The bolts are very well made. They have a nice smooth finish and appear to be threaded correctly. I have them exposed to weather and no problems yet. I would recommend them.

Not all stainless steel is equally good. This product, however, is really superior. SR

I was very satisfied with the stainless steel bolts, they worked perfectly for bolting new plastics on ATV. I would definitely buy from this company again. Very prompt on shipping and customer service.

The length was exactly what i needed for my project. The finish is bright, but not a mirror polish. they look great on the bench I refinished..

These are great for making your license plate tamper-proof! These match with my simple stainless steel plate frames. Pair them with some Nylok Stainless nuts and you're good to go!

I am using these for a Prinsu roofrack on a Toyota Land Cruiser 80 series. You will need to use a washer if you are bolting some items to it because the square part of the bolt will protrude a little. Other than that they look good.

These bolts are advertised by the Chineses company to be top quality stainless steel. They react to a magnet. Generally, both facts cannot coexist. Used them on rolling outdoor plant stand. We'll see if they rust over time. So far (one month) so good.
