Perfect for furniture

Used these for assembling a bookshelf. The countersunk head sits flush which gives a very clean finish. Highly recommend.

No rust yet

Used outdoors for a month on a garden box. Still clean and no signs of corrosion despite rain. The 304 steel is legit.

Good but strict

Overall good screws. The heads are slightly small for some worn bits, so use a good driver. Otherwise, they hold well.

Excellent quality

Very sharp and the black coating looks premium. Used them for a custom cabinet project and they drove in smoothly without stripping.

5 FAQ

Q: Are these screws rust-proof for outdoor use?

A: They are made of 304 stainless steel which offers high corrosion resistance, making them suitable for most outdoor applications.

Q: Is the black coating durable against scratching?

A: The black oxide treatment is durable, but like any coating, it can scratch under extreme friction during installation.

Q: Do you offer bulk pricing for large orders?

A: Yes, please contact our sales team directly through the store page for bulk pricing options on large quantities.

Q: Can I use these on hardwood without pre-drilling?

A: While they are self-tapping, we recommend pre-drilling for hardwoods to prevent splitting and ensure a flush finish.

Q: What driver bit size is recommended for M4?

A: For M4 screws, a PH2 Phillips bit is typically the best fit for optimal torque and to prevent cam-out.
