براغي رأس أسطوانية M3-0.5 × 12mm | رأس مسطح محرك سداسي | ملولبة بالكامل | فولاذ مقاوم للصدأ 18/8 (1800/عبوة)

Needed a solid pile of M3s for jig building and these didn't disappoint. The 18/8 stainless finish is clean and uniform, and the flat heads seat flush without any burrs catching. Perfectly threaded along the full 12mm, which made quick work of a batch of precision clamps.

The hex socket drive made seating these into my jig plate effortless with a ball-end driver, no stripping even at snug torque. I've burned through cheaper packs before, but the 1800-count box and consistent 18/8 stainless finish justify the price if you do a lot of precision assemblies.

Used these for mounting a small CNC spoil board—the flat head sits perfectly flush, and the 18/8 stainless hasn't shown any corrosion yet. They thread smoothly into M3-0.5 tapped holes, no cross-threading issues. Exactly what I needed for tooling fixtures.
