براغي رأس مقبس M24-3 × 80 مم | محرك سداسي برأس مسطح | ملولبة بالكامل | فئة 12.9 من سبائك الصلب مع أكسيد أسود حراري (10 / عبوة)

These class 12.9 screws held up perfectly when I used them to secure a heavy jig on my milling table—no stripping or deformation at all. The hex socket drive made torquing them down with an Allen key quick and precise.

Used these to secure a heavy jig on my mill table, and the hex socket drive made installation easy even in tight spaces. The black oxide finish seems durable and has held up well against minor shop grime so far.

The black oxide finish on these M24-3 screws looks clean and professional, and they drive in smoothly without stripping. Worked perfectly for securing a jig I built for my drill press. My only minor gripe is the packaging could be sturdier for the weight of ten large screws.
