The combination hex and 6-lobe head design gives installers the flexibility to drive with either a 15 mm hex-head bit or a T40 6-lobe bit, reducing tool dependency on the job site. Built with a robust knurled shank, a Type-17 self-drilling point, and a black e-coat electrocoating finish, this screw delivers reliable connection strength in dry-service structural conditions - including steel-to-wood and engineered wood assemblies.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBlack e-coat electrocoating finish - provides a construction-durable, nonmetallic, and friction-reducing surface for corrosion resistance in interior dry-service conditions, keeping connections protected without metallic coatings\u003c\/li\u003e\n\u003cli\u003eOptimized hardness profile - helps mitigate field embrittlement issues and is compliant with CSA O86:24 hydrogen embrittlement requirements, giving builders confidence in structural integrity\u003c\/li\u003e\n\u003cli\u003eCombination (combo) head with T40 6-lobe recess and 15 mm hex compatibility - allows use of either driver type for a secure, slip-resistant drive in demanding applications\u003c\/li\u003e\n\u003cli\u003eHeavy-duty shank with robust knurl - reduces installation torque during driving, helping installers work faster with less effort\u003c\/li\u003e\n\u003cli\u003eType-17 point - ensures fast starts, reduces torque during driving, and eliminates the need for predrilling in most wood applications, saving significant time on large timber projects\u003c\/li\u003e\n\u003cli\u003eDesigned for use with steel side plates - makes this screw a dependable choice for steel-to-wood structural connections including angle connectors and plate hardware\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank - thread length of 4 3\/8 in. draws connected members tightly together for strong, gap-free structural joints\u003c\/li\u003e\n\u003cli\u003e6 1\/4 in.
