براغي رأس أسطوانية M20-2.5 × 70 مم | محرك سداسي منخفض الرأس | خيط جزئي | فولاذ سبائكي فئة 8.8 (60/عبوة)

Got these for a fixture I was building, and the low head profile saved me clearance space I thought I'd have to redesign for. The hex socket drive bit cleanly every time without stripping.

The partial threading made aligning these in my fixture much easier than fully threaded bolts. They seated perfectly in my jig setup without any binding.

The hex socket drive let me torque them precisely in tight spots where a regular wrench wouldn't fit, and the partially threaded length grabbed perfectly through my fixture plate. Class 8.8 alloy steel feels robust enough for the jig I'm building.
