5/8-11 x 1-1/2인치 소켓 캡 나사 | 버튼 헤드 육각 소켓 드라이브 | 풀 나사산 | 합금강 아연 도금 (50 / 팩)

I needed heavy-duty fasteners for a custom jig I've been building, and these button heads threaded smoothly into the tapped holes without binding. The hex socket drive made them easy to torque down precisely—great for tooling applications.

The zinc plating is holding up nicely on my jigs after a week of heavy shop use, and the button head profile clears tight spots where a standard cap screw would snag. Every one of the fifty threads cut cleanly without any binding. These are exactly what I needed for the tooling rack I'm rebuilding.

The hex socket drive grabbed perfectly on my torque wrench, and the zinc plating handled the slight moisture in my shop without a hint of rust over the last month. These are solidly built for the price, and the 50-count pack means I've got plenty left for future tooling projects.
