براغي رأس أسطوانية M16-2 X 80mm | محرك سداسي داخلي منخفض الرأس | ملولبة جزئياً | فولاذ سبائكي فئة 8.8 (90/عبوة)

The low head design was perfect for the tight clearance we had on our tooling jig—freed up valuable space. All 90 screws threaded smoothly into the tapped holes without any binding or galling. Great value for a specialty fastener like this.

Bought these for a jig build and the low head profile gave me just enough clearance under the fixture plate—that alone saved me a re-design. I’ve used cheaper cap screws before, but these threads seated smoothly without any binding, and the Class 8.8 rating feels solid for the torque I put on them.

The partially threaded design made alignment much easier when I was building a custom jig, and the hex socket drive held up perfectly under high torque.
