براغي رأس مقبس M4-0.7 × 35 مم | رأس مسطح محرك سداسي | ملولبة جزئيًا | فئة 10.9 سبيكة فولاذ مطلية بالزنك (400/عبوة)

Had to swap out some worn bolts on a jig and these threaded in clean without binding. The 35mm length was exactly what the assembly called for.

The partially threaded design made aligning these in a tight jig setup much easier than fully threaded screws. After using a handful on a small assembly project, the zinc plating seems to hold up well against minor scuffs. A solid batch for precision work.

The hex socket drive on these M4 screws fits perfectly with my ball-end drivers, making them much easier to install in tight spots on my jig. The class 10.9 alloy steel feels tough and the zinc plating looks clean. Exactly what I needed for precision assembly work.
