Bold thread design that provides superior holding power
Patented 4CUT™ tip that ensures fast starts, reduces
installation torque and eliminates the need for pre-drilling
in most applications
Under-head nibs that offer greater control when
seating the head
Large washer head provides maximum bearing area
(0.75" head diameter)
Size identification on all SDWS screw heads
Double-barrier coating provides corrosion resistance equivalent to hot-dip galvanization, making it suitable
