### ⭐⭐⭐⭐⭐ Great item

### ⭐⭐⭐⭐⭐ Good screws
*by T***K on 25 January 2024*

Screws as advertised, measurements were correct, works well and seems durable. I used them to drill into 2mm aluminium

### ⭐⭐⭐⭐ Did the Job
*by A***R on 12 August 2025*

Happy with item, although one small point, the drawing shows 9.8mm diameter for the screw wafer head, the ones delivered were 10.4mm.. I chose these, as they needed to fit into a 10mm recessed diameter hole. A bit brute force and they went in.
