Good quality but no nuts
The bolts are solid and the galvanization looks even. Just be aware you need to buy nuts separately.

Great for shelving units
Used these to assemble heavy duty warehouse shelves. The square neck prevents spinning which is a huge plus.

Perfect fit
The M8 size fit perfectly into the pre-drilled holes of my furniture kit. Very satisfied.

Solid hardware
Strong bolts for the price. Shipping was fast. One bolt had a slightly stripped thread but the rest were fine.
