HOLO-KROME 76360 براغي رأس أسطواني M12-1.75 X 25mm | محرك سداسي داخلي | فولاذ سبائكي مؤكسد أسود حراريًا (100 / عبوة)

Used these on a jig fixture at work and the M12-1.75 threads engaged perfectly with no binding. The hex socket drive made installation quick with an Allen key.

The thermal black oxide coating on these screws held up perfectly during my jig assembly—no galling at all. They threaded smoothly into tapped holes without binding, which is exactly what I needed for a precision fixture. A solid batch for anyone doing machinery work.

I needed a reliable batch of socket cap screws for some jig building, and these M12-1.75 x 25mm pieces came with a uniform, consistent thread quality. The thermal black oxide finish feels durable and gave them a clean look right out of the package.
