HOLO-KROME 73032 #8-36 X 3/4" 內六角螺絲 | 六角驅動 | 合金鋼熱處理黑色氧化 (100個/包)

The hex socket drive gripped perfectly on my wrench without any rounding, and these 3/4" screws fit snugly into my jig fixture. I've already used a dozen on a precision assembly and they hold tight without stripping.

The black oxide finish on these #8-36 screws holds up perfectly in my jig setup, no rust after weeks of use. The hex drive bites cleanly every time, making assembly much smoother than I expected.

The thermal black oxide finish on these screws gives them a nice, consistent look, and they threaded smoothly into my tooling jig without any binding. I've used cheaper fasteners that would strip out, but these held torque perfectly for a small fixture assembly.
