Technical Data
These 1-1/4″, #10 Tile Underlayment Screws from QuikDrive (CB3BLG114S) are for attaching fiber-cement board to-wood
They have a .375″ ribbed wafer head and require a #3 undersized square drive. They have C-3 coating, a mechanical galvanization which provides a protective zinc and tin coating over base metal to delay rusting
The coating is applied by mechanically tumbling zinc and tin powder with the base metal and non-metallic impact beads. (Results in less than .1% surface red rust at 1000 hours of ASTM B117 salt spray test)
These screws come in a straight collation and meet the requirements of ANSI 108
