Would there be any problem in using hex head bolts in place of the square head? It looks like a hex head will fit fine. For front wheels, should I buy Grade 5 or Grade 8? I'm guessing 8.

They also used to (well maybe they still do) make 8 point sockets just for square fasteners.   [Reply]   [No Email]

The higher the grade the more likely they break and not bend. So grade 5 would be plenty or go back with 2. Hex or square depends upon if you are using a wrench or socket. Tight squares are ok if you can get a wrench on them but anything recessed just about takes a socket. You also need to look at the recommended torque before making your decision.   [Reply]   [No Email]

I have a friend that is a salesman for granger supply that told me back last Dec.that the quality in the steel in bolts today are not what it was 20 years ago. Thats because 90%, yes I said 90 comes out of china. Today a china grade 8 bolt is NOT as strong as a 5 made in the US 15-20 years ago. It's sad but I guess we just have to keep buying junk out of china.   [Reply]   [No Email]

And Grade 5 vs 8? in reply to Brandon Frazier, 11-04-2009 21:00:55   Interesting to see that McMaster has gone back to Grade 5 on their square-heads. There were a few years there that they were all Grade 2. Learned that the hard way. (Is that a pun? :roll: ) The plain bolts they sell are unrated, but the zinc-plated are Grade 5, which should be plenty for Mike's purposes. I had the good/bad fortune when I was in Ohio to live just about 6 minutes from the McMaster-Carr will-call desk. Handy, but costly.   [Reply]   [No Email]

Less metal contact. McMaster Carr carries them and are reasonable   [Reply]   [No Email]

Grade 5 bolts will do the job. Grade 8 are stronger but cost more, it s your money. The correct poliece will want square head bolts and they work better because you don t have to hold the head. I don t ever remember seeing Grade markings on square head bolts, but I could be wrong.   [Reply]   [No Email]

Using a screw driver or pry bar on the back side and a air tool on the front is not fun. I changed them out to square heads and much easier to deal with.   [Reply]   [No Email]
