براغي رأس أسطوانية M12-1.75 × 65 مم | محرك سداسي | خيط جزئي | فئة 8.8 فولاذ سبائكي مطلي بالزنك (50 / عبوة)

Threaded all the way down would have been nice, but these are exactly the right length for the jig I’m building and the hex socket drive makes install a breeze.

Took a gamble on these for a jig build and the hex socket drive seated perfectly with no stripped corners, even under decent torque. The zinc plating looks uniform across all fifty pieces, so they should hold up fine in the shop.

The partially threaded shank on these M12 screws made aligning my jig fixture so much easier than fully threaded ones. They torqued down smoothly with a hex key and the zinc plating looks clean. Exactly what I needed for a heavy-duty tooling project.
