Lucy ★★★★★

These partially threaded screws are perfect for the jig I was building; the flat head sits flush and the brass finish looks professional. The hex socket drive made installation straightforward with my Allen wrench.

Owen ★★★★★

I needed brass fasteners that wouldn't corrode in a marine environment, and these partially threaded screws threaded smoothly into my jig without binding. The hex socket drive made tightening them a breeze even in tight spots.

Sofia ★★★★★

The flat head sits perfectly flush in my jig, and the hex socket drive made installation a breeze with no stripping. These brass screws feel sturdy and the partial threading held tight under load. Exactly what I needed for precision assembly work.
