Harness eye-bolts

I'm going to run clip-in harnesses on my truck, and I know the normal thing to do is to cut the threads off the eye-bolts that come with the harnesses, and weld them to the cage. My question is, because I not only need to tig on 12 for the harnesses, but want to run them throughout the rear of the truck as tie-down points, and I'm not too into the idea of cutting the threads off and cleaning the plating off somewhere around 30 of the little things. anybody know where I can get some with no zinc plating? McMaster-Carr has stainless, but I'm not sure stainless is the right way to go. I'm also not sure what size they technically are, I know the threads are 7/16s fine thread, and the eye is roughly 1/4", but not 100% sure how they're sized.

I keep several lengths of those bolts "in stock"....I live in Burbank just a couple of miles from Deist safety so I'll pick up them up as needed always buying extras...We love these things and use the heck out of them for much more then seat belts...

These are forged rating for something like 5,000 lbs....Hard to find other eye bolts that highly rated in a comparable size. I would stick to the seat belt safety bolts for the harness's, for simple tie-down points I'm sure the SS ones found in M/Carr would work fine...

We use Muriatic acid(for cleaning pools, concrete) to chemically strip the cad plating off any fasteners we need to weld...Works AWESOME...just be very carful of fumes!

This is how I know to clean the plating off. Just do it outside and don't breath the fumes, you'll know why if you do. Use a plastic container and dip the eyebolts. Using gloves (for use w/ acid) or a tool to remove eyebolts from acid and rinse w/ water and dry.

How long do you need to keep it in the acid (I have never tried it)? Will it only affect the coating, or will it damage the bolt if you leave it in too long?

I leave them in for about a minute or so...When the acid meets the plating there is some bad gassing, so we put the small plastic container outside by a water hose...after that I'll then fill the container with water to further neutralize the acid and then wash off the parts.

This works great when trying to weld Gr8 nuts to a plate....

I have a couple gallons of muriatic acid in the garage, didn't even think of it. I'll run the normal Crow eyes for the belts and whatever's cheap and decent to tie down the tool-bags.

Thanks.

Marshalls hardware in San Diego has those type eyebolts and they're not coated. Kind of spency though if you don't need that kind of strength.

Dont use clip-in points for the shoulder harnesses. They should be bolt in or wrap around and locked with double sliders.

Is this a rule requirement or a preference?

Curious why you say that? Everybody I've ever talked to, including myself, prefers clips in all locations for ease of removal while prepping, only downside I can see is that being my DD the unused harnesses may clatter a little.

maxyedor, not to side track your thread, muriatic acid can be some ugly stuff if not handled appropriately. Make sure you read up on acids first and proper neutralizing before jumping into it. Just because you can buy it in the grocery store doesn't mean it is harmless. Also...and more importantly, just because some have gotten away with improper handling doesn't mean it is the acceptable method, FWIW.

Absolutly!....I didn't go into detail, but I posted that we did this outside(fumes) and next to a garden hose(safety) just because this stuff needs to be handled smartly...you don't want this stuff in your eyes!..and the fumes will F-U-UP...

If the belts come supplied with clip-ins for the shoulder harnesses and the instructions show using the clip-ins on the shoulder harnesses then there is no reason that they can't be run that way. All safety harnesses are tested and all installation instructions reviewed. Unless you get some made in China crap of coarse..

If you have any doubts about installation it would be best to contact the harness manufacture.


And also agree with the warnings about handling the muriatic acid. Be careful this stuff is no joke! You get it your eyes you will be lucky to see correctly again, I don't even want to find out.. Breath in the fumes and you'll live if its not to much --> (say using in enclosed area:eek:) but you may wish you were dead..

Just use a small amount, just enough to get the job done. Stay outside and by water and all will be good. Safety glasses can never hurt:)..

Done and done. I use Muriatic acid fairly often for cleaning metal, just somehow didn't think of it for this. Always outside, acid safe gloves, goggle and a mask.


Still curious to know the reasons not to use clip-ins. Double D rings are a whole other deal, and I agree they should be used, although I always thought it was weird that harnesses don't come standard with them. I can almost see the argument for running wrap-around over any other method of attachment, but I figure almost anything I do is better than factory riv-nut in 20ga sheet-metal which passes crash tests just fine.

I agree with all and say that any supplied mounting method will work effectively.

I was just told and see the logic that wrap around has a nearly zero percent chance of failure and if your car is set up for that (with a well placed tube), than why not.

Everything I order from my safety specialist is made custom with specifications that I desire.

Prep is the main reason I like the clips. I have zero doubt that I'll be dead long before the eyelets rip off the tube. With wrap-arounds I'd have to weave all the shoulder and lap belts through all the double D-rings while wedged in the truck sideways, rather do it sitting on my couch then spend 5 minutes clipping them all in and installing the cotter-pins.

Preference. Wraps are not recommended.

Clip-ins are no different than bolt-in. You still have to use double d-rings. Just make sure you cotter key or safety wire each clip to keep the gate closed
