Do you really want alloy bolts? Aluminium is very soft, what size do you need I may be able to make you some

Slightly off topic somethingelsie, but I've always wondered how the hexagon recess is put into allen key bolts. How is it done?
Swifty, please don't think I am tarring you with the same brush, but someone I used to work with insisted on using aluminium bolts everywhere on his bike. This included holding on things such as disks ans sprockets which IMO is not a good idea.

Hi, Sorry to sound a bit "annal".....when I was an apprentice I used to get into trouble for calling them "allen bolts"..... the correct term I was always told is....CAP SCREWS. Im not sure how they are made, never seen it done, but I am guessing they are made with a die and are stamped, punched or made using a machine called an "upsetter"  , wheather they are done hot or cold, I also do not know. Would be interesting to find out all the same. Iv seen this discussion before about using stainless/alternative bolts to hold discs and calipers on. Most times the disc bolts and caliper bolts are fitted into tapped holes on your wheel or caliper.....which are usualy also made of aluminium/alloy. I was told that the alloy in the wheel or caliper would shear/break before a stainless bolt ever did, not too sure about aluminium bolts though?....im sure a "clever" person could work it all out using tensile strengths and shear loading etc etc etc...yawn. Im away out now to do some more running in miles on my LC, seeing as its not raining.....yet. steven. |

Aluminium is lighter, Titanium is stronger. If you don't need the strength then Aluminium is a better choice beacuse it's lighter and cheaper. |

Hex is broached into the head, using a wobble broach tool. I have made for my f1 titanium disc bolts I'll try and attach a photo later.. I can make most normal nuts and bolts out of titanium, you can either go through me or contact Norbo an he can get in touch with me for your requirements

somethingelsie, being an engineer myself the hex recess in socket cap/button head screws has always got me wondering how it's done. Along with pyramid tea bags.
A picture of the actual broaching process would be far more interesting IMO than the finished article.

Hi Dave, I could make the raw material bolts but as of yet no means I do anodising unfortunately.

, wheather they are done hot or cold, I also do not know.
