Customer Reviews (4.6 / 5 · 5 reviews)

Owen ★★★★★

The slot on these pan heads cuts perfectly true, so my flathead driver doesn't slip even when I'm torquing them into hardwood. A full 300-count box means I'll be set for every indoor project for a long while.

Brian S. ★★★★★

I needed a full box of these for a shelving project, and the 300 count is perfect—plenty of extras for future repairs. The threads catch smoothly in the pre-tapped holes, no jamming or cross-threading issues. Fine for indoor use as described, just remember they’re plain steel so keep them dry.

Jacob ★★★★★

The threads cut cleanly into the steel with no binding, and the slotted heads seated flush without stripping even when I torqued them down pretty hard. For the price on a full 300-pack, these plain stainless-free screws are a solid choice for any indoor project.
