Though I did not have 20 or so of the 2024-T4 bolts and lock washers to replace the old oil pan fasteners, I figured to show 'em before they screw into the block using lock washers and a very liberal amount of purple lock tite. The 17 pieces here weighed 2.55 ounces compared to just (one) steel pan bolt weighing in at.0.40 ounces.
Lets not forget the timing cover bolts.
