Well made and sturdy
Work great as pick point hooks on camera for the kong clamp with the EZ rig.

Super high quality hardware
This is a great value for hard to find stainless steel hardware. I always appreciate the price and verity of specialized hardware on Amazon. For decades, the only real go-to has been AceHard. for hardware like this ( if they would even have something like it ) But now, if you know what you need, Amazon has the biggest selection at affordable prices. As such, my new go-to when I need something odd or different. ... show more

Real 3/8" thread, not metric
I used these to finish off my bedrail project in my Ford Maverick. I could not find these in any local store. I wanted lifting eyes, not eye bolts. And I also wanted stainless steel so they would not rust when exposed to the elements. These are real 3/8" not metric. Some product ads say they are the same thing. They are not. They worked perfectly and they are super strong for tying down things in the truck bed. ... show more

Great quality
Used these on a trailer as a boat hold down, the quality is great and they fit as advertised. Can't go wrong for the price.

Appear to be Well Made
I used them to make a tire swing. They were rated way above my use so I can't judge their strength. I drilled 4 holes in the tire and put 4 eyebolts so no test of strength here. They appeared to be well made and no some cheap eyebolt. I used eyebolt in my 40 years as a refinery Machinist and to me they looked trust worthy and well forged or casted. ... show more
