QTY:

Designed to provide an easy-to-install, high-strength alternative to through-bolting and traditional lag screws. The Strong-Drive SDWS Timber screw is ideal for the contractor and do-it-yourselfer alike. It is code listed under IAPMO UES ER-192 and meets 2012 and 2015 IRC® and IBC® code requirements for several common wood framing applications.

Key Features

  • Bold thread design provides superior holding power
  • Patented 4CUT™ tip ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications
  • Under-head nibs offer greater control when seating the head
  • Large washer head provides maximum bearing area (0.75" head dia.)
  • Size identification on all SDWS screw heads
  • 6-lobe T-40 drive reduces driver-bit cam-outs, resulting in easier installations and longer bit life

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.

Applications

  • Structural wood-to-wood connections including ledgers

Product Includes

  • Retail and mini-bulk packs include one 6-lobe, T-40 driver bit; bulk packs include two driver bits
