1/4-20 X 5/8" 소켓 캡 나사 | 육각 소켓 드라이브 | 미국산 | 풀 스레드 | 18/8 스테인리스 스틸 (100 / 팩)

These are my new go-to for jigs and fixtures — the hex socket drive grips perfectly with a ball-end Allen key, and the 18/8 stainless threads seat without binding. All 100 came sorted and unmarred in the package, which I appreciate when I'm mid-project.

The threads cut clean into my aluminum fixture with zero binding, and the hex socket drive grabbed perfectly with my Allen key on the first try. I’ve used cheaper stainless bolts before that galled, but these 18/8 ones held torque without a hint of that.

Had to replace some hardware on a jig I use daily, and the hex socket drive made installation in tight spots much easier. The 18/8 stainless finish looks clean and feels solid, no burrs unlike cheap imports. For the price per pack, these are a great value.
