براغي رأس سداسي M20-1.5 × 90 مم | فولاذ فئة 10.9 مطلي بالزنك | خيط جزئي (25 / عبوة)

Used these for a press build and the zinc plating held up well against a few drops of oil. The partial thread was perfect for aligning the joint before cinching down.

Had to torque these to spec on a heavy jig, and the zinc plating held up perfectly—no galling on the threads. The partially threaded design made alignment a breeze for that deep 90mm reach. Exactly what I needed for industrial assembly.

Installed these on a press project and the M20-1.5 threading was precise, no cross-threading issues. The partial thread design made assembly easier than with fully threaded bolts.
