How to tell if a bolt is safe?
|
So I was climbing last weekend at a new crag and doing some routes that are harder for me, and I was taking a lot. After weighting the system a lot of the bolts would be much looser than before I weighted them. One route in particular kinda spooked me, after I lowered, (I had left a few draws in for directionals) my buddy was following and when he grabbed the first draw the nut, washer and hanger fell off the bolt in his hand. Is this normal or am I justified in being a bit spooked? Kinda makes me appreciate being able to place my own gear tbh, not having to worry about weather or not a hanger is going to fall off randomly. |

Is this crag around here? It might be nice to state the name, so we can avoid it... |

There are a lot of resources on this including through the Access Fund and American Safe Climbing Association. There are also a lot of folks in the front range area that do bolt stewardship. If you post the crag/routes one of us can go check it out and replace bad bolts, or more likely just tighten the nuts. if it's just a loose nut that's easy to fix. if the bolt itself is loosening, thats sketchy. Ultimately no bolt is 100% |

Charlie, it sounds like you broke the bolts from too much hang-doggin. Start climbing harder and don't put so much weight on those poor bolts. You know people pay for those right? Kids these days.... |

My go-to is fresh virgins blood diluted in holy water... squirt some on the point and wait 5 minutes. If the blood/water mixture starts to steam and boil off the bolt then you should probably avoid it. Otherwise take them whips... it also is great for de-rusting those babies. |

Based on his tick history I'm going with: All Locations > Colorado > Ft Collins > Lory SP > Arthur's Rock > Overlook > The Giggle Maker "1st hangar fell off" |

Sounds like the installer was incompetent and needs a lesson on placing bolts and a torque wrench and maybe the right sized drill bit and a hole brush and blow tube.. Who knows what is the matter. It could be the nuts are just loose and most of the previous poster think. It could be much worse. |

I’m not familiar with the area, but based on the crag description, and the recent time of addition to MP, I’m guessing that it is a new climbing area, with relatively-recently bolted routes. |

i never understood why people who bolt dont toss the nut that comes with the bolt and just buy a handfull of grade 8 hardened stop nuts at someplace like tractor supply. they wont back off the stud even if the bolt loosens in the rock a tad, youll notice hanger spin instead of it falling off completely. |

Grade 8 steel is carbon steel, and shouldn’t go on stainless bolts. You can probably get the same nut in stainless, but it would be pricey. A properly torqued bolt shouldn’t readily loosen. |

I'm not really sure what is normal vs not normal. The rock in this area is quite crumbly and I believe most of the bolts were beyond hand tight, however after taking on one it would loosen up and need to be re-tightened. The area is basically brand new so I'm not sure if's just one of those things that has to be done with new bolts or not. A lot of these routes have less than ten ticks on them. |

Don´t use locknuts on bolts for climbing. |

You ever wonder why not one single climbing distributor of wedge bolts or manufacturer of wedge bolts does this? Occam's razor: Because its a bad idea. |

Totally normal for hangers to fall off randomly. Climb on |

Good lord, loose nuts and spinning hangers are not necessarily signs that the "bolts are loose." |

Daniel Winder wrote: Totally normal for hangers to fall off randomly. Climb onYou're right, I'll try a few of the newer methods I've seen online. Idk, I am aware that after tensioning a bolt there is a bit of relaxation, so it is possible that when yarding hard on a new bolt / hanger that could create a spinner and loose nut. If that's the case, I'm not all too worried, just cinch er down and keep climbing. What I'm worried about is if that isn't normal, it could mean that the expansion bolt is shifting around in the rock. Since this area has some pretty crumbly stuff it wouldn't totally surprise me, but I don't actually know that much about it, so I don't want to assume one way or the other. |
