براغي رأس أسطوانية M5-0.8 × 25 مم | محرك سداسي برأس مسطح | ملولبة بالكامل | فولاذ سبائكي فئة 10.9 مطلي بالزنك (600/عبوة)

For my jig build I needed a full box of M5s that wouldn't strip, and these Class 10.9s drove in clean with zero cam-out across all 600 pieces. The hex socket seats the Allen key perfectly, and the flat head sits flush in the counterbore every time.

The zinc plating has a nice uniform finish, and the hex socket drive seated perfectly on my wrench without any stripping. These M5s will last a long time on my shop fixtures.

Got three jigs bolted together this morning and the hex drive seated perfectly every time, no stripped heads. The zinc plating’s holding up nicely on the stainless bench, and at 600 per pack I won’t be reordering for a while.
