I will be changing out the Factory Torx Bolts on My Derby Cover with Hex Head Bolts which will make it easier to remove them, I am using these 1/4"-20 x 5/8"

Part # 0185236 www.fastenal.com

 

Sounds like a Plan to me I have always gone to Allen Heads myself .. But anything beats them Stinking Torx...

 

I use stainless steel allen head bolts in my derby covers. They look as good as chrome ones but stronger, less chance of buggering up the allen wrench hole.

 

Lowes has a decent selection. I change out every torx i remove.

 

Ace Hardware has an unbelievable selection of stainless steel and chrome button heads, allen heads and hex heads.

 

Any issues with torquing up the torx heads versus the allen head cap screws, or the stainless steel galling in the threads?

My inclination would be to go with the stainless cap screws, in grade 8 for the hardness, unless I heard otherwise.

 

Stainless bolts aren't rated in grades.
The best stainless bolts made have the threads pressed in, as opposed to being cut in.

I replaced EVERY bolt on my bike to the Diamond 12 pointers. Awesome bolts, in my opinion...but get your heart right, they don't come cheap.

 

Outstanding information. I think I knew about not grading of SS bolts, from the distant past.

The article is very interesting and the design of the bolts seems to be exceptional. Very impressive strength numbers for the SS and the geometry of the heads gives extra web thickness at the shoulder.

I hesitate to ask, but I am guessing they are $15 - $20 each? Between roll threading, testing, polishing...that is a lot of labor for each fastener.

 

You can buy an entire drivetrain kit for around $600.
I wouldn't buy direct from them either.
There are indy's, like M&M Cycle, that gives huge discounts.

I hesitate to say, I have upwards $1800 in bolts on my scoot...but like I said, I changed all of them.

Diamond is coming out with some new 12 point axles, too. Can't wait to see those!

 

Just be careful not to overtighten them,of course there are Helicoils.Good Luck
