براغي تثبيت برأس كوبي M3 X 20mm | فولاذ مقاوم للصدأ 316 (250 / عبوة)

The cup point bites into the shaft nicely and holds firm even after a few rounds of adjustments. The 316 stainless finish is smooth and clean, no burrs or rough edges on any of the 250 pieces.

The hex socket drive made tightening these in a cramped bracket much easier than I expected. The 316 stainless finish looks clean and seems like it'll resist rust well.

Finally got around to using these to rebuild some marine hatch hardware and the 316 stainless held up perfectly under saltwater exposure. The hex socket drive made it easy to torque them down in a cramped corner without stripping.
