HOLO-KROME 72308 3/4-10 X 2" 內六角螺絲 | 六角驅動 | 合金鋼黑色熱處理氧化 (25 / 包)

The black oxide finish on these socket cap screws really grips the hex key well without slipping, and the threads cut cleanly into my jig plate. I'm impressed with how precisely they fit the tapped holes—no wobble at all in my tooling setup. Definitely the quality I expect for machinery work.

I needed some heavy-duty fasteners for a tooling jig, and these 3/4-10 socket cap screws fit perfectly. The hex drive made installation smooth, and the thermal black oxide gave them a nice, durable look. They feel solid and well-made for the price.

The black oxide finish on these screws looks sharp and held up fine while I was tightening them into a steel jig. The hex socket drive seated the Allen wrench snugly, no stripping or wobble even at full torque. Fits exactly like the 3/4-10 spec I needed.
