براغي رأس سداسية M4-0.7 × 22 مم | فئة 8.8 فولاذ عادي | خيط كامل (7300/عبوة)

Replacing the bolts on an old milling machine, these M4 screws threaded in smoothly the entire way. The hex head fit my socket perfectly without any slipping. This pack of 7300 should last through several restoration projects.

I needed a batch of M4 screws for a jig I was building, and the fully threaded design on these made adjustments easy. The 22mm length was just right for several overlapping plates, and the hex heads grabbed the wrench cleanly with no stripping.

These M4 bolts held up perfectly when I torqued them down on a jig fixture. The class 8.8 steel feels solid, and the hex head didn't strip even with repeated use. Exactly what I needed for industrial assembly.
