Redesigned for demanding structural work, this flat-head timber screw delivers uncompromised holding power in heavy timber framing, glulam assemblies, engineered wood multi-ply fastening, and beam reinforcement. The black e-coat electrocoating finish offers a clean, professional appearance alongside reliable corrosion resistance in interior dry-service environments, making it a dependable choice for both large-scale mass timber projects and precision interior structural connections.\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 -
