Pannier Rack Bolts: Threadlock vs Copaslip

[Distorted Vision]

The heads of the hex bolts fixing my pannier rack to the bike frame have light rust on them. They were fitted at my LBS so I've ordered some A2 black stainless steel ones.

I was wondering if I should use Threadlocker or prevent them coming loose or Copaslip to prevent them seizing?

I would use Copaslip to prevent the stainless steel reacting with the alluminium frame.

I have just used grease for ever and never had a bolt undo. Checking bolts as part of your routines is good practice anyway.

They are black A2 bolts so I thought electrolytic corrosion wasn't an issue?

 

[Distorted Vision]

Copaslip it is then!

As YukonBoy, just grease them and check once in a while. Best practice.

You could also use a none slip washer with the coppaslip

Threadlock will also act as an anti seize. I'd use moly anti seize myself, but I'm sure copper would be fine.

Use an anti rotation star washer. Rack bolts can come out under some weird combination of conditions.

Mix 2 parts coppaslip, with 1/2 part Locktite 312 and 1/2 part Loctite 446. Our into shaker and shake anti-clockwise. Then apply to threads with a badger-hair brush and torque to 5.2 NM.

For god's sake. Go for a ride and drink a beer.

5.2 NM wet ? Dry torque would be around 5.2nm so that may go a bit too tight.

Figures are set dry.
Not to mention the £15 for all them locktights,it's a bike rack!!

You forgot to fabricate the electrolytic reaction divining tool, so that the magic mix can be properly targeted.

Personally I'd always cause a Chinese virgin hair brush.

First, catch your badger

Bog-standard grease here. I once had to tediously drill out and re-tap the hole for a mudguard bolt which snapped, but I think I forgot to grease that one.
