Bolt on slider torque recommendations?

Bolting on some demello off road sliders tomorrow. Anyone have suggestions on ft. Lb torque specs when tightening them down? I'm guessing somewhere around 50 ft lb based on other factory specs, but that's just a guess. Unfortunately the instructions don't have any recommendations. Thanks for the help!

 

look up a bolt size torque chart and shoot for the middle of each range.

 

AllPro's bolt on sliders spec 44ft/lbs.

 

Check bolt heads for Grade # as well.

 

Thanks guys! Sliders installed. Not easy to do by yourself in a one car garage with no jacks....but it is possible. Would've gone much quicker if I read the instructions more carefully!

 

Looks good!

Nicely done! That must have been a challenge to do solo with no jacks.

 

1/2 hardware is usually around 50lbs
3/8 usually 30-35lbs

 

congrats!

 

Super ghetto, but I literally found a box the right height and made due using that to prop them up while securing enough of the bolts so they could hang.

Tuff to see in the pic, but there ya go. Where there's a will there's a way.

 

Are these Demello's round sliders? Did drill your frame or just bolt on? How do you like these sliders? Are they angled up? Does it look like you give up a little bit of clearance from it sticking down?

 

Lol I didn't know there were torque specs. I have SOS sliders, but I'm a solid 100 ft lbs over allpros recommendation haha.

 

I do all our installs with my 1/4" DeWalt Impact Driver, 1400 in-lbs (116 ft-lbs) with no issues. All our hardware is grade 8, 3/8-16 and 1/2-13.

3/8" grade 8 hardware is 45 ft-lbs
1/2" grade 8 hardware is 110 ft-lbs

That's according to Engineers Toolbox but IMO that's far too low for what these parts weigh and their intended use.

Looks like you got them on there so this was more of a informative post for others to reference.

 

Haha so true.

 

1/2 grade 8 can go way higher.
50lbs is the spec for grade 5.

Probably remember my issue with the RCI ones so I bought all grade 8, and with all the stuff I bought got the manufacturer spec on it. for 1/2-13 grade 8 yellow was 70-80lbs.

 

Reference Chart

 

over and under torquing biggest issues can be either damaging the threads and it not staying tight.
An over tightened bolt will loosen easier than a proper torqued one.

Too little of torque and it will loosen as well. So ya.
I've said before I guess it also depends. Torque spec is a major aspect for me at work given liability etc.
faulty switch gear can cost millions in damages and possibly lives. Especially when you get into high voltage switches.
Improper torque spec and you can get hot spots and arcing.

 

Very, very true. Some things, torque specs are EXTREMELY critical but bolting sliders to a chassis is not one of them lol.
