Why reinvent the ARNOLD "wheel", or should I say alloy crankarm bolts when you can buy currently available substitutes made by SRP???
Don't know how much they sell for, but fairly certain they are still availa ble. I know I have a few pair anodized in different colors that were pur chased on eBay in a shop case of assorted various alloy SRP superlight bolt s. I used lye drain cleaner crystals to remove some of the crazy anodize d colors!
May just be easier to find and buy the SRPs. If memory serves me correct ly, they have the same 14mm hex heads that the gold anodized Arnold bolts h ad.
