براغي رأس سداسي M30-3.5 × 80 مم | فئة 10.9 فولاذ مطلي بالزنك الأصفر | ملولبة بالكامل (5/عبوة)

The hex heads took a 46mm socket perfectly, and the class 10.9 steel definitely feels tougher than the grade 8.8s I usually grab. Fully threaded meant I could cinch down a thick flange plate without any shims. Even the yellow zinc has a nice, even finish that should hold up well in the shop.

The yellow zinc coating on these M30 screws looks well applied and should resist rust well in my shop. Used them to fasten a heavy-duty bracket to a steel frame, and they seated perfectly with a socket wrench. Exactly the high-strength fasteners I needed for the job.

The 10.9 grade steel on these hex bolts is noticeably harder than standard hardware—my impact gun seated them into a steel frame without stripping. The yellow zinc finish also looks clean against the equipment.
