1/2-13 × 2-1/2" براغي ماكينة | رأس مسطح مشقوق | ستانلس ستيل 18/8 (100 / عبوة)

The slotted head caught a flathead screwdriver cleanly on every single one of the hundred, and the 18/8 stainless steel feels reassuringly solid. I’ve got them holding a gate hinge outdoors and they haven’t shown a speck of rust after a few weeks of rain.

Used a handful of these to secure a heavy-duty shelf bracket in a damp garage, and the 18/8 stainless steel hasn't shown a speck of rust after weeks. The flat head sits flush in the countersink, which made for a clean finish.

The slotted heads on these 1/2-13 machine screws are deep and well-formed, so my screwdriver didn't cam out once during assembly. I'm using them on a small outdoor gate, and the 18/8 stainless finish looks clean and hasn't shown any rust after a few wet days.
