I would recommend when anyone gets their Grenadier they take off these 3 torque screws while at home and lightly coat them with Ultra Tuf-Gel and then install them again. That will prevent them from seizing up and any galvanic corrosion. You can buy it direct from Ultra Tuf-Gel or on Amazon. Expensive, however it is the best, especially if you are in a marine or coastal environment. It is used extensively in the marine industry. There may be other fitting, screws and bolts that are either similar metal or dissimilar metals where using this in advance can save you hours of pain and dollars later by preventing seizing and galvanic corrosion. A little of this goes along way, so it is worth the investment. Be careful to not over torque when using any lubricant, as the torque settings will change. From what I have read, best to not use on wheel studs or wheel nuts as you can snap a stud and may not have as secure tightening and hold as without it. I have used it on my 2020 Defender Rhino rack. I had an experience with some surf racks I put on a prior Range Rover Sport and when I went to sell it, I wanted to take them off and put them on my new vehicle. For the life of me I could not get them off the vehicle and had to let them go to the new buyer. Been using Ultra Tuf-Gel on everything since. DaBull
