T20, Quik Guard, Tan 01, 70-Pack (DCU234TN01R70) is a hand-drive composite decking screw made for fastening composite deck boards with a cleaner finished look. This is a composite decking screw designed for deck board fastening. Model Number: DCU234TN01R70. For deck builders, remodelers, and serious DIY users working with composite or PVC decking, the point of this screw is simple: drive easier, leave less mess at the surface, and end up with a more professional-looking deck.\u003c\/p\u003e\n      \u003cp\u003eWhat sets the DCU screw apart is how the thread and head work together in composite material. The tri-lobe thread design helps reduce damage to the board while driving, and the inverted upper threads clear excess material on the way in. In real use, that means less tearing and less buildup around the top of the hole. The cap head is there for the same reason. It helps prevent mushrooming and keeps material from pushing up above the deck surface, which is a common headache when fastening composite boards.\u003c\/p\u003e\n      \u003cp\u003eThe Type-17 point is built for fast starts in decking material, so the screw gets moving without a lot of skating or wandering. Pair that with the T20 6-lobe drive and you get solid bit engagement, which matters when you are driving repeated fasteners across a full deck. Better drive engagement means less cam-out, less stripped recesses, and less time fighting the screw instead of finishing the job.\u003c\/p\u003e\n      \u003cp\u003eThis version uses Quik Guard coating over carbon steel for corrosion resistance suited to medium-corrosion environments. That makes it a practical fit for many exterior deck builds where you need protection beyond plain steel. The painted Tan 01 head is also part of the value here. On composite decking, color matters. A closer head match makes the finished surface look cleaner and less distracting than a bright exposed fastener.\u003c\/p\u003e\n      \u003cp\u003eOn the sizing side, this screw is a #10 x 2-3\/4 in. fastener with a 0.230 in. head diameter and a 70-piece package count. The 2-3\/4 in. length is specifically called out as an approved fastener by Trex for Trex composite decking, which gives buyers a clear compatibility reference when they are trying to stay inside manufacturer guidance. Simpson Strong-Tie also notes that the DCU line is available for hand-drive applications and in collated versions for the Quik Drive system, so the platform makes sense whether you are handling a small repair or standardizing across larger deck installs.\u003c\/p\u003e\n      \u003cp\u003eWho should buy this one? Anyone building or repairing composite decking who wants a screw made for the material instead of forcing a generic exterior screw to do the job. It is a good fit for deck crews, carpenters, remodeling contractors, and homeowners replacing boards or building smaller sections. If appearance matters, if you want less mushrooming, and if you want a screw approved for Trex at this length, this is the right type of fastener to be looking at.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eCleaner Results on Composite Boards\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"row\"\u003e\n        \u003cdiv class=\"img\"\u003e\n          \u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/10501349802278_94369f0806cd.jpg\" alt=\"Simpson Strong-Tie Deck-Drive DCU COMPOSITE Screw, #10 x 2-3\/4-in.
