Bolts are nice
Bolts are nice. Washer ID seems too big. I bought new SS washers from Lowes.

Worked as described; missing a washer
Used these to secure a Victor Jr. Edelbrock intake to a small block Chevy. The packaging was slightly damaged and one of the washers was missing, but other than that, they were perfect for the job.

Outstanding Bolt
The average socket will not work with these. 3/8 socket with the same 12pt pattern must be used. Makes this nice because the average thief doesn't carry this socket. Bolts look amazing as well. I recommend these if you are installing an aluminum manifold because the bolts and the washers are hardened. Just be careful when working with aluminum heads.

Great hardware but...
amazon warehouse did it again. Two missing washers with the intake manifold mounting blots. Low torque so I will just use off the shelf washers. Someone need to learn how to count at the warehouse. The bolts seem to very good as are the washers that did arrive.
