براغي قطع خيط من النوع F #10-32 × 3/8 بوصة | رأس مسطح مع فيليبس | فولاذ مطلي بالزنك (2000 / عبوة)

Used these for mounting a metal electrical box to a stud, and the self-cutting threads worked perfectly without pre-drilling. The zinc coating seems consistent across all 2,000 pieces, and none were bent in the box. Saved me a ton of time on a big project.

Finally found screws that actually cut clean threads into steel without stripping, and the zinc coating on these is holding up nicely in my damp garage. Used a full box on a truck body repair and every single one seated flush.

The zinc plating is holding up nicely so far, no rust after a few weeks in my damp garage. The phillips head grabs the driver bit firmly, and the flat head sits flush in the sheet metal. A full 2000-count box means I'm set for a long time.
