براغي رأس مقبس M5-0.8 × 150mm | محرك مقبس سداسي | ملولب جزئيًا | فولاذ سبائكي فئة 12.9 مطلي بالزنك (50/عبوة)

The zinc plating on these 150mm screws is flawless—no flaking even when I torqued them into my jig setup. At 12.9 grade, they’ve got that reassuring heft, and the hex socket grabbed the Allen key perfectly every time.

These are the first 12.9-grade cap screws I’ve used that didn’t strip when torqued down hard in a steel fixture. The zinc plating’s held up well after a few assembly/disassembly cycles, and the hex socket drive lets you get a real bite without cam-out.

I needed extra-long screws for a jig I’m building, and these 150mm ones fit perfectly with the partially threaded design. The zinc plating looks clean and should hold up well in my shop.
