براغي رأس أسطوانية M20-2.5 × 80 مم | محرك سداسي منخفض الرأس | ملولبة جزئيًا | فولاذ سبائكي فئة 8.8 (50 / عبوة)

Installed these on a jig table I’m building, and the partially threaded shank made alignment much easier than with fully threaded screws. The hex socket drive gripped well without stripping, and the 8.8 alloy steel feels plenty sturdy for heavy tooling use.

These fit perfectly into my jig setup, and the hex drive made tightening them in tight spaces a breeze. The Class 8.8 alloy steel feels plenty tough for the tooling work I do.

Had to swap out some worn bolts on an industrial press, and these held up to the torque without any issues. The partially threaded design was exactly what I needed for that application.
