I often see threads about how to lift machines. Here is the cheapest source I know of for decent quality eyebolts and similar rigging. Cheaper then I paid on ebay.
For some reason they also sell pricey barbecues?

Thank you. It's great to have good sources.
Having bought a lot of Certified lifting hardware at much higher prices, I would be a little dubious of the quality here. The website does have some good general information on rigging. Maybe I missed it but I could not find any hardware grade or certification listings.
Beware, there is a lot of counterfeit hardware being sold on the internet.
I very strenuously agree with Bruce's comments. I am a construction safety specialist. Any "qualified rigger" (OSHA term) can verify the counterfeit hardware that is available and the catastrophic results from using components that are almost undetectable as counterfeit. The only way we buy rigging equipment is through a specialist supplier who is an authorized dealer of American made hardware. Hook, shackle and other failures are widely documented. Even with the certified hardware, the proper use and application of the components is vital. Even small picks can be deadly!Quote:

I've seen certified equipment failures when not used properly or overloaded. Ever watch a 50 ton shackle snap in half when a 220 ton lifting capacity crane is used to pull on it with 2.5" cable slings? They fly pretty well It works the same for a1/2" cable sling or web sling if not used properly or inferiority products are used. Safety at all times should on your mind when using this type of equipment
I did find these comments on their websiteQuote:

As a protective coating, shackles are hot dip galvanized. Manufacturer certificates can be provided on request.
OP Here: I agree that the quality could be doubtful but I think you can tell the real bad ones will look and feel bad in the hand. I also would never get close to the load limits. I figure for my use each eyebolt is rated for 100-400% of the load and I am using four or more so there is a good safety factor. For that lathe lift the one eybolt was only rated around 250% over load so not so much of a safety factor as I like.

im going to lift a few shapers up five feet shortly. The chain goes to four places rated for 6,600 lbs so 26,400 lbs rating total. 1/2" grade eight bolts rating not in front of me gaggle of washers on each side with the bolt passing through the 3/8 grade 70 transport truck chain. I think the same stuff about quality of lifting stuff but dont sweat it at this point there is enough overkill it my stuff im responsible if it was others stuff then id have certified stuff.
One day I was lifting lifting a machine with a half ton block and tackle, im looking then notice one link was not welded during manufacture. So now I end up checking every link on every chain.
I do not know what certified means anymore. you can buy stuff made in china and they will give you any certificate you want. many there will also label them with any brand you want as well.
I looked at 1-2 inch micrometers at Harbor Fright. they all included standards and all the standards were exactly one inch long! Any real one s would be off at least 0.001" either way and be marked that way.

I am surprised certified lifting hardware can be hot dipped or painted. Ladders should never be painted for inspection reasons. The good lifting rings I bought are zinc chromated? but lightly so any fractures/flaws will show through.
