#10-32 X 9/16" マシンスクリュー | 100度フラットヘッドプラスドライブ | 18/8 ステンレス鋼 (600 / Pkg.)

I've been using these #10-32 screws for mounting electrical panels in a washdown area, and the 18/8 stainless steel shows no signs of rust after several months. The Phillips drive takes a bit of care to avoid camming out, but at this price for 600 pieces, it's a solid value.

I needed a bulk pack of #10-32 flat heads for some outdoor equipment, and the 100-degree countersink on these sits perfectly flush in the metal. The 304 stainless feels solid and non-magnetic, which is exactly what I wanted for washdown areas.

Finally found a stainless machine screw that doesn't strip at the first sign of torque—these #10-32s hold tight even under a power driver, and the 100-degree flat heads sit perfectly flush in my outdoor cabinet hinges. The 600-count pack means I won't run out mid-project either.
