Good quality, great variety

The plastic is sturdy and doesn't strip easily when tightened. I took off one star because the M2 nuts were a bit tight on the threads, but overall a very useful kit.

Perfect for electronics projects

These nylon screws are exactly what I needed for my 3D printer upgrades. They are non-conductive which is crucial for the wiring areas, and the assortment covers all the sizes I frequently use.

Essential for corrosion-prone areas

I used these for a bathroom fixture repair where metal screws would eventually rust. The nylon holds up well against moisture and the countersunk head sits flush perfectly.

Great value assortment

Having the washers and nuts included saves so much time. The organization in the box could be better, but the quantity and quality of the fasteners make up for it.

Exactly as described

Fast shipping and the product matches the description perfectly. The cross-head drive works well with standard screwdrivers without slipping.

Solid plastic fasteners

Used these for mounting sensors on a drone. They are lightweight and strong enough for the application. Just be careful not to overtighten as with any plastic screw.

5 FAQ

Q: What is the maximum torque recommended for the M4 size?

A: For M4 nylon screws, we recommend a maximum tightening torque of approximately 1.2 to 1.5 Nm to prevent stripping the threads or breaking the head.

Q: Are these screws suitable for outdoor use in direct sunlight?

A: While nylon has good weather resistance, prolonged exposure to direct UV sunlight can degrade the material over time. For permanent outdoor installations, we recommend using UV-stabilized variants or protective coating.

Q: Can these withstand exposure to common household cleaning chemicals?

A: Nylon PA66 generally resists most weak acids, alkalis, and solvents found in household cleaners. However, we advise avoiding strong oxidizing agents.

Q: Is the white color consistent across all sizes?

A: Yes, all screws, nuts, and washers in this assortment are made from the same natural white nylon material, ensuring a consistent appearance.

Q: Do these come with a storage case?

A: Yes, the assortment comes in a compartmentalized plastic organizer box to help keep the different sizes and components separated.
