براغي رأس سداسي M16-2 × 170 مم | فولاذ فئة 10.9 أصفر زنك | ملولب جزئيًا (10 / عبوة)

These are perfect for my shop press build; the 170mm length gave me just enough thread engagement through the frame. The yellow zinc coating looks quality and should hold up well against minor rust.

Got these for a heavy machinery project we're doing at the shop, and the class 10.9 steel yellow zinc finish is holding up great against grime and vibrations. The hex head takes a socket perfectly too, no slipping at all.

The partially threaded shaft grabbed just right when I torqued them into the equipment frame—no slipping or stripping at all. Class 10.9 steel feels plenty tough for the heavy assembly work I've got them in.
