    Thank you all for responding. I think I'll do a quick head shear off test - a few of the atom headed bolts and a few known standards.

      Bolls, actually fasteners are wide and varied.

      I did some tests on some a few years back right here. I said something about grade 9 fasteners and some thought they were just fluff for the folks that wanted them. Its not fluff.

      Inexpensive grade 8 bolts are considered to be the end of the road to some folks. Not so much.

      When I assembled my car I used mostly, throughout all very nice fasteners. Had to go to the aerospace industry (local) for many but that is not always the case.

      The car is assembled with either ARP (local also) or grade 9 fasteners.

      ARP and aerospace fasteners can get expensive, mainly when dealing with suspension. I sourced out some great manufactures and if you find my old post you will see some..

      Point being. Dont forget our tractor manufactures, they actually have some of the best at a decent price point. CAT (local) being one that I used a lot. JR

          JR, you may find this interesting.
          As luck would have it one of the TY channels I watch frequently just did a test sequence on a number of high performance OEM LS Chevy head bolts and studs and how they compare to various after market and hardware store grade 8 bolts.
          Interesting.

          Another test they did a couple of months ago that many may find enlightening.

              FKE is Fwu Kwang from Taiwan. They made/make cold heading machines. A company I worked at previously bought tons of FKE metric hardware made to our plating spec and it's always been top notch
              that 14.99 is a proprietary grade higher than 12.9 and is pretty skookum.

                I think my shop shelves are better than my 401k or IRA. I may be a millionaire!

                And if you look REAL close at an analog signal,
                You will find that it has discrete steps.

                  Actually the one from MSC is an 8" length while McMaster only seems to go up to 6" while the price is almost the same. So, size for size, MSC may be less expensive. But you gotta buy a pack of 5.

                    If you want to see some pricey bolts look at these. Which was discussed on the forum some time ago.

                        That bolt sure reminds me of the amateur sketch of the Crichton Leprechaun.

                          Thank you Sir. Guess you know me huh? Of course..

                          I watched all of the second vid. Yup.. That show reminded me why I like the Metric system so much more.

                          I did like the destructive testng.. Where I was working we had to do Non-Destructive testing... Very difficult, JR
