Pros and cons

Pros

The five short lengths offer options for small-scale assemblies while keeping to one thread size.
A 530-piece count provides multiple fasteners for ongoing small repair or project use.
The listing claims a compartmented storage case for sorting the different sizes.

Cons

The assortment is limited to M1.6 screws, so it will not cover projects needing other thread diameters.

Frequently asked questions

What screw sizes are listed?

The listing gives M1.6 screws in 4, 5, 6, 8 and 10 mm lengths. It says length is measured from under the head.

Does the assortment include nuts?

The feature text states that it includes 30 M1.6 hex nuts. Check the selected listing if that quantity is important, since the package details are not given as a separate explicit box inventory.

Are these screws suitable for any M1.6 project?

Not necessarily. Check the required length, head style and Phillips drive, as well as the matching thread, before choosing them.
