No corrosion after 6 months

Installed these in a humid bathroom renovation half a year ago. Still shining like new with no green oxidation or rust. Highly recommended for wet areas.

Excellent quality brass

These screws are exactly as described. The brass is solid and not plated, which is crucial for my marine restoration project. The threads are clean and cut perfectly.

Perfect fit for vintage furniture

The golden color matches my antique hardware perfectly. The pan head looks very professional, and the cross recess didn't strip even under high torque.

Great value for bulk buying

Bought these for a large electrical panel assembly. The inclusion of washers and nuts saves a lot of time. One star off because the box was slightly dented on arrival, but the contents were fine.

Good product, slow shipping

The screws themselves are high quality pure brass. However, the shipping took longer than expected for a domestic order. Product gets 5 stars, logistics gets 2.
