Customer Reviews (4.8 / 5 · 5 reviews)

George ★★★★★

Packed 800 of these in a single bag, so I won’t be running out mid-project anytime soon. The flat head sits flush against the panel without any wobble, exactly what I needed for mounting brackets.

Thomas ★★★★★

The black oxide finish on these #4-40 screws really holds up well during assembly, and the flat head sits flush against the panel without sticking out. Perfect for those tight spots where you need a clean, secure fit.

Mia ★★★★★

Needed a bunch of tiny fasteners for an electronics enclosure and these did the trick—the flat heads sit flush perfectly and the black oxide finish doesn’t glare under work lights. The 800-count box means I’m set for a long time, and the Phillips drive grabs cleanly without stripping.
