Description
SPAX® Hex Washer Head construction fasteners with HCR® coating are intended for wood-to-wood connections in exterior structural applications when attaching treated lumber components. These fasteners are designed with a hex head conventional driver system along with a built in washer for applications requiring additional surface area under the head for superior pull-down force. Ideal for deck ledger attachment. Often used for blind, high torque applications where additional engagement of socket to screw head is needed.
Material & Coating
Cold-rolled “carbon steel” wire heat treated to Grade 5 durability and plated with an HCR® (High Corrosion Resistance) double barrier coating. “HCR” is tested and recognized for use in ground contact pressure treated lumber for exterior, freshwater general construction applications (e.g. AWPA UC1-UC4A, UCFA).
Note: We are transitioning from green to black HCR during mid-June 2022 - New Color Matches Trending Exterior Projects!
