HOLO-KROME 64090 براغي رأس مقبس 5/8-11 × 2 بوصة | رأس زر بمحرك مقبس سداسي | سبيكة فولاذ بأكسيد حراري أسود (25 / عبوة)

The black oxide finish on these gave them a nice, uniform look right out of the bag, and the button head profile sits flush enough for tight clearances on my fixture. Threads cut cleanly into 1018 steel without any binding, which is exactly what I need for repeated tear-downs. For the price per piec

Installed these on a custom jig I’m building and the black oxide finish gives them a nice, uniform appearance. The hex drive seated easily without stripping, and the 2" length provided plenty of grip in my steel plate. Solid choice for precision assemblies.

The button head sits flush perfectly in my jig’s counterbore, and the hex drive made installation much easier than a standard bolt. These are holding up great under moderate torque on my shop fixture.
