Customer Reviews (4.6 / 5 · 5 reviews)

Leo ★★★★★

The flat undercut head sits flush in my aluminum panels, and the Phillips drive doesn't cam out under torque. These are exactly the right size for a tight spot where a standard screw head would interfere. Have already gone through half the bag on one project.

Edward V. ★★★★★

Finally found the right size for a small electronics project — these #4-40 screws cut their own threads without stripping, and the flat undercut head sits flush perfectly. The Phillips drive made it easy to seat them even in tight spots.

Victoria ★★★★★

The trivalent zinc finish is a nice touch—these tiny screws don't show any rust even after sitting in a damp toolbox for a week. The flat undercut head seats flush perfectly in the thin plastic panels I'm using them on, and the phillips drive bites without stripping.
