Eva I. ★★★★★

Installed these in a wooden shelf to replace some rusty steel ones—the brass finish really pops against the dark stain. They threaded smoothly into the existing holes and hold the shelf brackets securely without stripping.

Nicholas J. ★★★★★

I needed brass screws for a small electronics project and these fit the bill perfectly—the flat heads sit flush against the surface, and the Phillips drive made installation straightforward. Good corrosion resistance is a bonus for my outdoor application.

Alexander I. ★★★★★

These brass screws look even better in person than I expected for a project where I wanted a warm, decorative touch without any magnetic interference. The Phillips drive bit seated perfectly on every one of the hundred screws I used, and the flat heads sat flush in the predrilled holes.
