براغي ذات رأس أسطواني M12-1.75 × 35 مم | محرك سداسي برأس كروي | ملولبة بالكامل | فئة 10.9 من سبائك الصلب مطلية بالزنك (100 / عبوة)

Used a few of these on a custom jig I'm welding up, and the zinc plating held up nicely against the shop grime. Fully threaded means I could cinch down a spacer without hunting for a longer bolt. The hex socket drive seated cleanly every time, even with a worn-out Allen key.

I needed some high-strength fasteners for a jig I was building, and these M12 alloy steel screws fit perfectly. The hex socket drive makes them easy to tighten in tight spots, and the zinc plating looks clean and uniform.

Threads are clean and consistent across the whole package, and the zinc finish feels even from head to tip. Fit my fixture plates perfectly with a hex key, no wobble or stripped edges. For 100 pieces at this price, these are a solid buy for any tooling shelf.
