I'm in the middle of tearing apart my engine to replace the timing chain guides, and I've read on the forum that sometimes the crank pulley hex socket screws can shear.
so I decided to go ahead and replace the six of them with new screws. this began a journey into learning about hex socket screws. so then I started searching online for hex screws, and I stumbled upon this: score! the size I need in 12.9 strength, at $0.30 a piece! I only need 6 of them, so if anyone else is planning on having their crank pulley off in the near future, PM me and I'll ship some to you.
