براغي رأس سداسية M16-2 × 100 مم | فولاذ فئة 10.9 عادي | ملولبة جزئيًا (15 / عبوة)

Picked up a pack of these for a heavy-duty shelving build, and the hex heads grabbed the socket without any slipping. The 100mm length and partial threading were exactly right for sandwiching two steel beams together. They threaded in smoothly and feel solid with the class 10.9 steel.

Installing a new piece of equipment, and these 100mm bolts threaded in smoothly without any binding. The partially threaded design made alignment much easier than fully threaded ones I've used before.

I used a pair of these in a heavy-duty jig I’m building, and the partial threads made alignment much easier than a fully threaded bolt. The hex head fit my socket perfectly without any wobble.
