T40, E-Coat\u003c\/strong\u003e by Simpson Strong-Tie is a heavy-duty structural fastener engineered for cross-laminated timber (CLT), mass timber construction, and demanding general interior wood applications. The redesigned SDCF Timber-CF screw combines a fully threaded shank, a self-starting SawTooth point, and a sleek black e-coat finish to deliver reliable, long-term performance in timber framing, glulam assembly, beam reinforcement, and engineered wood fastening. Whether you are connecting support beams, fastening wall-to-wall assemblies, or anchoring stud-to-plate connections, this screw offers the strength and ease of installation that structural work requires.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFlat head with underhead nibs -
