BELOMI Motorcycle Fairing Bolt Kit, 177pcs M5 M6 Motorcycle Windscreen Screws, Aluminum Fasteners Fairing Bolts Nut Clips Kit, Mounting Kits Washers Nuts Screws Assortment for Sport Bikes (Blue)

I use them for looks. Would not use the on my engine.

The bolts split in half as you screw them in. Five of them so far. One is now left inside and I have to find a way to take it out and we all know how challenging that is. Regretful purchase

Really golden colored bolt. Nice kit. Has just about everything you need to change the existing bolts to a different color. Good effect.

Bolt broke when tightening down with tool that was provided. Cheap aluminum, do not buy, had to be drilled out.

I had to replace the power windshield on a Honda ST1300, and picked up this kit because I knew after 15 years there were going to be several fasteners needing replacement.The assortment was just OK, the 4mm and 5mm hex head bolts came in a couple different lengths, but the difference was minimal, and I still had to trim a few.The biggest issue was the very inconsistent tensile strength.As you can see, one of the bolt heads snapped as I was tightening.I was using a hand driver and barely made contact when it snapped.You can also see by the picture of the stud, as I was preparing to Easy-Out the stud, when the drill bit into the broken piece, that caused it to spin out the back end of the frame.The head broke off with almost zero torque.Some of the bolts worked great, but based on the number of pieces that broke used vs total quantity I would estimate a minimum 10% fail.The threads were not always metric, as you can see from another picture, the bolt cross-threaded due to a wrong thread bolt added to the supposed metric kit.The listing includes Honda ST1300, but this kit was obviously not designed for the bike.It simply has some similar bolts, so the advertising is misleading.I gave it three stars because even if there's a 40% defective rate there are some useful and unique fasteners.I happen to have eight motorcycles, and plan to use these for non-critical locations only.I certainly would not use these on anything that would result in a catastrophic event if a bolt decided to suddenly fail.On the good side the bolts are 4mm and 5mm, but even a couple hex heads stripped out with minimal pressure.For shoulder bolts they give some collars that will slide over the bolt to secure faring's and such.Unfortunately, the slide on collars are far too long for most of the applications.In summary, it pretty much sucks, and don't get this if you don't already have a decent assortment of standard metric hardware, and without doubt DO NOT use any of these to hold down a brake oil revivor, caliper, or even a cable that would get caught in a wheel were it to suddenly come loose.Spend the money on a factory or brand name kit.I didn't notice it was an unknown until I received it.It's one of those impulsive buys that may never get used again.
