Henry ★★★★★

The slotted heads on these machine screws fit my standard flathead driver perfectly, and the zinc plating looks clean and consistent across all 100 pieces. Used a handful to secure some brackets in my garage, and they threaded smoothly into the pre-tapped holes without any binding.

Isabella ★★★★★

I needed a decent batch of 3/8-16 screws for some light metal framing repairs, and these worked perfectly. The zinc coating looks even and should hold up fine in my garage. No stripped heads or bent shafts on the whole pack.

Charlotte Y. ★★★★★

The threads cut cleanly into my steel brackets without any binding, and the zinc coating has held up fine even on my damp garage shelf. For the price, getting a full hundred of these slotted round heads feels like a solid deal.
