Review on 🔩 Premium Screws with Coarse Thread for Easy Tightening - Number Screwdriver Compatible by Daniel Aboubakar

These are Square Shank Coarse Thread Self Tapping Pan Head Stainless Steel Screws. (They are NOT countersunk screws.) Stainless steel screws are softer than most other screws; Consequently, a square shank head is more prone to deformation when driving a screw, especially when reused. Use strong pressure and a fresh bait for the best chance of success. I would only use them for applications where weather resistance or aesthetic considerations justify choosing a stainless steel. The heads appear to be slightly larger than other #10 bolts in my shop; This larger diameter is probably better for spreading the load on softwood, but you may need to use a different countersink than you would normally use for hardwood. They arrived in a plastic case, which is ridiculous for this purpose. But for another use it would be great - so I was disappointed that mine (like others) arrived broken and therefore unusable.
