Mein Auto: 02 BMW 525i M54 automatic
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?
2002 525i => Seats => Front seat => SEAT FRAME W.ACTUATORS
- Parts diagram line #11 Fillister-head screw M4X10, #07146977086, $0.48
- Parts diagram line #10 Clip, #52101873544 $0.20

EDIT:
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.
