Daniel ★★★★★

Used these to mount some conduit brackets in the garage, and the flat heads sit perfectly flush in the channel. The 3-1/4 inch length was just right for going through the bracket and into the stud. Nice to have a full box of 200 for future projects.

Penelope H. ★★★★★

Installed a new storm door latch, and the 3-1/4" length was just right for penetrating the thick frame. They drive in smooth and the slotted head grabs my screwdriver firmly. Nice to have a whole box for future projects.

George ★★★★★

Having a box of these #10-24 screws on hand saved me a trip to the hardware store—the 3-1/4" length fits exactly what I needed for securing some wooden brackets. The slotted drive head works fine with a standard screwdriver, and the zinc coating gives me peace of mind for a few outdoor repairs.
