M4 x 30mm
M4 x 30mm covers longer fixings in countersunk, pan and thumbscrew formats, so the head choice changes how the assembly finishes.
What changes between the head styles?
Countersunk heads sit flush, pan heads leave a rounded surface, and thumbscrews make longer hand-tightened fastening easier to adjust.
