Installing a new derby cover, HD instructions call for blue loctite. I know from past experience derby covers and points covers can be a pain to remove because of corrosion. I am leaning towards using anti seize mostly for derby cover which needs to be removed every oil change. Any thoughts which would be best. Than again why not use stainless screws?

I use loctite brand stick thread sealer. It gives some locking ability but won't lock so hard to strip those POS torq heads out.

It's always better to fight to get it off when you want it to come off , than it come loose when you don't.
Break them loose when the motor is still hot.
PS. switch back to allen head.

I investigated this to death once. Forget all the details but went with Diamond Engineering stainless 12 point screws and their recommendation which I remember agree with all research. Their 12 point engine screw kit is high dollar, $300 I think but results look great.

i've always used anti-seize on the derby cover bolts. never had a problem, except for the first time that i changed the oil on my 2002 sportster. that's when i started using never seize :D.....

also, you don't have to torque the bejeezus out of them either. it is not high pressure behind it, so snug is good enough. the torque spec used to be 84 - 107 IN/LBs, don't know if that's changed in the last few years....

I use Stainless Steel Allen Head Screws and I would suggest that you do the same because it makes the removal and installation of the derby cover much easier. I don't use loctite or anti seize on the derby cover screws and never had any problems.

I'm a Lok -tite junkie but when it comes to the derby cover I use anti-seize and torque to factory specs without any issue. No leaks and easy enough to get the screws out every time.

Had no idea that they had a stick, I assume it's just less messy?
Yes less messy, and you can scrap the threads across it to control the amount used. Thread sealer is what I use on all the small bolts. When I found this, I was actually looking for some purple Loctite, so I went to a Loctite booth in Daytona and they suggested the tread sealer.

On a Harley use the appropriate thread sealer red or blue on all bolts except axle nuts. Use anti-sieze on exhaust flange nuts and spark plugs. If done correctly, you won't be sorry and should ride many safe miles with nothing falling off.

Torx Screws

I don't use any kind of thread prep and never had a problem with the Torx fasteners. I also just snug them up and don't worry about using a torque wrench on them. Most guys use a T-25 to begin with and screw them up badly. Only things I use a torque wrench are the really critical fasteners like axle nuts, swing arm nuts, etc.
