براغي رأس أسطوانية M24-3 × 60 مم | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 مع أكسيد أسود حراري (10 / عبوة)

I needed some high-strength fasteners for a precision assembly, and these M24-3 x 60mm socket cap screws fit perfectly. The hex socket drive made installation straightforward, and the black oxide finish looks great. They feel solid and well-made.

Installed these in a custom jig for a heavy-duty press; the black oxide finish held up perfectly against a few light oil sprays. The hex socket didn't strip even with a high-torque driver, which is exactly what I needed for precision work.

These bolts threaded smoothly into my jig fixture without any binding, and the 12.9 grade gives me confidence they'll handle the clamping force. The black oxide finish looks clean and professional against the steel.
