براغي M10-1.5 × 180mm ذات غطاء مقبس | محرك مقبس سداسي | ملولبة جزئيًا | فولاذ سبيكة فئة 12.9 مطلي بالزنك (25/عبوة)

Used a few of these to reinforce a heavy-duty press frame, and the 12.9 alloy steel held up without any flex. The hex socket drive made installation straightforward with a standard Allen key.

I needed extra-long bolts for a jig I'm building, and the Class 12.9 hardness on these feels rock solid compared to standard hardware. The hex socket drive made installation with my Allen key straightforward even in a tight spot.

The partial threading on these 180mm screws made all the difference for my jig setup—held tight without any wobble. They threaded smoothly into tapped holes with no binding, and the hex drive seated perfectly every time.
