براغي ماكينة #4-40 × 3/8" رقعة حمراء | رأس بان محرك فيليبس | ستانلس ستيل 18/8 (1000 / عبوة)

The red nylon patch on these #4-40 screws holds fast under vibration, which is exactly what I needed for securing a metal panel. The 18/8 stainless steel feels solid and corrosion-resistant, and having 1000 in one pack means I won’t run out mid-project.

I needed a bulk pack of small stainless screws for a cabinet project, and these #4-40 x 3/8" pan heads with Phillips drive have been perfect for securing thin metal panels without stripping. The 18/8 stainless material feels solid and resists rust better than the old zinc-coated ones I used to buy.

The red thread-locking patch is a huge time saver, no need to dab Loctite on each one. These pan head screws fit perfectly into the front panel of my small control box. Just the right size for #4-40 holes.
