  • ULTIMATE STRUCTURAL CLAMPING The partial thread design allows the shank to bypass the outer beam, pulling thick timbers together for a gap-free, permanent structural bond.
  • DEEP-CORE ANCHORING The 5.5 reach is optimized for connecting 4x4 posts or multi-layer beams, providing elite withdrawal resistance and structural stability.
  • 304 MARINE-GRADE DEFENSE Forged from premium 304 (18-8) stainless steel to endure high humidity and prevent rust staining in cedar, redwood, or ACQ lumber.
  • STABLE TORQUE DELIVERY Robust hex head fits standard 1/2 socket drives, delivering maximum torque transfer for controlled installation in dense timber.
  • TECHNICAL SPECIFICATION To ensure structural safety and prevent splitting, pre-drilling a pilot hole (3/16 for softwoods, 7/32 for hardwoods) is mandatory.
