براغي رأس مقبس M6-1 × 16 مم | رأس منخفض محرك سداسي | ملولبة بالكامل | فولاذ سبائك فئة 8.8 (400/عبوة)

Used these to secure a jig on a drill press table, and the low profile head gave me just enough clearance for the workpiece. Threads cut clean and the black oxide finish hasn't chipped after a dozen tool changes.

Was a bit skeptical about the low profile working for my jig, but the hex socket grabs really well and there's no stripping. The 400 count should last me through several projects.

Used these to fasten a custom fixture on my mill table and the low head profile gave me the clearance I needed. The threads cut cleanly and all 400 pieces had consistent quality, which made assembly quick.
