Are there different grades of metric bolts? I need longer spindle bolts, and I want the right strength bolt.

I took a SAE fastener class last year and we got a presentation from Spiralock during the class. The theory makes sense and it is used in some applications, but in the car industry the extra cost of using this thread pattern is prohibitive. Generally, a manufacturing plant doesn't want to worry about sourcing new thread taps and the like, especially not ones that are more expensive than what they currently use that are also working just fine.
Besides just rolling threads there is also a MJ thread designation that basically has a larger radius at the root of the thread. This makes the bolt even stronger and is used for many engine fasteners, especially rod bolts. |
