Looking at my torque chart that specs a general torque for an M8 x 1.25 bolt is 20 Lbs. That’s what I used.

Yes. I was lucky

You should have been good. It may have just been a "bad" bolt, but probably is a cheezy built to a price knock off with 8.8 stamped on the head. It's a crap shoot any more with hardware. There was even knock off AN hardware floating around a few years ago, but I think that has been sorted out by now.

If you want good fasteners , go to Fastenal . If you go to an automotive parts store , you follow them to the bin and look to see if it is a good brand before you use it . This Chinese s++t is taking over and I DON'T like it one f'ing bit .  What's bad is , the Fastenal stuff is Chinese too .

Almost everything is. :oldgit: Here's the deal. The Chinese are perfectly capable of making a $5 bolt. However, if the retailer wants a $1 bolt that they can sell at $3, they can make that, too. If you want, they can make a 29cent bolt that you can sell for $2 to unsuspecting customers. They don't care, they just make what the retailer wants at the price they are willing to pay.

I've said for years that if we had enough rope we'd hang ourselves. Now, we've sent all the rope making machinery..and the expertise to run it.. to China. As my favorite actor Babe the Pig  :D said, "That's the way life is."

If there is a Caterpillar dealership near , get fasteners from them . I have been told , they manufacture them and say CAT on the bolt head . Also Lawson is an excellent vendor .

Does Caterpillar make metric fasteners?  

I think the simple thing is to look for the 12.9 standard marked on the fasteners.  You can get them at Lowes and probably Ace.  That's where I get all of my nuts and bolts.  I've tried Fastenal and they seldom have what I need there, so I never go back.  You can also go to a specialist store for industrial-supplied fasteners, usually you have a minimum like $20 for a purchase.  For sure you can get 12.9 quality at Lowes but they may go for more than a buck a pair for just some 20mm M8 like I had to get got my Duc luggage rack mounts.

Rather than make a guess about quality, just look for the marked standards before you purchase.

Yes , Cat has metric stuff too . 

Fastenal depends on the area . The Paducah store is almost mail order and The one in Calvert City is incredible . You can't get your sentence finished before a salesman says "how many ?"

 The pic of the stretched bolt reminds me of Suzuki fasteners of the late 70s-early 80s.  Terrible !    I keep new stuff , I keep old stuff of everything I tear down . Last week I took to the scrap yard a 55 gallon drum of SAE stuff , carriage head & what-not of standard stuff.  I think I have a hoarding complex for metric (and just about everything) stuff ?

An engineer for a major riding mower manufacturer tells a story about when they outsourced to China, the first container of mowers showed up with all the blades lying in the bottom of the crates.  Turns out the Chinese noticed the six lines on the bolt heads (indicating Grade 8) and diligently cut the lines into the heads of the bolts they had on hand . . . :huh:

If time isn't critical, ordering from Fastenal online can get you exactly what you want, and I've found their customer service to be very helpful. Like you, I tend to keep a bunch of fasteners, old and new, on hand, so when I put in an order, I just get a bunch of stuff "in case."

If you want really excellent, no excuses good stuff, (I haven't checked ARP), RaceBoltUK has absolutely top shelf stuff in SS, Ti and even alloy for less stressed tasks. You can choose your head style and drilled for safety wire, etc. Last order it was one week  - seven days - from mouse click to doorbell here on the west coast of the US. Incredible. And the lucky blokes in the UK get it sent for free.

The crappy little Do it Best Center on York Boulevard in Los Angeles has an amazing selection of metric fasteners. Wish I had that here...!

Hello,

I am a lucky man : I found the original Moto Guzzi luggage for V11, in mint condition (never used for 20 years).

I mounted it on the bike...and I am very happy with the result !
