Joshua ★★★★★

The binding head sits flush nicely on my light-duty project, and the brass finish matches the vintage look I needed. Took a while to arrive, but the pack size was perfect for multiple small repairs.

Sebastian ★★★★★

These are exactly the right size for securing decorative brass nameplates, and the slotted binding head sits flush without snagging. The whole 800-count bag means I'll have spares for years.

Julian ★★★★★

I needed brass screws for a model ship project and these binding head slotted ones look sharp against the dark wood. The corrosion resistance is a plus since it’ll sit by the window.
