Customer Reviews (4.4 / 5 · 5 reviews)

Victoria ★★★★★

Needed a solid batch of #4-40 screws for a control panel project, and these 18/8 stainless ones are exactly what I was after. The phillips drive bites nicely without stripping, and that 1000-count package will last me through several builds.

Ava V. ★★★★★

The flat undercut head sits perfectly flush in my aluminum panel—no snagging on cables at all. Phillips drive bit caught cleanly on every single one, and after a month in a humid garage, none of these 18/8 stainless screws show a hint of corrosion.

Owen U. ★★★★★

The 18/8 stainless steel feels solid and corrosion-resistant, perfect for outdoor enclosures. Needed exactly these for a panel project, and the phillips drive made installation quick with no stripped heads.
