a.Through the tongue so the next board hides the fastener
b.Straight down through the face of each board
c.Through the groove edge only
d.Into the top surface at the center of each board
Giải thích
Blind-nailing drives fasteners at about 45 degrees through the tongue of each board so the adjacent board's groove conceals them, leaving a clean face with no visible nails. Face nailing, groove nailing, or center-face nailing would show fasteners or fail to lock the boards.
