Product Details

Designed to provide an easy-to-install, high-strength alternative to through-bolting and traditional lag screws. The Strong-Drive SDWS Timber Screw (Exterior Grade) is ideal for the contractor and do-it-yourselfer alike. It is code Listed under IAPMO UES ER-192 and meets 2015 and 2018 IRC and IBC code requirements for several common wood framing applications.
  • SawTooth point ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications
  • Bold thread design provides superior holding power
  • Underhead nibs offer greater control when seating the head
  • Large low-profile washer head provides maximum bearing area (0.75 in. head Dia)
  • Size identification on all SDWS screw heads
  • 6-lobe T40 drive provides positive engagement that makes the screw easy to drive and improves bit life (replacement driver bit BIT40T-134-RC)
  • Length: 8 in.
  • Double-barrier coating provides corrosion resistance equivalent to hot-dip galvanization, making it suitable for certain exterior and preservative-treated wood applications, as described in the evaluation report
  • Quantity: 50
  • Return Policy
  • California residents

        Q:What's the recommended predrill bit size?
        by|Jan 18, 2023
        1 Answer
        Answer This Question

        A:  Hi Paul, this screw can often be installed without the need for predrilling, but when installing into denser materials, dry lumber or lumber more likely to split, or knots that make predrilling necessary, a 5/32" drill bit is recommended. Hope that helps.

          The threads are to small, to easy to strip out the wood.

          These are the best bolts on the market hands down! They go in easy, lock down tight and are incredibly strong.

          As a professional deck builder I keep every size of these bolts on site. Strong shafts with huge flat heads grippy threads and star bits that don’t slip! I’ve tried the competition and these are the best. Stock up while there’re on sale!
