مسامير ماكينة 1/4-20 X 3" | رأس مسطح فيليبس | فولاذ عادي (300 / عبوة)

Used a handful to secure a workbench top to a steel frame—the threads cut cleanly into pre-tapped holes with no binding at all. The 3-inch length gave plenty of grip for that 2x4 sandwich.

For the price of a decent lunch I got enough plain steel 1/4-20s to rebuild half my shed shelving, and the Phillips heads seated deep enough that my driver didn't strip a single one. The 3" length gives plenty of bite into 2x4s, and the threads cut clean even through painted lumber.

These are holding up my workbench leg brackets perfectly. The Phillips head drives smoothly without stripping, and the 3-inch length gives me plenty of grip into the 2x4s.
