Do you carry ball nuts on your trad rack?
If you've never used ball nuts, they're one of those weird-looking pieces of trad gear that can save the day on thin cracks.
Instead of cam lobes, they use a sliding steel ball that locks against a tapered body when weighted. They excel in placements where even micro cams won't fit, especially shallow seams and old pin scars.
That said, they're definitely not "plug and play." They need solid rock, the right crack geometry, and a careful placement. I always give them a gentle test before trusting one. When they're well placed, they're surprisingly confidence inspiring.
They're a niche tool, but if you climb older trad routes, aid, or thin crack lines, they're worth learning to use.
If you're interested in building confidence with gear placements, the American Alpine Institute's Learn to Lead program covers everything from passive protection and cams to advanced pieces like ball nuts, helping climbers develop the judgment needed to lead trad routes safely.
Do you carry ball nuts regularly, or do they mostly stay at the bottom of your rack?
