براغي رأس أسطوانية M5-0.8 × 22 مم | محرك سداسي برأس كروي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 مطلي بالزنك (400/عبوة)

The hex socket drive seated perfectly with my Allen key, and the zinc plating looks clean and even across all 400 pieces. Threads ran smooth into my tooling fixtures without any binding, so this batch is doing exactly what I needed.

Needed a batch of 22mm screws for a jig I was building, and these Class 12.9 zinc-plated ones are definitely tougher than the usual hardware store stuff. The hex socket drive feels crisp and didn’t strip even under some heavy torque.

I’ve been using these for tooling setups and the hex drive makes installation smooth without cam-out. The 12.9 alloy feels tough under torque, and the zinc plating hasn’t shown any rust after a few weeks in my shop.
