مسامير ماكينة 1/4-20 × 5/16" | رأس دائري مشقوق | ستانلس ستيل 18/8 (400/عبوة)

For my outdoor repair project these were perfect, the stainless steel held up well through a rainstorm. The slotted drive made them easy to secure in tight spots.

Used a handful of these for a outdoor furniture build and they threaded perfectly into the pre-tapped holes. The 18/8 stainless held up great after a week of rain—no rust.

The slots in these screws are cut deep and clean, so my slotted driver bites firmly without camming out. They're genuinely non-magnetic, which saved me from a headache when working near sensitive electronics. Perfect for small enclosures where every millimeter counts.
