براغي رأس أسطوانية M4-0.7 × 14 مم | رأس زرية بمحرك سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 مطلي بالزنك (600 / عبوة)

I needed a reliable fastener for a precision assembly project, and the consistent threading on these M4 screws made installation smooth and secure. The zinc plating gives them a nice, clean look, and the hex socket drive held up well under moderate torque.

The hex drive on these 14mm M4 screws really grabs the bit without stripping, which is perfect for my jig builds. They're zinc-plated and feel solid, exactly what I needed for tooling fixtures.

The hex socket drive on these M4 screws made installation with a ball-end driver really smooth, and the zinc plating gives them a clean, uniform finish. They fit perfectly into my jig assembly without any binding. Only giving 4 stars because the box they came in was slightly crushed in transit.
