POWER-STUD Wedge ss 3/8" : Anyone use these bolts?
|
Any reason these are too good to be true in hard limestone? |
|
Contact Kevin Daniels at Fixe Hardware and ask him. Kevin has years of experience with bolts used in climbing. |

You might check in the Bolting section of this forum and post questions there. Long as you don't mix metals (with these you'll need stainless hangers) I personally don't see why you couldn't use them. When I was in construction, I frequently had difficulty getting that design to catch and tighten up, but they were Red Heads and not Powers Rawl. and yeah, Kevin might have some input. |

Yes. These will work just fine. Although the countdown has begun until the glue-in argument and 5-piece argument comes into play. Thanks for the link. Gonna pick up a bunch. |
|
I've used them in basalt. |

See the links that I posted here: mountainproject.com/v/wedge… However, I completely agree that over drilling is still a good idea as a back up. |

Yeah, they're pretty common. I've placed a couple of them. You can get them from climbtech climbtechgear.com/climbhard/ See what nicelegs said above. |

I just looked up the strength. Depending on hardness and embedment, you'll get about 16 to 18 kN. |
|
If your limestone is overhanging or you expect tons of hard falls on the bolts, consider using 1/2" ones instead (bit less than $2 ea from same place). The 3/8" are, as stated above, on the weak side of acceptable. |

They are fine in hard rock. Probably more suited for hand-drilling in a wilderness area than bolting a sport crag. |
