Good assortment
Most sizes are very useful for general repairs. I wish there were more M8 nuts included, but overall satisfied.

Excellent quality for the price
These nuts fit perfectly on my metric bolts. The galvanization looks solid and the case keeps everything organized.

Great for workshop
Having all these sizes in one box saves so much time. The washers are a nice bonus.

Strong and reliable
Used these for a structural project. Grade 8.8 holds up well under torque without stripping.

Solid hardware kit
Good value. The plastic case latch could be stronger, but the contents are high quality.
