براغي رأس سوكيت M6-1 X 25mm | رأس مسطح بمحرك سوكيت سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 10.9 بأكسيد أسود حراري (400 / عبوة)

The black oxide finish on these screws lets them slide into tight spots without galling, and the full threading gives great grip in aluminum jig plates. I've already used about a hundred on a custom machine base, and every one seated cleanly with the hex key.

Used a full box assembling custom jig plates and every single screw threaded cleanly without binding. For the price of a fast-food lunch per fastener you get genuine Class 10.9 strength that holds up to serious torque.

The black oxide finish really resists wear—I’ve been using these in a jig for a month without any rust. The hex socket drives smoothly with no cam-out, and having 400 in the box should last me through several projects.
