Bomber micro nuts with Curve Nut shape for extra holding power

Metolius took the same revolutionary shape of the Curve Nuts and applied it to these tiny titans. Metolius chose silicon-bronze because it exhibits the perfect blend of hardness and shear strength. This, combined with a patented Curve Nut shape (modified with a slight transverse taper), gives you micro gear which is easy to visually monitor and sets up the bomber triangulation necessary for a solid placement. They are awesome in flares and pin scars.

Astro Nuts are sold individually or in sets designated for aid climbing (sizes 1, 2, 3, 4, & 5) and free climbing (sizes 6, 7, 8, 9, & 10).
