crazy !!!
Teflon coated nuts and bolts are the cats' ass.
Could not get pass the wedge analogy. A thread is an inclined ramp in a spiral. Torque measures the stretch in the fastener based on the angle of this ramp, and the force applied. Wedge implies the bolt tightens due to how far into the threads it goes, like pipe threads.
