I came here after a long time away to find the bolt sizes for my seat cover since both my bolts and all four Christmas tree clips appear to be missing.
I wonder if we can just find a metric Phillips head bolt to replace the two T30 bolts?
Q: Can someone explain how to cross reference a M4x10 (T30 Torx) bolt to a standard Phillips head metric bolt at Home Depot?

I mean, I know it's 4mm in diameter and 10mm long - but how does 'that' tell us what threads it uses?

- Parts diagram line #11 Fillister-head screw M4X10, #07146977086, $0.48
- Parts diagram line #10 Clip, #52101873544 $0.20
I just called the local San Jose BMW dealership who has the clips in stock for $1.94 each but not the bolts which are $2.20 each.
(BTW, I've never found the local BMW dealership here in Silicon Valley NOT to be the most expensive for anything - even trivial parts like these.)
Note: Googling, I find there is M4x10x0.7 (which is a course thread) and M4x10x0.5 (which is a fine thread).
I just realized I can remove the bolt on the passenger seat and just match 'that' at Home Depot.
Each repair should invariably add to our knowledge base by the process of inexorable incrementalism.
Your job, in return, is to read the suggested threads, where the best people will always add value to those threads, either by pictures or by descriptions, so the next person with the same problem stands on your shoulders.
