Countersink 1×4 strapping
I am building my rain-screen with 1×4 strappings to support 1 1/2″ foam and James Hardie sidings. I will be using FastenMaster Headlock 6″.
The screws need to be countersink into the strapping. The head is 5/8″. I can not find a countersink drill bit set that is over 1/2″…
I can use a 14 drill bit with a countersink in 1/2″, then finish with a countersink in 5/8″, but this is really time consuming.
How are you guys preparing your strappings?
