براغي رأس كبس M20-2.5 × 30 مم | محرك سداسي | ملولب بالكامل | فولاذ سبائك فئة 12.9 مطلي بالزنك (25 / عبوة)

I had to replace some worn fasteners on a heavy-duty fixture, and these M20-2.5 x 30mm screws fit perfectly. The hex socket drive made installation quick with no cam-out issues, and the zinc plating seems like it will resist rust well.

The hex socket drive on these screws gave me a much better grip than standard bolts when assembling a precision tool. They threaded smoothly into tapped holes without any binding, and the zinc plating looks clean and durable.

Installed these in a jig fixture and the 12.9 grade steel held up perfectly under heavy clamping pressure. The zinc plating gives them a nice, uniform finish that resists minor rusting.
