    got that right!!! Since they opened the Fastenal store here, I'm really spoiled. If they don't have what I need in stock the can have it within a couple days usually. They are now even starting to stock some grade 9 stuff... Expensive, but really nice quality..

    If you are assembling something that specifies grade 8, you cannot use grade 9 as it is not a real SAE standard. Grade 9 is a proprietary standard and does not necessarily have to meet or exceed the standards of grade 8. It may, but it does not have to.

    Pat, you should cut that bolt where it necks down and check for defects. Also, you need to find out who made the bolt and go after them. Very few bolts are made in the USA anymore, most are out of Taiwan. It's kind of hard for the SAE to regulate on them when they're half-way around the world.

    If I'm using a bolt that is load bearing or might have a bearing on safety - it does not come from TSC (99% Chinese made) Lowe's or Home Depot. I'll occasionally use one of their Gr8's in place of a Gr5, and their Gr5's in place of the CS Gr2's.

    Most of what I use are ARP(engine, for sure) McMaster-Carr or Fastenal - but even some of them are starting to be made off shore. With McMaster-Carr, you can order bolts based on the spec needed and is spelled out on-line. My experience with Fastenal is less because their local store is inconvenient and I find their on-line catalog not as easy to navigate.

    All good points and I would offer the following;

    1) It matters whether the bolt threads are lubricated or dry when torqueing.

    2) It also matters whether the bolt threads are brand new or worn in a tad.

    3) Even with name brand bolts it is possible to get a bad one on occasion.

    Not all bolt applications require clamping to 90% proof load so sometimes it is hard to find a bad one. If you are clamping to 90% proof load than 1 and 2 above are critical.

    well alot of guys buy for looks they like the gold plate on them. like said by Ireland child . step down on the bolts use the 8 were your would need a 5 grade bolt . on a cheap bolts? But they should not be any. i was talking about that same thing to a friend that day before i posted this .i felt this should be adressed for the guy that buys a bolt for a grade 8 bolt? and has all the good intensions for using it just for that a grade 8 bolt . so for that person this is a wake up call. i posted this for them . i did email TSC and told them that i did have many good photos of the bolt.i hope they will do some thing??? as for to go over the grade (past a grade 8) i am not a big fan of that if it is not at the right stretch you can have failure to. i have seen things move from the fasteners not QT to stretch.i look at the marking on the top of the bolts and do know abit on who is the maker but i guess this can be counterfeited to ?

    Obviously I'm not a fan of Chinese hardware which is based on my professional job experiences. GE made a bunch of gas tubines in the '90s with fuel gas and atomizing air flanges that were made in China. While the spec was supposedly followed, and tests done to ensure that they actually were met, several failed. GE had to issue a 'recall' of sorts and replace every flange (which included that particular section of lne as well) made by the Chinese - many millions of $$$$ later, the problem was fixed. I don't buy tools made in China either - except for possibly one time use items such as my ball/u-joint press. They just do not have control over their quality processes yet - they are where the Japanese were in the '50s and early '60s.

    I use grade 8 bolts for everything on my truck and boat. They cost more, but it's a heck of a lot harder to round or break them if they seize up (which they rarely do because I also use anti-seize). They are also more corrosion resistant than grade 5.

    I thought there's a reason for using 5gr & 8gr and why you wouldn't want to use one in place of the other! right?
