: I need some bolt size data

I am working on the design for a JK Hi-Lift Jack Hood Mount.

I am wondering if anyone can tell me the size of the 4 bolts that hold the hood to the hinge.

I need bolt size x thread pitch x length.

Yeah I have that info, let me run out to the shop real quick

M8-1.25 for dia and thread
stock bolts are about 20mm of thread and about 8mm of conical taper to the head surface (they're countersunk)

To bolt on 1/2" stock over the hinges, I used M8-1.25x40 allen head

Perfect, that's all I needed to know!

My bracket adds about 26mm to the mix, so probably 50mm long...
