These custom made bolts sell at $3 EACH. Seems expensive but its actually super cheap for 6/4 Titanium. They are super light, super strong and will not corrode.
We only made bolts, and these come with stainless steel nuts.
These bolt heads are made shallower so they sink in easily, while still having a wide head so they stay tight and wont sink in too deep.
The heads are Hex (Allen) drives.
