Designed for use with large members including mass timber, cross-laminated timber, glulam beams, and engineered wood assemblies, this cylinder-head screw combines a fully threaded shank with a SawTooth point to deliver exceptional withdrawal resistance and fast, clean installation. The black e-coat electrocoating finish provides a construction-durable nonmetallic corrosion barrier suited for interior dry-service environments, while the deep T40 6-lobe drive recess ensures reliable torque transfer with reduced cam-out risk.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCompact cylinder head design - helps countersink the screw flush for a clean exposed finish or a fully concealed appearance when driven below the surface\u003c\/li\u003e\n\u003cli\u003eHeavy-duty, fully threaded shank - maximizes withdrawal resistance along the entire fastener length, providing superior holding power in wood-to-wood connections\u003c\/li\u003e\n\u003cli\u003eSawTooth point - enables fast starts and easy driving while reducing installation torque, eliminating the need for predrilling in most applications and speeding up workflow\u003c\/li\u003e\n\u003cli\u003eBlack e-coat electrocoating finish - delivers a construction-durable nonmetallic coating that resists corrosion in interior dry-service applications while enhancing aesthetics with a consistent black color\u003c\/li\u003e\n\u003cli\u003eDeep T40 6-lobe recess - provides a secure, positive drive engagement that reduces cam-out and driver slippage, improving installation accuracy and efficiency\u003c\/li\u003e\n\u003cli\u003eOptimized hardness profile - works together with the e-coat finish to help mitigate the risk of brittle fracture, supporting reliable long-term structural performance\u003c\/li\u003e\n\u003cli\u003eCompliant with CSA O86:24 hydrogen embrittlement requirements -
