براغي رأس سداسية M20-1.5 × 90 مم | فئة 8.8 فولاذ عادي | سنون جزئية (25 / عبوة)

Perfect thread engagement on the partially threaded shaft for my industrial jig setup. The hex heads hold firm under torque without stripping, and the class 8.8 steel feels rugged enough for repeated heavy use.

These M20 hex heads threaded into my equipment mounts without any binding, and the partial threading grabbed just right for a snug fit. Class 8.8 steel feels plenty rigid for the torque I put on them with a socket wrench. Exactly what I needed for the assembly job.

Used these to bolt down a heavy workbench frame and the hex heads grabbed a socket wrench without any slipping. The class 8.8 steel feels solid enough for the torque I put on them, and the partial thread gave just the right grip length for thick brackets. Pack of 25 is plenty for a few jobs.
