The redesigned TIMBER-CFC screw combines a fully threaded shank for superior withdrawal resistance with a compact cylinder head that delivers a clean exposed finish or a concealed look when countersunk - making it a versatile choice for timber framing, beam reinforcement, engineered wood fastening, and cross-laminated timber construction. The black e-coat electrocoating provides corrosion resistance in interior dry-service applications while giving the fastener a refined, professional appearance.\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 -
