مسامير غطاء مقبس M16-2 × 130 مم | محرك سداسي المقبس | ملولبة جزئيًا | سبيكة فولاذ درجة 8.8 مؤكسدة حرارية سوداء (25/عبوة)

These bolts fit perfectly into my jig setup, and the black oxide finish gives them a nice, tough look. The hex socket drive made them easy to tighten with a standard Allen key.

The partially threaded design made it much easier to get these M16 bolts started into my jig's threaded hole before the full shank engaged. They fit the hex socket perfectly with no slop, and the black oxide finish looks clean and professional. Exactly what I needed for heavy-duty tooling assembly.

These black oxide screws threaded into my jig perfectly without any binding, and the hex socket drive made installation a breeze. I used them for a tooling fixture and the class 8.8 steel feels solid enough for daily use.
