Technical Features
- Climatek (Climacoat) Coating: Yellow corrosion-resistant finish rated for both interior and exterior exposure, extending service life in outdoor structural applications.
- Specially Hardened Steel Construction: Provides the tensile and shear strength required for load-bearing structural connections such as beam-to-beam and ledger-board installations.
- W-Cut Zip Tip Thread Design: Self-tapping thread geometry reduces installation torque and eliminates the need for pre-drilling, accelerating fastening speed on the job site.
- Washer Head Design: Integrated washer head distributes clamping load over a wider bearing surface, reducing pull-through risk in structural lumber and engineered wood.
- Star Drive Style: High-engagement drive recess reduces cam-out during high-torque installation, improving control and reducing bit wear.
- Self-Drilling Tip: Sharp point penetrates material without a pilot hole, streamlining installation in field conditions.
- 5/16 in. Diameter x 4 in. Length: Screw dimensions suited for deep structural connections requiring substantial holding power through dimensional lumber.
- 400-Count Boxed Packaging: High-volume pack quantity supports large-scale structural framing and decking projects with reduced resupply frequency.
Applications
- Carrying beam and header connections
- Ledger board attachment to house framing
- Deck post and stair rail fastening
- Playground structure assembly
