The redesigned SDCFC Timber-CFC screw combines a fully threaded shank for maximum withdrawal resistance with a compact cylinder head that delivers a clean, professional finish whether left exposed or countersunk. The SawTooth point enables fast starts and easy driving, while the black e-coat electrocoating finish enhances aesthetics and provides reliable corrosion resistance in interior dry-service conditions - making this screw a dependable choice for fastening large wood members, glulam beams, engineered wood assemblies, and cross-laminated timber structures.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact cylinder head design\u003c\/strong\u003e -
