T40, E-Coat\u003c\/strong\u003e by Simpson Strong-Tie is a heavy-duty structural wood screw engineered for demanding large-member fastening applications including mass timber, glulam beams, cross-laminated timber, and heavy timber framing. The redesigned SDCFC Timber-CFC screw features a fully threaded shank for superior withdrawal resistance, a compact cylinder head for a clean exposed or countersunk finish, and a SawTooth point that enables fast starts and easy driving without predrilling in most applications. The black e-coat electrocoating finish delivers a construction-durable nonmetallic surface that resists corrosion in interior dry-service conditions, while the optimized hardness profile helps mitigate the risk of brittle fracture for reliable, long-term structural performance.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact cylinder head\u003c\/strong\u003e -
