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 great pull-down force. Ideal for deck ledger attachment. Cold-rolled carbon steel wire heat treated to grade 5 durability and plated with an HCR® finish to prevent red rust. HCR® is tested and recognized for use in ground contact pressure treated lumber for exterior, fresh water general construction applications (e.g. AWPA UC1-UC4A, UCFA).

• Grade 5 durability
• Patented thread serrations require up to 40% less driving torque to increase installation speed
• Built-on washer head designs eliminate the need and extra cost of a separate washer
• Fastener length stamp on the head provides convenient identification without measuring and aids on-site inspections
