براغي رأس مقبس M4-0.7 × 60 مم | محرك سداسي رأس مسطح | ملولبة جزئيًا | فئة 12.9 فولاذ سبائك مطلي بالزنك (200 / عبوة)

The hex socket drive seated perfectly on my driver, and the zinc plating gives them a clean, uniform finish that doesn't flake off during install. Partially threaded design held my precision assembly snug without any wobble, so these are doing exactly what they're meant to.

Waiting on a handful of these for a jig rebuild, and the 60mm length is spot on for reaching through two stacked plates. The zinc coating looks even and should hold up fine in my dry shop environment.

The hex socket drive on these M4s grabs the driver bit perfectly without any cam-out, and the 60mm length is just right for mounting jig fixtures. The zinc plating looks clean and consistent across all 200 screws in the bag.
