New Pressure-Treated Lumber
There are improvements in wood-preserving technology. They are in response to a growing market demand for less toxic, more environmentally acceptable preservatives for wood.

These new treatments include ACQ and Micronized Copper. ACQ stands for Alkaline Copper Quat. The central ingredient is 100% recycled copper. Alkaline is a natural base, and quat is a fungicide that attacks decay organisms. Micronized Copper treatments utilize copper but in micro-sized particles.

Phillips Fastener is pleased to announce all of the Phillips II Plus Wood Screws and Phillips II Plus Composite Screws are formulated to work with all types of pressure-treated lumber. All three colors – red, tan, and green – can be used.

Tested to Building Code Standards
Phillips II Plus Wood Screws and Phillips II Plus Composite Screws have passed AC257 testing by an ICC-accredited laboratory. Tested to exposure condition 4 (the most severe category of this test).

Lifetime Guarantee
Phillips Fastener screws are made of high quality hardened steel and are coated with our proprietary barrier coating. The coating is designed to last for the lifetime of your project and will offer corrosion resistance equal to or better than hot-dipped, galvanized nails. The screws are not intended to last longer than the life expectancy of your wood. The reuse of screws is not recommended and will void any guarantee. Phillips Fasteners’ Stainless steel is recommended for coastal and water areas.

Phillips Fastener coating will not prevent staining, streaking or extractive bleeding related to high tannin content lumber such as cedar, redwood and cypress. Properly treating and sealing the lumber in accordance with the manufacturer’s recommendations is required.

Unless otherwise specified as structural screws, screws are not designed for use in metal hangers, railing supports or for structural applications. Consult your building code and your board manufacturer’s recommendation for proper fasteners and fastening methods.

Note: NOT all screws made by Phillips Fastener are guaranteed. Refer to each product for their feature and benefits including corrosion resistance.

Five Basic Steps for KwikTap Screws

  1. Concrete screws require 1" minimum embedment.
  2. You must pre-drill a proper sized hole, and it must be a minimum of 1/4" deeper than the screw.
  3. The drilled hole must be cleaned of debris after drilling. If the dust that is caused by drilling is not removed, it can cause the screw to bind and be unable to be driven in.
  4. Drive the screw in flush to the concrete. Do not overtighten as that will strip the concrete.
  5. Always follow local building code.
