Same here, mine were M10s on the HDX stainless drop nerf step bars.I pulled the instructions from my GoRhino RB20's, looks like the ones for mounting to the cab are M10x35.
Mine too, but it was the smallest smear of Loctite which I covered with Never-Seize! =DThe bolts supplied with my Ford bords had loctite spots on them also.
Remember to reduce your torque value by 25% when using never seize because it's a lubricant.Mine too, but it was the smallest smear of Loctite which I covered with Never-Seize! =D
With lock washers, I'm not concerned. Plus I checked them recently and all are spot on torque wise.
