With a fully threaded shank measuring 18 3\/4 in. of thread length, a SawTooth point for fast, clean starts, and a black e-coat electrocoating finish, this screw delivers both installation efficiency and long-term corrosion resistance in interior dry-service environments. Whether you are fastening glulam beams, reinforcing structural members, or connecting cross-laminated timber panels, this robust cylinder-head screw provides the holding power and clean aesthetics professionals demand. Each box contains 50 screws plus a T50 6-lobe driver bit.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCompact cylinder head - helps countersink the screw for a clean finish whether left exposed or fully recessed, ideal for visible timber applications\u003c\/li\u003e\n\u003cli\u003eHeavy-duty, fully threaded shank (18 3\/4 in. thread length) - provides exceptional withdrawal resistance across the full length of the fastener for superior structural holding power in large timber members\u003c\/li\u003e\n\u003cli\u003eSawTooth point - enables fast starts and easy driving, reducing installation torque and eliminating the need for predrilling in most applications to save time on the job site\u003c\/li\u003e\n\u003cli\u003eBlack e-coat electrocoating finish - delivers a construction-durable nonmetallic coating for corrosion resistance in interior dry-service applications, while the black color enhances aesthetics on exposed timber\u003c\/li\u003e\n\u003cli\u003eDeep T50 6-lobe recess -

at 19 5\/8 in. in length with an 18 3\/4 in. thread length, this screw is purpose-built for thick structural assemblies including mass timber, cross-laminated timber, and multi-ply engineered wood where shorter fasteners simply cannot provide adequate penetration or withdrawal resistance.\u003c\/li\u003e\n\u003cli\u003eNo predrilling required in most applications - the SawTooth point significantly reduces installation torque and eliminates a time-consuming prep step on most timber framing jobs, improving productivity without sacrificing connection strength.\u003c\/li\u003e\n\u003cli\u003eClean finish on exposed timber work - the compact cylinder head is designed to countersink flush or slightly below the surface, leaving a professional, unobtrusive appearance on visible beam and timber faces where aesthetics matter alongside structural performance.\u003c\/li\u003e\n\u003cli\u003eBlack e-coat finish addresses both durability and aesthetics - the nonmetallic electrocoating provides corrosion resistance for interior dry-service use while the black color complements natural and engineered wood surfaces commonly found in contemporary heavy timber architecture.\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\u003eModel Number:\u003c\/strong\u003e SDCFC10X500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 19 5\/8 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter:\u003c\/strong\u003e 0.290 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter:\u003c\/strong\u003e 0.528 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length:\u003c\/strong\u003e 18 3\/4 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type:\u003c\/strong\u003e T50 6-Lobe\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type:\u003c\/strong\u003e Cylinder Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type:\u003c\/strong\u003e SawTooth 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\u003eApproved Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEngineered Wood\u003c\/li\u003e\n\u003cli\u003eFastening Wood-to-Wood\u003c\/li\u003e\n\u003cli\u003eTimber Framing\u003c\/li\u003e\n\u003cli\u003eBeam Reinforcement\u003c\/li\u003e\n\u003cli\u003eFastening Wall-to-Wall\u003c\/li\u003e\n\u003cli\u003eFastening Support Beams\u003c\/li\u003e\n\u003cli\u003eHeavy Timber\u003c\/li\u003e\n\u003cli\u003eGlulam\u003c\/li\u003e\n\u003cli\u003eFastening Butt Joists\u003c\/li\u003e\n\u003cli\u003eMass Timber \/ Cross-Laminated Timber\u003c\/li\u003e\n\u003cli\u003eEngineered Wood -
