Shoulder Eye Bolt, M10 304 Stainless Steel Eye Bolts 3/8"x1.18" Eye Bolts Heavy Duty Screw Bolt with Washer and Nuts Set Muti-Function for Indoor Outdoor, 10mm x 30mm, 4 Pack

I bought these to use as anchor points to attach ratchet straps on a Harbor Freight utility trailer. These eyelets seem strong an will built and the studs were the perfect size for the factory holes where the trailer stake pockets were.

My application for this is a bit hillbilly. These are quite heavy duty and will work very well for the few hundred pounds or so it will be subjected to.

I was struggling to find hangar eye bolts to fit my Chauver 4bar 64. The only things I found were at Sweetwater and other music stores. Cost felt extremely high. I went to Ace hardware and Lowes to find they only carry these items in standard sizes. No metrics! I figured I'd try Amazon because they are good with returns if they didn't work. They fir my lights perfect. Very solid pieces. The attached nut helps to align the eye hole where you want it. I believe these are the same 10mm threads that will fly your PA speakers. Not certain but I know I just saved over half my money buying these off Amazon. They aren't black like the ones I saw at the music stores. That's fine with me for the savings.

High Quality eye bolts for a very reasonable price.

Used to add tie downs for my boat trailer. Worked great!
