Fair Wind Fasteners supplies only the best quality in hard-to-find fin neck bolts. As always, they are full bodied with cut threads and cold pressed heads. Originally designed by the "Wizard of Bristol" Nathanael Herreshoff, the fins underneath the countersunk head on these bolts will hold them securely and prevent them from spinning when tightened down onto a wooden surface. 

These fin neck bolts have a flat head, as seen in the photo.

Spec: ANSI/ASME B18.5

Haven 12 1/2 Keel Bolts

The fin neck bolts preserve more thickness in the wood structure than carriage bolts and they’re cheaper. I had started to try to forge my own fin neck bolts, but I realized it was better to buy them and I’m glad I did. The forging die that we made didn’t have the sharp angled fins that would dig into the wood as good as the ones from Fairwinds do. I’m sure we’ll be buying more fasteners for our project from Fairwinds Fasteners. Also appreciate the counterbore advice from Rob.
