Fastap Plus No. 10 X 4-1/2 In. L Square DuracoatXT Wood Screws 6 Lb 250 Pk

The ultimate self drilling woodworking screws with almost 35 years of unsurpassed performance and long term reliability. Built and tested to outperform any other exterior type screw in any material type in the harshest of outdoor environments. Fastap DuracoatXT exterior screws have tested at 3 times greater in corrosion protection than any other exterior screw in the market. ASTM salt spray tested at 3,636 hours with no red rust after being installed and withdrawn in pressure treated wood. Then the same screws were subjected to 40 Kesternich cycles testing, again with no red rust present. At least 3 times the protection is of great value to the end user. Construction applications in coastal environments subject to constant salt fog exposure is commonplace. Our DuracoatXT coating is not subject to limitations on “distance” from an ocean coastline. Almost all other exterior screws in the market note a disclaimer somewhere on their packaging – “not to be used within 5 miles of the ocean and/or coastline”. This kind of limitation is very restrictive and difficult to “measure” when in use in this type of environment. All Fastap exterior screws do not have this limitation.

Self drilling in all wood types regardless of density without splitting

Self countersinks with locking nibs underneath the head to prevent overdriving without splitting the wood surface

More head material increases head strength during installation and after, which eliminates head popping if materials contract and expand during weather/temperate changes in a variety of environments

Refined power point design delivers increased holding power and pullout load value in green/soft woods in damp environments, holds super tight in dry environments

The DuracoatXT coating process is environmentally safe due to no zinc which contributes to metals pollution in any water table and DuracoatXT is applied at a low heat process making it pliable & flexible and impact resistant

After being installed and withdrawn subject to friction on the thread surfaces, DuracoatXT corrosion performance exceeded 3,636 hrs in 5% salt spray tests and 40 Kesternich cycles after that with no red rust, exceeds all other coating types

DuracoatXT is totally compatible with cedar, redwood and pressure treated lumber with no chemical reactions and doesn’t cause bleeding when in contact with Tannins

Larger wire diameters for greater shear strength, with longer shanks for tighter draw-down delivering a tighter fit
