good man. See if you can get media creds to go to the Optima Batteries Track Day competition thingy. Basically they take 50 of the sweetest, highest horsepower cars at SEMA every year and go out to the desert to some track i forget the name.

It'd be pretty much the coolest thing ever done. BTW so jealous you're going to SEMA. any open spots cause i'm not going to Hammers??? So much AWESOME. I expect cell phone pics of AMURICAN MUSCLE.

[HeavyMetal]

SEMA is the 1st-4th

I will be at the 5th.

[Zullock Holmes]

when's SEMA?? don't forget November 5th, be there or be ghey.

[HeavyMetal]

thanks nig

this will be a lot easier when i figure out what winch im getting and when its actually here...def ideally am gonna mount it base forward if i can. gotta wait til after SEMA

[Zullock Holmes]

we use 3/8's ones on our skidplates and they're pretty legit. I'd be willing to say 8-10 would work as long as the fairlead was at the "base" of the winch. Pulling direction will make a huge difference.

lemme look.

pictures were just for reference maru......


Do some snooping, Fastenal, Penn Manufacturing, etc. I'll check the Grainger catalog for ya.

If you come across some hardened ones, let me know because the only ones I've ever seen where made out of steel so soft they may as well have been aluminum.

anyone have torque specs or shear strength for dome light bolts?

[ninetysix-ex-jay]

God, just buy them....





Pictures for ease.

yeah because thats not a #10 or anything. Those work well holding up dome lights maybe

[HeavyMetal]

i know what the fawkin product looks like............

you got a link to the proper rated stuff?

If your wanted to use cap screws it might be a better idea to counter bore them instead of counter sink because the taper will cut into the recess where the allen bit goes.

[Buffalo Phil]

I'm sure Phil can taper, I dont remember if his shop had the attachment or not

We have a taper attachment on the smaller machine.

Also, if you're worried about strength, the nuts on the bottom of my bumper holding the winch down are welded to the bumper. Could also do a few spots for extra reinforcement.

[Zullock Holmes]

Make a subframe behind the face of the bumper so you can use the required hardware, make a cover plate that sits flush and countersink hardware into that so that the face of the bumper is smooth. you would need another inch of space to make something like that work, but it wouldnt be too hard to do.

This is also good, because when you counter sink you get rid of material, so im not sure how that effects strength.

That's the way i'd do it.

if there is a large shear stress (force applied perpendicularly to the body of the fastener) on the countersunk fasteners then yes they are weaker than using standard bolt.

As long as the majority of the forces these bolts will see are normal stresses (compression/tension) then they will be fine. In this case, the surface area actually increases when countersinking.

As long as you can find grade 8 stuff and you put the fairlead on the mounting plate itself so that the forces are applied properly when you use the winch, i see no issue with it.

[HeavyMetal]

good to know, ive never messed much with that stuff
