Best seller for a reason

Fast shipping and well-organized packaging. Each screw fits its corresponding nut and washer perfectly. No cross-threading issues encountered so far.

Solid value

Good price for the quantity received. The brass is genuine and heavy. Took off one star because the plastic case latch was a bit fragile, but the contents are perfect.

Good variety, one size missing

Great assortment overall. The quality is top-notch and the threads are clean. I wished the set included a few more of the M4 sizes, but otherwise, it's a solid purchase.

Excellent quality brass

These screws are exactly what I needed for my vintage radio restoration. The brass is thick and doesn't strip easily. The inclusion of washers and nuts saved me a trip to the hardware store.

Perfect for decorative projects

The gold tone looks beautiful on my custom wooden jewelry box. The countersunk head sits perfectly flush with the surface. Very satisfied with this set.

Professional grade fasteners

I use these for electrical panel assemblies where non-magnetic properties are required. They work flawlessly. The spring washers provide good tension.

5 FAQ

Q: What is the thread pitch for the M5 screws in this set?

A: The M5 screws in this National Standard set feature a coarse thread pitch of 0.8mm, which is standard for general machinery applications.

Q: Can these be used with aluminum materials without galvanic corrosion?

A: Brass and aluminum are relatively close on the galvanic scale, making them generally compatible for many applications. However, in highly corrosive environments, using an anti-seize compound is recommended.

Q: Does this set include a driver bit?

A: No, this combination set includes only the screws, flat washers, spring washers, and nuts. A Phillips head screwdriver must be purchased separately.

Q: Are these screws suitable for outdoor marine environments?

A: While brass has good corrosion resistance, pure brass is best suited for indoor or dry outdoor applications. For constant saltwater exposure, we recommend stainless steel 316 grades.

Q: Is the box resealable?

A: Yes, the compartmentalized plastic box features a snap-shut lid designed to keep the various sizes organized and prevent spillage after opening.
