براغي رأس سداسي M20-1.5 × 160 مم | فولاد فئة 10.9 غير مطلي | ملولبة جزئيًا (10/عبوة)

Used these to bolt down a heavy base plate on our press, and the partial threading made alignment way easier than fighting a fully threaded rod. Class 10.9 held up through a full day of vibration without a hint of loosening. Exactly what I needed for a stubborn retrofit job.

The partially threaded design made aligning these in my equipment frame so much easier than fully threaded bolts. The 10.9 steel feels rock solid, and the hex head seated perfectly with a standard socket.

The hex head on these M20 bolts grabbed my socket perfectly, no slipping at all during assembly. The partially threaded design saved me time aligning the frame before tightening everything down. Solid 10.9 steel that feels much tougher than the grade 5 stuff I used before.
