Fast shipping and great quality

Arrived two days early. Every screw and nut fits perfectly without stripping. The cross heads are deep enough for a good grip with a standard screwdriver.

Excellent organization

The plastic case is sturdy and the compartments are well-sized. No mixing of sizes occurred even after dropping the box accidentally. Highly recommend for hobbyists.

Perfect for my workshop needs

This assortment kit is exactly what I needed. The separation in the box makes it easy to find the right size quickly. The zinc plating looks solid and should prevent rust.

Best purchase for DIY electronics

I use these for mounting components in my custom PC builds. The M3 and M4 sizes are perfect. The round head looks clean and professional once installed.

Good value but mixed quantities

Great price for the amount you get. The quality of the steel is decent for general use. I wish there were slightly more M4 screws as I use those most often, but overall very satisfied.

Solid basic kit

Nothing fancy, just a reliable set of fasteners. The washers are a bit thin but functional. Good to have on hand for emergency repairs around the house.
