براغي رأس مقبس M4-0.7 × 18 مم | رأس زر مع محرك سداسي | ملولبة بالكامل | فئة 12.9 من سبائك الصلب مطلية بالزنك (600 / عبوة)

The hex socket drive on these M4 screws made them a breeze to tighten in tight spaces on my CNC jig. The zinc plating on the 12.9 alloy steel shows a clean, consistent finish and the threads are perfectly formed through the full 18mm length. For a batch of 600, the price per screw felt very fair.

The hex drive grips perfectly without stripping, which is crucial for my precision jig setup. These M4x18mm screws came nicely plated and all 600 pieces were consistent in thread quality. A solid buy for anyone building tooling or fixtures.

These button heads are perfect for my jig builds—the zinc plating gives them a clean, consistent finish that doesn’t gum up the hex socket. I’ve already used half the pack on a precision assembly and haven’t had a single issue with stripping or fit.
