    • Very well made. Stainless steel. Great value.

    • Nice stainless bolts/washers/nuts
Size: 5/16-18 x 3/4" (10 Sets)
I bought these to replace the steel bolts on my snow blower during a rebuild. The finish of the hardware was good, and the thread on the bolt/nut was smooth without any roughness or burrs. I did not use the nuts in my application as I needed nylock nuts, but am happy with the purchase of this set.

    • Works Great
Size: 1/4-20 x 2" (10 Sets)
Probably one of the most popular sizes for woodworking/audio/video/still photography work. I make my own brackets and jigs and use the quarter by 20 bolts, knobs and nuts. So versatile!!

    • my mistake, I bought the wrong size...
Size: 3/8-16 x 2" (8 Sets)
I opened the box and, oops; closed it back up and sent it back, immediately ordered 2 more boxes of the correct size. This is very nice looking hardware. It took forever to get here, both times; I am still waiting for the refund on the return, 29 days so far...

    • good price for 10 sets.
Size: 1/4-20 x 4" (10 Sets)
I needed 10 bolts and these would have cost double or more at the hardware store. Saved gas not driving there.
