Customer Reviews (4.8 / 5 · 5 reviews)

Amelia ★★★★★

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.

Ellie ★★★★★

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.

Christopher T. ★★★★★

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.
