DESCRIPTION:
Metolius added a transverse taper and silicon-bronze to the revolutionary Curve Nut shape to give these mini-nuts tenacious bite in each and every placement. The finest materials, combined with a patented shape, give you a powerful tool for protecting micro-sized fissures. Silicon bronze is the perfect material (although very costly) as it exhibits high strength, yet is still soft enough to let the nut bite into the rock’s surface and seat into position with maximum holding power. Additionally, on larger sizes, curves were introduced into the faces of the Astro Nuts, giving them a massive placement advantage over regular, straight-sided pieces.
