Pheinox stainless steel screws are
another first from GRK. Pheinox screws provide a reasonably
priced alternative when only stainless steel will do.
Most hardened stainless steel screws are made of low
grade #400 stainless steel; which provides only limited
corrosion protection. By comparison, Pheinox stainless
steel screws are made of a hardened #305 or #316 material.
Pheinox screws are hardened and come with a lifetime
anti-corrosion warranty. Our special composition PHE
stainless steel is one of a kind. It is hardened and
GRK's patented R4 Counter Sinking
Rugged Structural Screws, and Trim
Head Screws are available in Pheinox stainless steel.
