براغي رأس أسطوانية M10-1.5 × 140 مم | محرك سداسي | خيط جزئي | فولاد سبائك فئة 12.9 مطلي بالزنك (50 / عبوة)

Installed these in a press brake assembly and the hex drive seated perfectly without any stripping. The 140mm length gave just enough grip for the clamping load I needed.

I’ve been using these partially threaded bolts for a heavy-duty fixture at work, and the hex socket drive makes installation in tight spots much easier than standard hex heads. The zinc plating seems durable so far, and the 12.9 alloy steel feels solid—definitely up to the job.

Needed a longer bolt for a custom jig build, and these M10-1.5s at 140mm hit the spot. The partial threading made alignment easy, and the zinc finish has held up well against minor shop grime.
