براغي رأس أسطواني M6-1 × 16 مم | رأس زر محرك سداسي داخلي | كامل اللولبة | فولاذ سبائكي درجة 12.9 مطلي بالزنك (400/عبوة)

I needed a bulk pack for building jigs, and these M6-1 x 16mm socket cap screws from Class 12.9 steel are holding up perfectly under heavy clamping pressure. The hex socket drive makes installation quick with just an Allen key.

The hex drive on these M6 screws grabbed perfectly with my Allen key, no stripping even under high torque. I used them for a jig build and all 400 pieces had clean threads with consistent plating. Solid fit for precision work.

I needed a batch of strong fasteners for my jig builds, and these fully threaded 12.9 alloy steel screws are noticeably tougher than the usual hardware store stuff. The zinc plating has a clean, consistent finish that should resist rust nicely.
