This partially threaded screw pulls structural members together with exceptional holding power, delivering a clean, flush countersink finish thanks to its flat head with underhead nibs. The black e-coat electrocoating finish reduces drive friction, supports use with fire-retardant-treated (FRT) lumber, and meets ICC-ES AC257 Exposure Condition 3 standards - making it a dependable choice for interior and dry-service structural connections including engineered wood, timber framing, and factory-built or modular construction.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBlack e-coat electrocoating finish -

the SDCP screw's partial thread, heavy-duty shank, and CSA O86:24-compliant hardness profile make it a structurally verified choice for engineered wood and cross-laminated timber assemblies where fastener performance is critical.\u003c\/li\u003e\n\u003cli\u003eEliminates predrilling in most applications - the Type-17 point and low-friction e-coat finish significantly reduce installation time and labor on timber framing, general framing, and modular construction jobsites.\u003c\/li\u003e\n\u003cli\u003eApproved for FRT lumber and Exposure Condition 3 - the black e-coat electrocoating meets ICC-ES AC257 requirements, so these screws are compatible with fire-retardant-treated lumber used in many interior commercial and residential structural applications.\u003c\/li\u003e\n\u003cli\u003eReduces brittleness risk in structural fastening - the optimized hardness profile directly addresses hydrogen embrittlement concerns that can compromise structural integrity, providing added confidence in long-term wood-to-wood load capacity.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Simpson Strong-Tie\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Strong-Drive SDCP TIMBER-CP Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 8 mm x 220 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 8 5\/8 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length:\u003c\/strong\u003e 3 1\/8 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter:\u003c\/strong\u003e 0.225 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter:\u003c\/strong\u003e 0.575 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type:\u003c\/strong\u003e Flat Head with Nibs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type:\u003c\/strong\u003e T40 6-Lobe\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type:\u003c\/strong\u003e Type-17 Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating:\u003c\/strong\u003e E-coat Electrocoating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e E-coat Electrocoating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cstrong\u003e\n\u003ch3\u003eAvailable Pack Options\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSDCP8X220-R50:\u003c\/strong\u003e 50 Pk -
