![]() 2929 forum posts 41 photos | Jamie, this is a forged upset head bolt and is designed to take a lot of pressure. If you need a longer bolt then you need to copy the style and design. It can be made from stock materiel, ensure you incorporate the shouldered diameter. Stainless steel would be fine to use and in that diameter is readily available from stockists. I would not use studding as the plain shank of the bolt is there to stop fretting when in place. Studding with the thread crests will cut into the crankcase through flexing and vibration. M/cycle frames flex, so movement is a certainty. Clive |

1723 forum posts | Washer head bolts and nuts should be available from the specialist "Motor Cycle Stainless Steel Fastenings" (Look it up on Bing or whatever, there are loads) suppliers. I've used "Custom Fastners" in the past. NB. When assembling Stainless Nuts and bolts you MUST apply a lubricant to the thread BEFORE assembly. "Copperslip" is recommended, otherwise you will learn another word (Besides Anglo - Saxon) - - Galling.
