براغي رأس سداسي M16-2 X 110mm | فئة 10.9 فولاذ مطلي بالزنك الأصفر | خيط جزئي (25 قطعة/عبوة)

I needed some heavy-duty bolts for a farm implement repair, and these partially threaded cap screws were exactly what the job required. The yellow zinc finish looks like it will hold up well against moisture, and the 10.9 grade steel gives me confidence they won't strip under load.

The hex heads fit perfectly on my socket wrench, and the 10.9 steel feels solid without any wobble during assembly. I used a dozen of them on a heavy equipment frame, and they torqued down exactly as expected.

The partially threaded design grabbed the threads perfectly on my fixture build, and the yellow zinc coating looks uniform across all 25 pieces. The hex heads seated cleanly with a socket wrench, no stripped edges or burrs to fight with.
