براغي رأس مقبس M5-0.8 X 6mm | رأس مسطح محرك مقبس سداسي | ملولبة بالكامل | فئة 12.9 فولاذ سبائك مطلي بالزنك (600 / عبوة)

Packed them up for a hex-drive fixture and the zinc plating stayed flawless through a week of assembly. The 12.9 alloy steel gives a satisfying bite into the tapped holes without any stripping, and the flat heads sit flush like a dream.

Used these for mounting jig plates on my drill press table and the flat head sits perfectly flush. The zinc coating looks uniform and the 12.9 grade steel feels rock solid under torque.

Got these for a jig I’m building, and the 12.9 alloy steel feels seriously tough for the price. The hex socket drive seated cleanly with no stripping, though the zinc coating is a bit thinner than I’d like on a few pieces. Pack of 600 is a solid deal if you’re doing repeated assemblies.
