Great item
I needed to secure a stainless steel sheet to a metal frame. The item is more than capable of drilling into both metal materials with little effort. Amazing, will definitely buy more!

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

Did the Job
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.

A Good Fit for anything
Package arrived early, intact and product fit for purpose. Have used some to great effect for attaching safety/warning notices to square posts set in the ground, they also look in-sync with the notices, I am sure I shall find many other uses for these versatile screws.
