براغي رأس كبس M4-0.7 × 55 مم | محرك سداسي | خيط جزئي | فولاذ مقاوم للصدأ 18/8 (300/عبوة)

Used a handful of these for a jig I was building, and the 55mm length was exactly what I needed. The hex socket drove smoothly without any cam-out, and the stainless finish looks clean.

The hex socket drive grips my Allen key perfectly without any stripping, even after tightening them into my jig setup and taking them back out a few times. The 18/8 stainless finish looks clean on the machinery too. These are exactly the right length for my precision assemblies.

The partial threading on these 55mm screws made them perfect for the jig I was building, and the stainless steel feels solid. A full box of 300 gives me plenty for future projects.
