براغي غطاء مقبس M16-2 × 55 مم | محرك مقبس سداسي | ملولب بالكامل | فولاد سبائكي فئة 12.9 مطلي بالزنك (25 / عبوة)

Installed these in a jig I’m building, and the hex socket drive made tightening them down in tight spots a breeze. The fully threaded length gives me plenty of grip for adjustments.

The zinc plating is holding up nicely after a week of use in a damp shop, and the 12.9 alloy steel feels seriously rigid. Threaded them into an existing fixture with zero binding—exactly what I hoped for.

The hex socket drive on these screws made tightening them in tight spots on my jig much easier than with a standard hex bolt. The 12.9 grade alloy steel feels incredibly robust for the price, and the zinc plating looks clean and consistent across all 25 pieces.
