Silicon Bronze Fin Neck Bolts

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.
