Good Value for Money

Great price for the quantity. One or two had slightly rough heads but nothing affecting function. Would buy again.

Perfect for CNC Projects

These screws fit perfectly into my aluminum extrusions. The steel quality seems solid and didn't strip easily during assembly.

Missing Sizes in Kit

The box said assorted but I only received M4 and M5. Contacted support though and they resolved it quickly.

Reliable Fasteners

Bought these for repairing appliances. Stainless steel prevents rust which is key for me in humid environments.
