I’m new around here and have a silly question: I need to reinstall my luggage racks and several of the bolts are pretty rusty. I went to the hardware store to get all new stainless steel bolts and upon arriving home it occurred to me: perhaps stainless won’t be strong enough… There are markings on the heads of the OEM bolts, and it does look like grade 8 markings … so I’m guessing stainless isn’t strong enough and I need to go back to the hardware store after work tonight? Also, any thought about using anti-seize to mitigate corrosion? I do not intend to leave the luggage on, I only want it on for multi-day trips, so I’d rather not use locktite. HOWEVER I would also rather not have the luggage racks rattle themselves free on a random remote highway while I’m cruising 70mph singing Borne Free at the top of my lungs… |

blue loctite is your friend. id probably not tap the threads, but maybe chase them with a thread chaser or make one with a spare bolt https://youtu.be/pfPm1W89TO0 |

If you're in a vibration or weight situation then stainless will work for a while but the bolts will stretch and work harden over time. If nuts are required then stainless nylocks will hold up. Plated grade 5 or 8 would be best. I usually use plated hardware with the stainless nylocks. Never had an issue but stainless bolts are just too soft. |

Another problem with stainless is sometimes the threads tend to seize either on assembly or disassembly leaving you with junk that has to be cut off. Not so much of a problem on large bolts but had this happen a lot on smaller screws and nuts. As a side note, loctite is a sealer/rust preventative that helps protect the threads as well as vibration resistance. I would stick with quality plated bolts and screws. |

Yea, stainless on stainless will gall and seize in a heartbeat. If you do use stainless on stainless, apply anti-seize before assembly. |

Late to the party, but - you're talking about a luggage rack - Stainless will be plenty strong enough. Definitely use threadlock. |
