At nearly 24 inches in length with a fully threaded shank, this timber fastener delivers exceptional withdrawal resistance and holding power in demanding wood-to-wood, wood-to-steel, and engineered lumber connections. The black e-coat electrocoating finish and optimized hardness profile make it a reliable long-term solution for interior dry-service framing, glulam beam reinforcement, timber framing, and multi-ply engineered wood fastening.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlat head with underhead nibs\u003c\/strong\u003e -
