HOLO-KROME 72104 1/4-20 X 1-1/2" براغي ذات رأس أسطواني | محرك سداسي داخلي | سبائك فولاذية مؤكسدة حرارياً باللون الأسود (100/عبوة)

Picked these up for a small machining fixture I’m building, and the black oxide finish makes them hold up nicely to oil and chips without rusting. The hex drive seated cleanly in my Allen wrench on every single one.

I needed a solid batch for building jigs, and these 1/4-20 x 1-1/2" socket cap screws fit the bill perfectly. The hex socket drive grabs well without stripping, and the black oxide coating seems durable.

The black oxide finish on these screws looks sharp and held up fine during assembly on my jig. They seated cleanly with a hex key, and the 1/4-20 threads engaged smoothly every time, so I'll be ordering another pack when I run low.
