| I personally wouldn't use a bolt with FNL or WMJ on the head in an application where your life or somebody elses depends on it. If you ask for Infasco they generally have it in common sizes. Always look out for bolts that look like the threads were lathe cut- which you do see out there sometimes. All in all fastenal is pretty good I don't mean to imply they are trying to sell junk. They have access to a wide variety of brands. Every farmer should aquaint themselves with different head markings. I believe every manufacturer has a unique mark. There is a Chinese bolt that has a hollow triangle that I believe is designed to mislead into thinking it is Infasco which is a solid triangle. | |
