So far good paint on screws

Great product so far, just installed roof and the paint quality seems to be good, using an impact to drive them in and heads of screws still have the paint

Great Metal Roofing Screws

I paid a little extra for the ZXL Steelbinder Metal Roofing Screws. They worked great for drilling into the heavy gauge steel purlin. No pre-drilling necessary. Looks like they will hold up for many years to come.

Worked great for a tin roof and don't have to worry bout the sun ruining the rubber:)
