Description

SPAX® T-STAR plus Wafer Head fasteners with HCR-X™ coating are designed for use in multiple material connections often found outside residential dwellings. These fasteners are designed with a low profile large diameter wafer head for applications requiring additional surface area under the head for superior pull-down force. Ideal for attaching rail, fencing and out building hardware where a flush or countersunk installation is not possible or desired. 

Materials & Coatings

Cold-rolled “carbon steel” wire, heat treated to grade 5 durability and plated with a HCR-X™ finish to prevent red rust. “HCR-X™” is tested and recognized for use in ground contact pressure treated lumber for exterior, freshwater general construction applications (e.g. AWPA UC1- UC4A, UCFA). SPAX® recommends stainless steel fasteners for applications with cedar and redwoods. 

Base Part No.: 328167() and 428167()
