براغي ذات رأس أسطواني بمقبس سداسي HOLO-KROME 76096 M4-0.7 X 45mm | محرك سداسي | فولاذ سبائكي مؤكسد أسود حراريًا (100 / عبوة)

Perfect fit for my jig build—the black oxide finish cut way down on rust worry in my damp shop. Drove them in cleanly with a hex key, no stripping at all.

I needed longer screws for a jig I was building, and these 45mm lengths fit the bill perfectly. The hex drive seated smoothly and felt solid under torque, no stripping issues at all.

The black oxide finish is really uniform across all 100 pieces, and the hex drive bites cleanly without stripping. I’ve torqued these down into steel and aluminum alike, and they hold like they should. For the price per screw, it’s hard to beat this box for precision assembly work.
