Good quality, fast shipping

The screws arrived quickly and were well-packaged. The finish is smooth and consistent. I deducted one star only because I wished there were more M4 sizes in the mixed pack.

Great for electronics housing

I use these for securing brass plates on custom electronic enclosures. They look professional and the flat head sits flush as expected.

Solid hardware

Very sturdy screws. The threading is clean and they tighten smoothly. Good value for the price compared to local hardware stores.

Exactly as described

No complaints here. The M6 size fits my brake band assembly perfectly. Will definitely order again when I run out.

Perfect fit for my restoration project

These brass screws are exactly what I needed for restoring an old radio. The H62 brass quality is excellent, and the cross recess holds the screwdriver well without stripping.

Excellent for marine applications

Using these on a small boat fixture. Brass is naturally resistant to corrosion, and these GB819 standards fit perfectly into the pre-drilled countersunk holes.

5 FAQ

Q: Are these screws suitable for outdoor use?

A: Yes, H62 brass offers good corrosion resistance, making these screws suitable for many outdoor applications, though extreme marine environments may require additional coating.

Q: Do these come with matching nuts?

A: No, this listing is for the countersunk machine screws only. Nuts are not required for countersunk applications where the screw threads directly into a tapped hole.

Q: What is the thread pitch for the M5 size?

A: The M5 screws follow the standard GB819 metric coarse thread pitch, which is 0.8mm.

Q: Can I buy just the M8 size separately?

A: Currently, we sell them in mixed packs or bulk boxes of specific sizes. Please check the variant options on the product page for single-size availability.

Q: Is the head diameter standard for M4?

A: Yes, the head diameter conforms to the GB819 standard specifications for M4 countersunk screws, ensuring compatibility with standard tools and holes.
