براغي رأس سداسية M16-2 X 50mm | فئة 8.8 صلب عادي | ملولبة بالكامل (50 / عبوة)

Used these for mounting a heavy steel bracket on a workbench, and the full threading gave me plenty of grip for a secure hold. The Class 8.8 steel feels solid and hasn't stripped at all during tightening.

I've been using these for a few weeks on some assembly line jigs, and the hex head makes getting a socket in tight spots a lot easier than a standard bolt. The threads bit cleanly into the pre-tapped holes with no binding. Solid buy for the price.

Installed these to secure a heavy conveyor frame and the class 8.8 steel held the torque perfectly without stripping. The fully threaded design let me adjust the grip depth exactly where needed.
