SPAX® Coating Options and Corrosion Resistance

For Interior Applications

Zinc and Yellow Zinc:  Provides a basic level of corrosion resistance against red rust caused by exposure to typical moisture/humidity levels in interior environments.

For Exterior Applications

HCR® (High Corrosion Resistance):  Provides good/typical level of corrosion resistance against red rust in most exterior environments, and is approved for use in treated lumber.

HCR-X™ (Extra High Corrosion Resistance):   A proprietary coating system developed by SPAX® that provides superior corrosion resistance against red rust compared to SPAX® HCR®  coating and most other coating systems used on threaded fasteners.  It is code compliant for above ground use only treated lumber applications in coastal (salt water) environments.  Not recommended for use in cedar and redwood. "It provides the next best level of corrosion resistance to 304 Stainless Steel at an affordable price".

304 Series Stainless Steel:  SPAX® construction screws made of 304 series stainless steel provide a premium level of corrosion resistance against red rust over SPAX® HCR® and HCR-X™ coatings and other applied coatings on threaded fasteners.
