    The bolts are a good value. I bought them for headers. The heads are 3/8" 12 point, flanged. Only 10 but I have accessory studs, one on each side. They are new and appear to be of good quality. Made in Taiwan. Ordered as gr.8, they do not have the SAE 6 marks, but do have some identification on the heads. I believe they are as stated and I'm happy with the choice. I have bought from this seller before.
