Quality Parts at a Good Price
Very impressed with this hardware. Used these to fasten together some end-of-driveway curb ramps also bought on Amazon. These parts seemed well made and were all in spec.

Withstands torque without presenting problems for me.
Good quality and was perfectly suited for the task.

Nice quality!
Very high quality with a nut, washer and lock washer. I bolted down a vise on my workbench and it's nice and solid. Highly recommend if you're bolting equipment down such as a drill press, table saw, or even using as a bolt for clamps. Very sturdy and high quality

Useful
Worked as they should.

Misleading on ad
Appear to be good quality Ad is misleading. Shows six bolts but you only receive 4. So you need to read ad very carefully

Quality Built
Great bolt even though the price is on the higher size. But you do receive what you paid for.

Smooth
Served the purpose.

Just what I needed
The box stores don't stock all sizes of stainless steel hardware, and it takes forever to arrive if I have to order it (10+ days). These arrived next day and are exactly what I needed.
