براغي ماكينة #10-32 × 4 بوصة | رأس مسطح محزز | ستانلس ستيل 18/8 (200/عبوة)

Needed a 4-inch machine screw for a tight bracket assembly, and these threaded in cleanly with no binding. The 304 steel holds up great in my damp garage. Much sturdier than the zinc-plated ones I used before.

The slotted heads on these #10-32 screws let me get a good grip with a standard flathead, and the 4-inch length was perfect for securing my deck hardware. They're definitely non-magnetic, which I tested out of curiosity, and the stainless steel feels solid enough for outdoor use.

These are exactly what I needed to mount a heavy bracket through some thick wood paneling. The flat head sits flush and the 18/8 stainless feels substantial.
