براغي رأس سداسية M20-2.5 × 260mm | فولاذ فئة 10.9 عادي | ملولبة جزئيًا (4 / عبوة)

Installed these on a heavy conveyor frame and the hex head took a socket wrench without slipping. The partial threading let me snug the nut tight without binding. Solid 10.9 steel, no stripped threads.

The partially threaded design made these cap screws perfect for securing heavy machinery panels without binding. The 260mm length gave me just enough reach for a thick assembly, and the hex head fit my socket wrench perfectly.

The hex head gave my socket wrench a solid grip, and the partially threaded shank made installation into a steel frame much easier. These bolts held tight without any slippage. Really solid hardware for the price.
