Customer Reviews (4.6 / 5 · 5 reviews)

David X. ★★★★★

The flat 100° head sits perfectly flush in the countersunk holes I drilled, and the 18/8 stainless steel feels solid and corrosion-proof. These #4-40 screws threaded smoothly into my enclosure brackets without any binding—exactly what I needed.

Michael Q. ★★★★★

Just finished a panel assembly job and these 18/8 stainless screws drove in cleanly with zero cam-outs. The 100° flat heads sit perfectly flush in the countersinks, which is exactly what I needed for a tight enclosure fit.

Richard ★★★★★

Had to replace a bunch of stripped screws in an old electrical panel, and these #4-40's threaded in perfectly and held tight. The 18/8 stainless feels like it'll outlast the equipment itself, and getting 2,000 in one box means I won't run out anytime soon.
