These are high quality as none of them stripped out like fasteners with inferior metals tend to do. Replaced 300 screws on the exterior of my old shed before painting it.

This works well for repairs in ducting and sheet metal work.

Metric heads but they include the proper driver with a very weak magnet that fell out mid way through the project. The main issue was the tips would easily dull or chip prior to making it through some 14 gauge structural C channel. I ended up pre-drilling all the holes to speed up the project. They are cheaper than competing items at the big box hardware stores but time is money...

These screws were lost in transit but showed up today, this is great news because I was waiting on them for an urgent project. The screws feed quickly and drill there way easily. I’m using these screws to attach end walls to a Versatube structure, the screws fasten 2x 4 lumber to the metal frame to enclose the building. They include a drive adaptor.
