I'm trying to by some threaded stock from Fastener Mart but I'm not meeting their minimum purchase. What are some bolts/nuts that I need spares on? I've already got a box of exhaust nuts. I snapped one on the rear valve cover bolts w/ 20 ft/lbs of torque. They seem like good candidates for replacement. Anyone know the size? I'm guessing M8-1.25x40mm. What are the rest of the valve cover bolts? M6-1.0x40mm?

 

I'd get a variety of M6 and M8 bolts. It seems like I'm always looking for something to make a bracket or hold something new onto my car.

 

Mazda Likes to use 10 mm x 1.25 bolts/fasteners. If they have some, get 'em. They are not always easy to find. 6mm and 8 mm are also common to the Miatas as well.
