Redesigned for performance and reliability, this large-diameter timber screw features a fully threaded shank, a flat countersinking head, and a SawTooth point that makes it suitable for wood-to-wood, wood-to-steel, glulam, engineered wood, and multi-ply fastening projects where uncompromised holding strength is essential.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFlat head with underhead nibs enables clean countersinking for a flush, professional finish - ideal for exposed mass timber and CLT surfaces where aesthetics matter\u003c\/li\u003e\n\u003cli\u003eHeavy-duty, fully-threaded shank along 13 3\/4 in. of thread length provides maximum withdrawal resistance - delivers superior holding power in structural timber connections\u003c\/li\u003e\n\u003cli\u003eSawTooth point ensures fast starts and low installation torque - eliminates the need for predrilling in most applications, speeding up workflow on the job site\u003c\/li\u003e\n\u003cli\u003eBlack e-coat electrocoating finish provides a construction-durable nonmetallic coating for corrosion resistance in interior dry-service applications - protects the fastener while maintaining a clean black appearance\u003c\/li\u003e\n\u003cli\u003eDeep T50 6-lobe recess engages the driver bit securely - reduces cam-out and provides confident, controlled driving even in dense timber materials\u003c\/li\u003e\n\u003cli\u003eCompliant with CSA O86:24 hydrogen embrittlement requirements - meets recognized structural standards for reliability and long-term performance in mass timber construction\u003c\/li\u003e\n\u003cli\u003eOptimized hardness profile helps mitigate risk of brittle fracture - adds a layer of safety and durability in demanding structural applications\u003c\/li\u003e\n\u003cli\u003e0.390 in. outer diameter with a 0.290 in. shank diameter - sized specifically for heavy timber, glulam, engineered wood, and multi-ply fastening where a robust connection is required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy This Product\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt specifically for cross-laminated timber and mass timber construction - the large flat head with nibs, fully threaded shank, and structural-grade hardness profile make this screw a purpose-built solution for CLT and heavy timber projects rather than a general-purpose substitute\u003c\/li\u003e\n\u003cli\u003eNo predrilling required in most applications - the SawTooth point bites into timber quickly and reduces installation torque, which saves significant time when driving large-diameter screws into dense engineered wood or glulam members\u003c\/li\u003e\n\u003cli\u003eBlack e-coat electrocoating provides a durable nonmetallic finish that resists corrosion in interior dry-service conditions - the coating also enhances the appearance of the fastener in visible timber applications where finish quality is important\u003c\/li\u003e\n\u003cli\u003eCSA O86:24 compliance and optimized hardness profile address hydrogen embrittlement concerns -
