Replace PS bolt with SS in Powers 5 Piece?
|
Has anyone ever replaced the bolt and washer in a Plated Steel powers 5 piece with a 304 SS bolt and washer? You can get those Parts for $0.80. |

the remaining plated parts would likely corrode at a faster rate, although how much faster it is hard to say. the stainless components would be fairly similar in size to the remaining plated parts, so the galvanic charge density wouldn't be that high. good question. probably wouldn't be the best thing, or the worst thing. |

If you are placing plated steel bolts PLACE plated steel hangers. Mixing types and grades of steel can promote deterioration. A stainless hanger will not indicate possible corrosion of the plated steel bolt. |

I know all about "don't mix your metals". or Again, just DON'T MIX your metals. Seeing that I can buy the bolt and washer in 316 SS for $0.80, it's MADDENING that the rest of a Powers 5 Piece (sleeves and cone) cost $8 or more !! |
|
another option would be to go all stainless except for the washer. using a plated washer would make a small non-structural, "sacrificial" anode. |

stainless powers bolts do not cost $8. |

Source is widely mentioned as the cheapest around. We're talking about soft rock bolts here. You can get ones for granite as low as $4.60 without shipping. |

The only place corrosion will start and bolt integrity will be diminished is at the cone. Provided you used all SS replacement parts with the exception of the cone. |

I don't like the idear at all. How will anyone know the whole bolt placement isn't stainless?? It'll be a ticking time bomb with no indication that its a POS. |

You should take it upon yourself to replace the Plated junk with SS, people will praise you and the bolts won't need to be replaced for probably 80 years. Bottom line, You would not improve the life expectancy of the placement/bolt with the method you listed in the OP.Yep. Pretty much everything I'm pulling out of the rock and have seen online indicates the CONE rots out first along with the threads. The PS ones can look great on the surface and be junk underneath. Even in "dry" areas such as TX. There are claims down here that it's "too dry" to warrant SS but nearly everything I've seen tells me "no way". When it does rain the Limestone holds the water just fine and BAM, subsurface corrosion. Rusted Wedge Bolt This was junk left behind. Hardware crap. Rusted 5 piece This bolt was in the rock for probably 5-10 years. Nearly all my replacement work has been to use a SS Glue In. Good for a LONG while and CHEAPER than a Powers 5 Piece! |

There is rust then there is corrosion. In the photos all I see is rust which is OK and probably doesn't weaken the bolt at all. |
