براغي رأس أسطوانية M16-2 × 90 مم | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي فئة 8.8 مطلي بالزنك (25 / عبوة)

The hex socket drive grips my Allen key perfectly with zero wobble, and the class 8.8 alloy steel feels genuinely sturdy for jig building. Threads ran clean through my fixture plate without any binding, so I’ve already ordered another pack.

The zinc plating is flawless across all 25 pieces, no burrs or rough edges anywhere on the threads. These seated perfectly into my tooling fixture and the hex socket drive gave a solid grip without any stripping.

Was pleasantly surprised by the fit and finish on these screws — the hex socket drive engages perfectly with my Allen keys. The zinc plating looks clean and even, which matters for the tooling setup I'm working on.
