براغي رأس مقبس HOLO-KROME 73168 5/8-18 × 4" | محرك مقبس سداسي | فولاذ سبائكي مؤكسد أسود حراري (25 / عبوة)

I needed some heavy-duty bolts for a drill press jig, and the black oxide finish on these has a nice, non-glare look that holds up well in my shop. The 5/8-18 threads engaged smoothly into the tapped holes without any binding.

These bolts threaded in cleanly and the black oxide finish looks great on my press fixture. The 4-inch length was perfect for clamping a thick stack of plates together.

The black oxide finish is perfect for my precision assemblies and these bolts seat really well with a hex socket drive. The 5/8-18 threads were cleanly cut and fit exactly as needed on my tooling fixture. A solid batch of screws for the price.
