鋅合金口袋螺絲

These are my go-to for any indoor build now; the self-tapping tip grabs instantly and the zinc coating holds up fine in my workshop. A hundred screws for the price means I don't wince when I drop a few under the bench.

Grabbed a box for a bookshelf project and the zinc coating has held up fine in the garage humidity. They drive in clean without stripping, even into hardwoods, and the price for the count is hard to argue with.

The coarse threads bit into the plywood without splitting, and the zinc coating held up fine during assembly in my garage. For the price, these are a solid choice for indoor builds where rust isn't a huge worry.
