براغي ذات رأس مقبس M16-2 X 100mm | محرك مقبس سداسي | ملولبة جزئياً | فولاذ سبائكي فئة 8.8 أكسيد أسود حراري (25/عبوة)

The black oxide finish on these M16 screws held up perfectly against the oil and grime in my shop, and the hex socket drive made them easy to torque down in tight jig spots. They fit my machinery mounts without any wobble, and the partial threading gave just enough grip for the load.

The partially threaded design grabbed perfectly in my tooling block, and the black oxide finish made them look clean right out of the pack. Fit was snug with a hex key, no wobble at all. Solid little fasteners for the price.

I needed something heavy-duty for a jig I was building, and these 100mm screws with the thermal black oxide finish fit the bill perfectly. The hex socket drive grabbed my Allen key securely without any wobble, and all 25 in the package had consistent threading.
