براغي رأس مقبس M16-1.5 X 50mm | محرك مقبس سداسي | خيط كامل | فئة 12.9 سبائك الصلب مطلي بالزنك (25/عبوة)

Installed these in a custom jig for a milling fixture and the 12.9 alloy steel threads cut cleanly without any binding. The zinc plating on the heads hasn't shown a speck of rust after a few weeks in the shop, which is exactly what I needed.

The hex drive on these M16 screws grabbed my driver perfectly without any cam-out, and the zinc plating looks clean and even across all 25 pieces. I used them to rebuild a fixture for a press jig, and they torqued down smoothly to spec.

The hex socket drive on these M16 screws is crisp and doesn't strip at all during installation, which is exactly what I needed for jig assembly. They hold firmly in my tooling setup and feel solid for the price.
