I am looking to order some more muffler bolts for my TT Pro 46 engine. The existing muffler bols have the heads stripped out and I can no longer tighten them enough to keep the muffler on for more then a couple of minutes. I have found the bolts on another website as 3X40 cap head screws. My question is are these bolts from McMaster Carr the same thread type etc...
