W-Cut is a patented thread design which acts like a
saw blade, cutting through any fibrous materials with
ease. This unique design reduces the amount of torque
required to install the screw, and maintains a high
pull out strength. By cutting through, rather than pressing
fibers aside, the W-Cut also reduces material splitting.
NO strip drive
The W-Cut design is available on all
GRK screws 1 1/4" and longer. GRK's Zip Tip is
designed for fast starts ain any fibrous materials.
