Description

Simpson Strong-Tie SDWS Interior Timber Screws are built for strength, speed, and simplicity, perfect for DIYers tackling framing or heavy wood connections indoors. Whether you're finishing a basement, building sturdy shelving, or constructing a workshop, these structural screws give you the muscle to get it done right.

With their coarse thread design and smooth upper shank, they drive fast and pull materials tight without the need to pre-drill. The large washer-style head delivers serious clamping force for long-lasting joints you can trust.

Optimized for dry environments, these interior-grade screws are a reliable choice for all your indoor structural wood projects, from walls to workbenches and beyond.

Key Features:

  • Interior-Grade Finish – Made for dry, controlled environments like basements, workshops, and living spaces.
  • Drives Fast with No Pre-Drilling – Saves time and effort thanks to the sharp tip and aggressive threading.
  • Oversized Washer Head – Distributes load and clamping pressure for a secure, long-lasting hold.
  • Smooth Upper Shank – Pulls boards together tightly to create flush, gap-free connections.

Fasteners Plus made it happen.

We had a glitch in shipping but when I contacted Heather and explained what happened she dealt with it promptly and expedited the shipping. The product was just what I needed and the service was extraordinary. I will definitely use Fasteners Plus again.
