براغي ماكينة M4-0.7 X 70mm | رأس مسطح محزز | ستانلس ستيل 18/8 (200/عبوة)

Slotted drive on these is actually a nice throwback, and the 18/8 stainless holds up well in the damp area where I mounted them. Non-magnetic was a pleasant surprise, too, so they don't grab at my tools. For 200 pieces, this is a solid buy.

I needed a long 70mm screw for a custom bracket and these M4s fit perfectly. The flat head sits flush in my countersunk holes and the stainless steel finish looks clean.

The slotted drive cut is clean and deep, so a standard flathead bit grabs it without slipping even when I'm torquing these into steel brackets. The 18/8 stainless finish has held up through a few wet weeks outside with zero rust spotting, which is exactly what I needed.
