مسامير رأس مقبس M6-1 × 45 مم | رأس مسطح محرك سداسي | مدورة جزئياً | فولاذ سبائك كلاس 12.9 مطلي بالزنك (200/عبوة)

Pulled three out of the package for a machine guard assembly and the hex socket seated perfectly with no stripping. The 45mm length was exactly what I needed for this jig, and the zinc coating gives them a clean, uniform look. These are clearly built for precision work.

I've been using these in a jig setup and the flat head hex socket drive makes them easy to get flush without stripping. The zinc plating seems durable and they thread smoothly into tapped holes.

These are exactly what I needed for my precision assembly work — the 12.9 alloy steel feels rock solid and the zinc plating gives them a clean, uniform finish. The partially threaded design grabbed perfectly in my fixture, and the hex socket seated without any wobble.
