Thanks to a completely revolutionary design we created with renowned gear designer Greg Lowe, Tri-Nuts offer true flared-crack protection from a passive piece for the first time in history! Flaring pin scars, bottoming seams, incipient cracks ... these nuts protect previously unprotectable features!

Tri-Nuts also work well in typical placements too. Because of their shape, each Tri-Nut fits three distinct crack sizes, providing more placement opportunities than normal nuts.

Ever find out you were off by one size after you pull a nut from your rack? You have to go back to the rack, figure out which nut is the next size up or down and then try to fiddle that piece into the crack. With Tri-Nuts, if you pick the wrong piece the first time, just rotate the nut to find that perfect fit!

Sizes 0-8 are built from machined steel, and then brazed to a single strand of galvanized aircraft steel cable. The mono-cable design permits incredible flexibility, and a truly low-profile design that is easy to slot through the botoms of pin-scars and narrow features.

Sizes 9-14 are machined from aluminum for weight savings and swaged with aircraft steel cables.

That's not all: notice the crown at the top of each nut. It provides stability and strength in marginal placements. And those little divots in each face means you can adjust the placement perfectly around crystalline features and other irregularities.
