Review: Great product - Excellent product, 100% no breakages. Went in well.
Review: Good quality screws - So far I'm really pleased. Time will tell. I had bought my kids a TP pirate boat for the garden. After a couple of years the cheap screws that came with it were rusty and most were snapping in half so I've had to gradually replace all 270 (ish) of them. I wasn't sure how many I would need but have ended up buying 4 packs and it wasn't quite enough so I've had to buy 2 more packs to finish the job. Fingers crossed!

### ⭐⭐⭐⭐ Shed roof and panels
*by A***R on 28 December 2024*

Used these for a shed, solid little fixtures, worked well with an impact driver (pilot holes pre-drilled), non magnetic but a sharp clean screw. Time will tell if they are weather proof, installed these in the Autumn.
