HOLO-KROME 73114 3/8-24 X 2" 소켓 캡 나사 | 육각 소켓 드라이브 | 합금강 열처리 블랙 옥사이드 (50 / 팩)

These threads cut like butter with the 3/8-24 pitch, and the black oxide finish leaves no residue on my jig plates. Fifty in the box is plenty for a few months of tooling work, and every one I’ve pulled from the package has been spotless.

I needed some high-strength fasteners for a jig I was building, and these 3/8-24 x 2" socket cap screws fit the bill perfectly. The hex socket drive made installation a breeze, and the black oxide finish is a nice bonus for corrosion resistance.

The black oxide finish on these screws lets them slide into tapped holes much easier than the plain steel ones I used before. They're holding up great under the constant clamping force on my milling machine fixture.
