- ENGINEERED CLAMPING POWER Features a partial thread that allows the smooth shank to bypass the outer member, pulling thick timber together for a gap-free, rock-solid joint.
- DEEP-ANCHOR STABILITY The 3.5-inch length is optimized for securing 2x lumber (1.5 thick) to structural posts, providing elite withdrawal resistance with 2 of deep-core thread engagement.
- 304 EXTERIOR DEFENSE Forged from premium 304 (18-8) stainless steel to prevent rust and staining in cedar, redwood, or ACQ pressure-treated lumber.
- HIGH-TORQUE DRIVE Precision hex head ensuring a secure 1/2 socket fit, providing stable torque transfer for controlled seating in dense structural timber.
- TECHNICAL SPECIFICATION To prevent splitting and protect the 5/16 shaft, pre-drilling a pilot hole (7/32 for softwoods, 1/4 for hardwoods) is mandatory for structural safety.
