T-STAR PLUS CYLINDRIC HEAD WIROX® TRUSS SCREW
SPAX® T-STARplus® Head truss fasteners with WIROX® coating are designed for interior framing applications, specifically truss/rafter connections.
Available in: #14 diameter
Purchase Options:
Material & Coating
Cold-rolled carbon steel wire, heat treated for strength and durability, and plated with WIROX® finish to prevent red rust. WIROX® is tested for use in untreated and above ground contact pressure treated lumber for interior dry/damp general construction applications (e.g., AWPA UC1-UC2, UCFA).
Features
- T-STARplus® - Provides superior bit engagement to eliminate camming out and to facilitate single hand, overhead driving.
- Cylindric Head - Has a low splitting effect and pulls flush into the wood substrate.
- Serrated threads - Dramatically increase installation speed by cutting through the wood fibers.
- 4CUT™ Point provides for a quick and easy installation with no pre-drilling.
- Ideal replacement for hurricane clips in Top plate / Truss-Rafter connection.

ALLOWABLE WITHDRAWAL (W) AND HEAD PULL-THROUGH (P) DESIGN VALUES
- Shear strength is determined in accordance with AISI S904 using minor thread diameter when fastener is tested in threaded section.
- Tabulated pull-through values shall be adjusted by all applicable adjustment factors per NDS Table 11.3.1.
- For wood species with an assigned specific gravity greater than 0.50, use the tabulated values for specific gravity of 0.50.
- Tabulated withdrawal values shall be adjusted by all applicable adjustment factors per NDS Table 11.3.1.
For wood species with an assigned specific gravity between 0.42 and 0.50, use the tabulated values for specific gravity of 0.42. For wood species with an assigned specific gravity between 0.50 and 0.55, use the tabulated values for specific gravity of 0.50. For wood species,= with an assigned specific gravity greater than or equal to 0.55, use the tabulated values for specific gravity of 0.55.
