1/4-20 x 5/8" 기계용 나사 | 버튼 헤드 육각 소켓 드라이브 | 18/8 스테인리스 스틸 (100개/팩)

Finally, a machine screw that doesn't strip when you're in a tight spot—the button head sits flush and doesn't snag on my panels like the pan heads always did. The 18/8 stainless finish seems like it'll hold up way better than the zinc-coated ones I've used before.

The hex socket drive made these so easy to torque down in tight spots without stripping, and the 18/8 stainless finish has held up perfectly in my damp garage. I used them to mount a metal enclosure and all 100 came out of the package clean, no burrs or duds.

I've been using these to mount brackets inside electrical enclosures, and the hex socket drive makes them much easier to tighten in tight spots than a slotted screw. The 18/8 stainless seems like it'll resist rust well in our damp workshop.
