براغي رأس مقبس M14-2 × 90 مم | محرك مقبس سداسي | خيط جزئي | فولاذ سبائكي فئة 12.9 مطلي بالزنك (25 / عبوة)

I needed high-strength fasteners for a jig I'm building, and these 12.9 alloy steel screws feel incredibly solid. The hex socket drive engages perfectly with my wrench, no slipping at all.

I needed these for a jig I'm building, and the hex socket drive made installation much easier than slotted screws. The partially threaded shank gives a really secure hold in the assembly.

The zinc plating on these M14-2 socket cap screws gives them a clean, polished look and I haven't seen any rust after a month in my jig setup. They drive in with a satisfying snugness and hold tight under vibration.
