براغي رأس مقبس M5-0.8 × 14 مم | رأس مسطح محرك سداسي | ملولب بالكامل | فولاذ سبيكة فئة 12.9 مطلي بالزنك (600 / عبوة)

I use these for building jigs in my workshop, and the flat head sits perfectly flush in countersunk holes. The zinc plating on the 12.9 alloy steel seems durable, no chips after tightening a few dozen.

The hex socket drive fits my driver bits perfectly without any wobble, and the zinc plating gives them a clean, uniform finish that resists fingerprints during assembly. For the price per piece on a 600-pack, these are a solid buy for anyone doing precision work.

I needed a bulk pack for jig assembly and these M5 socket heads drove in cleanly without a single strip. The zinc plating looks consistent and the 12.9 alloy steel feels noticeably harder than the standard hardware I’ve used before.
