Anodized nuts and bolts sets question

Hey

I'm looking to get a set of anodized nuts and bolts for my 748.

Any good leads or websites on a good cheap set?

Should I go with aluminum or steel? I figure steel would be better in terms of strength. I don't mind the weight much


thanks

Purely talking strength and durability, steel is the way to go, it is twice as strong as aluminum and Ti, as a material. Alum has to be changed out periodicly, bc it will eventually break, limited fatigue life, just the way alum is. Steel wont. Ti has a fatigue life too, but longer than alum.

All are good, depends how much and how hard you ride. If you dont mind replacing once a year ish if you ride a lot, then its cool.

Ah well...no. Well made Ti bolts are plenty strong for most applications. I have used Aluminum bolts in non stressed areas for over 15 years without one failure.

From Met Tec;

All of our bolts are made with aircraft grade Titanium Alloy. One of the outstanding benefits of Mettec bolts is that we forge the heads for superior strength. The threads are then rolled to produce greater fatigue strength and reduce galling.

Our bolts exceed minimum Ultimate Tensile Strength (UTS) of 120,000 psi. Mettec can also make titanium bolts that exceed 160,000 psi in Ultimate Tensile Strength (UTS). Both styles of bolts conform to DIN and ASTM specifications. Titanium bolts can replace both grade 5 and grade 8 steel bolts which have minimum UTS requirements of 120,000 psi and 150,000 psi respectively. Metric bolts with an 8.8 rating can be replaced with titanium while bolts with a 10.9 rating can sometimes be replaced with titanium depending on intended use. Any bolts with a rating over 10.9 rating should not be replaced with titanium.

I have a mix of aluminium and titanium nuts bolts etc
from pro-bolt, lightech,Factory racing,nylon & alloys ltd.
Earls for aluminium plugs.
just made a note of the size, thread etc then ordered the different
bits as required you can get most items from pro-bolt but not all.

The weight saved is minimal, and I wouldn't think of using aluminum where failure could be dangerous to oneself or others. Think of aluminum fasteners as being grade zero and you won't be far off. One could save more weight by cutting out pizzas and nachos for awhile.

Mettec makes some axels and stuff too. If you are willing to take the bolts out measure them and order only what you want it should be cheaper than buying a kit. I have been working on finding a company that makes titanium spline drive metric bolts to replace all the hardware on my bike.

This is a supplier index website, its pretty cool. http://www.thomasnet.com/products/aerospace-bolts-95955308-1.html

Aluminum screws are weak. I wouldn't put them on anything wear strength matters, i.e. motormounts, sprocket bolts, shock bolts, subframes, anything to do with your forks, controls or clipons, now that you mention it, I wouldn't put them on anything. Want your turn signals to fall off? Seat? Fairing panels? Well, maybe the screws that hold the windshield to the fairing.

Anyone who would like a quick, intelligent and understandable course in fastener engineering should look for a copy of "Engineer to Win" by Carroll Smith. It should be available through Amazon or bookfinder.com. Smith was Carroll Shelby's crew chief, and this book is a collection of wisdom gained through years of racing experience.
