Simpson stainless steel cement board siding screws

Oct 23, 2019 | By Larry

I have used these screws to install James Hardie board soffit panels and will soon use them to install Hardie board plank siding. Great product, great price and availability at Manasquan, and fast shipping. Thanks

Great product

Used these to install Hardie Plank on my shed. Was leery that they were square heads as they sometimes strip but no issues. I go with torx now. Anyway, I only wish these were available when I sided my summer house on the water.
