Good but tight

Screws are good quality but some nuts were hard to thread. Still usable for most projects.

Excellent Kit

Very comprehensive set for my 3D printer repairs. The organization box makes finding the right size easy.

Case cracked

Hardware is fine but the plastic box arrived with a crack. Functionality is not affected though.

Great Value
