براغي رأس سداسي M16-2 × 150 مم | فولاذ فئة 10.9 زنك أصفر | ملولب جزئيًا (25 / عبوة)

Installing these on some heavy equipment and the partially threaded design made aligning them into the mounting holes much simpler than fully threaded bolts. The yellow zinc finish looks like it will hold up well against the dirty shop environment.

The hex head on these gave me a solid grip with my socket wrench, and the yellow zinc finish looks clean and resists rust well. I’m glad they’re partially threaded too, since I needed the smooth shank to align a couple of heavy brackets.

The yellow zinc finish on these M16s handled a week of outdoor assembly without a speck of rust, and the class 10.9 rating gave me confidence torquing them down hard. The partial thread let me grip the frame snug without bottoming out—exactly what I needed for the jig.
