 Topic: Swim platform boltsPosted: June-15-2009 at 1:12pm |

Hi,
I have a 78SN and the swim platform is held on by some very rusty looking bolts. As I have the fuel tank out at the moment Id like to change those rusty bolts and I was wondering why they aren't stainless? were they grade 5 or 8? I will be ok with some new stainless bolts right? |

Good question. They definitely should be stainless. I don't know about what grade, I would think 5 would work. Make sure you seal the thru-holes with 3M 5200 when you put the new bolts thru. |

Stainless bolts aren't available in multiple tensile grades like carbon steel bolts are. Basically you will have a choice of ether 316 or 18-8 stainless. These are stainless alloys and really relate to the corrosion resistance. Both are rated at a min. tensile of 70,000 psi which is slightly better than a grade 2 carbon steel bolt. Go with the 18-8 from the hardware store and you'll be fine - you aren't building a pressure vessel here!!! |

Eric, I don't think your analogy with the paint is the greatest. The thickest normal paints dry film thickness is only about 4 mils (.004")!!!! |
