圓頭螺絲 1-72 x 3/8" 25入

These little brass screws are a lifesaver for my model train builds—the round heads sit flush and the threads are cut cleanly on all 25 in the pack. I've already ordered a second set.

For tiny brass screws, these are beautifully machined—the round heads fit my mini screwdriver perfectly and all 25 came out of the package with zero burrs. I've already used half on a small clock repair and they've held up great.

Finally, a tiny brass screw that actually fits the model train couplers I’m restoring — the 1-72 threads are spot on and the round heads seat nicely. A full 25 in the pack means I’ve got spares for the next project, and they’re machined clean without any burrs.
