براغي رأس مقبس M6-1 × 70 مم | محرك سداسي | ملولبة جزئيًا | فئة 12.9 فولاذ سبائك مطلي بالزنك (100 / عبوة)

These bolts seated cleanly in my jig without any thread binding, and the 70mm length was perfect for the assembly I was working on. The hex socket drive makes them easy to cinch down tight without stripping.

The zinc plating is flawless—every single screw in the pack threads smoothly without any gritty resistance. Used a full bag on a jig build and torqued them down hard, not one stripped or snapped.

Installed these in a precision assembly for a small automation project, and the hex socket drive grabbed firmly without any stripping. The 12.9 alloy steel feels noticeably tougher than standard screws I've used, and the zinc plating has held up well against a little moisture in the shop.
