I did not use the supplied bolts . I used studs - stainless steel threaded rod cut to custom lengths and +blue Loctite.. Then use deep s/s nuts with washer and green Loctite.No stripped threads or bottomed-out bolts.
If you are tempted to use the competitive alternative kit linked below, be aware there is still much tedious fitting & trimming to do. Plus the Instructions have you locate the horizontal baffle at the bottom of the pan ! - where it is relatively ineffective . The kit comes with the marginally more effective 997 Swirl Pots(de-foamers).
